07-博客系统之创建系统与迁移表
1、注释默认的sqllite数据库，修改为MySQL数据库；
2、编写models.py;
from django.db import models # Create your models here. from django.contrib.auth.models import AbstractUser class UserInfo(AbstractUser): """ 用户信息 """ nid = models.AutoField(primary_key=True) telephone = models.CharField(max_length=11, null=True, unique=True) avatar = models.FileField(upload_to='avatars/', default="/avatars/default.png") create_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True) blog = models.OneToOneField(to='Blog', to_field='nid', null=True, on_delete=models.CASCADE) def __str__(self): return self.username class Blog(models.Model): """ 博客信息 """ nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='个人博客标题', max_length=64) site_name = models.CharField(verbose_name='站点名称', max_length=64) theme = models.CharField(verbose_name='博客主题', max_length=32) def __str__(self): return self.title class Category(models.Model): """ 博主个人文章分类表 """ nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='分类标题', max_length=32) blog = models.ForeignKey(verbose_name='所属博客', to='Blog', to_field='nid', on_delete=models.CASCADE) def __str__(self): return self.title class Tag(models.Model): nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='标签名称', max_length=32) blog = models.ForeignKey(verbose_name='所属博客', to='Blog', to_field='nid', on_delete=models.CASCADE) def __str__(self): return self.title class Article(models.Model): nid = models.AutoField(primary_key=True) title = models.CharField(max_length=50, verbose_name='文章标题') desc = models.CharField(max_length=255, verbose_name='文章描述') create_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True) content = models.TextField() comment_count = models.IntegerField(default=0) up_count = models.IntegerField(default=0) down_count = models.IntegerField(default=0) user = models.ForeignKey(verbose_name='作者', to='UserInfo', to_field='nid', on_delete=models.CASCADE) category = models.ForeignKey(to='Category', to_field='nid', null=True, on_delete=models.CASCADE) tags = models.ManyToManyField( to="Tag", through='Article2Tag', through_fields=('article', 'tag'), ) def __str__(self): return self.title class Article2Tag(models.Model): nid = models.AutoField(primary_key=True) article = models.ForeignKey(verbose_name='文章', to="Article", to_field='nid', on_delete=models.CASCADE) tag = models.ForeignKey(verbose_name='标签', to="Tag", to_field='nid', on_delete=models.CASCADE) class Meta: unique_together = [ ('article', 'tag'), ] def __str__(self): v = self.article.title + "---" + self.tag.title return v class ArticleUpDown(models.Model): """ 点赞表 """ nid = models.AutoField(primary_key=True) user = models.ForeignKey('UserInfo', null=True, on_delete=models.CASCADE) article = models.ForeignKey("Article", null=True, on_delete=models.CASCADE) is_up = models.BooleanField(default=True) class Meta: unique_together = [ ('article', 'user'), ] class Comment(models.Model): """ 评论表 """ nid = models.AutoField(primary_key=True) article = models.ForeignKey(verbose_name='评论文章', to='Article', to_field='nid', on_delete=models.CASCADE) user = models.ForeignKey(verbose_name='评论者', to='UserInfo', to_field='nid', on_delete=models.CASCADE) content = models.CharField(verbose_name='评论内容', max_length=255) create_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True) parent_comment = models.ForeignKey('self', null=True, on_delete=models.CASCADE) def __str__(self): return self.content
3、settingsp.py添加AUTH_USER_MODEL=“blog.UserInfo”;
""" Django settings for cnblogs project. Generated by 'django-admin startproject' using Django 2.1.

4、进行数据库迁移操作；
python manage.py makemigrations
python manage.py migrate
08-博客系统之登录页面设计
1、登录页面设计；
2、login.html设计之引入本地Bootstrap静态文件;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> </head> <body> <h3>登录页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form action=""> <div class="form-group"> <label for="user">用户名</label> <input type="text" id="user" class="form-control"> </div> <div class="form-group"> <label for="pwd">密码</label> <input type="password" id="pwd" class="form-control"> </div > <input type="button" class="btn btn-default pull-right login_btn" value="submit"> </form> </div> </div> </div> </body> </html>
3、views.py;
from django.shortcuts import render # Create your views here. def login(request): return render(request,"login.html")
4、settings.py之配置STATICFILE_DIRS目录;
STATICFILES_DIRS = [ os.path.join(BASE_DIR,"static") ]
09-博客系统之验证码图片的生成1
1、PIL图像处理模块初识；
PIL：Python Imaging Library，已经是Python平台事实上的图像处理标准库了，PIL功能非常强大，且API非常简单易用。
由于PIL仅支持到Python 2.7，加上年久失修，于是一群志愿者在PIL的基础上创建了兼容的版本，名字叫Pillow，支持最新Python 3.x，又加入了许多新特性，因此，我们可以直接安装使用Pillow。
pip install pillow
2、打开图片的两种方式；
from django.shortcuts import render,HttpResponse,redirect # Create your views here. def login(request): return render(request,"login.html") import random def get_validCode_img(request): def get_random_color(): return (random.randint(0,255),random.randint(0,255),random.randint(0,255)) #方式1-with open方法； # with open("lufei.jpg","rb") as f: # data = f.read() #方式2；pip install pillow; from PIL import Image img = Image.new("RGB",(270,40),color=get_random_color()) with open("validCode.png","wb") as f: img.save(f,"png") with open("validCode.png","rb") as f: data = f.read() return HttpResponse(data)
3、login.html;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> </head> <body> <h3>登录页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form action=""> {% csrf_token %} <div class="form-group"> <label for="user">用户名</label> <input type="text" id="user" class="form-control"> </div> <div class="form-group"> <label for="pwd">密码</label> <input type="password" id="pwd" class="form-control"> </div > <div class="form-group"> <label for="pwd">验证码</label> <div class="row"> <div class="col-md-6"> <input type="text" class="valid_code form-control"> </div> <div class="col-md-6"></div> <img width="260" height="45" src="/get_validCode_img/" alt=""> </div> </div> <input type="button" class="btn btn-default pull-right login_btn" value="submit"> </form> </div> </div> </div> </body> </html>
10-博客系统之验证码图片的生成2
1、生成随机字符串的两种方法；
2、引入string、ImageDraw、ImageFont模块；
from django.shortcuts import render,HttpResponse,redirect # Create your views here. def login(request): return render(request,"login.html") import random def get_validCode_img(request): def get_random_color(): return (random.randint(0,255),random.randint(0,255),random.randint(0,255)) #方式1-with open方法； # with open("lufei.jpg","rb") as f: # data = f.read() #方式2；pip install pillow; # from PIL import Image # img = Image.new("RGB",(270,40),color=get_random_color()) # with open("validCode.png","wb") as f: # img.save(f,"png") # with open("validCode.png","rb") as f: # data = f.read() #方式3：将数据放置于内存中，加快处理速度； # from PIL import Image # from io import BytesIO # # img = Image.new("RGB",(270,40),color=get_random_color()) # f = BytesIO() # img.save(f,"png") # data = f.getvalue() #方式4:向图像区域他添加噪点，和字符串； from PIL import Image,ImageDraw,ImageFont from io import BytesIO import random char = str(random.randint(0,9)) img = Image.new("RGB",(270,40),color=get_random_color()) draw = ImageDraw.Draw(img) kumo_font = ImageFont.truetype("static/font/kumo.ttf",size=28) #生成随机字符串； #方法1： # for i in range(0,5): # import string # random_char = ' '.join(random.sample(string.ascii_lowercase + string.ascii_uppercase,1)) # d4}5c+/m|97e@"16]s # draw.text((i*50+20,5),random_char,get_random_color(),font=kumo_font) #方法2： for i in range(5): random_num = str(random.randint(0,9)) random_lowercase = chr(random.randint(95,122)) random_uppercase = chr(random.randint(65,90)) random_char = random.choice([random_num,random_lowercase,random_uppercase]) draw.text((i*50+20,5),random_char,get_random_color(),font=kumo_font) #进行画图 #draw.line() #draw.point() f = BytesIO() img.save(f,"png") data = f.getvalue() return HttpResponse(data)
11-博客系统之验证码图片的噪点燥线
1、添加噪点、燥线；
#给图片添加上噪点； width = 270 height = 40 for i in range(5): x1 = random.randint(0,width) x2 = random.randint(0,width) y1 = random.randint(0,height) y2 = random.randint(0,height) draw.line((x1,y1,x2,y2),fill=get_random_color()) for i in range(10): draw.point([random.randint(0,width),random.randint(0,height)],fill=get_random_color()) x = random.randint(0,width) y = random.randint(0,height) draw.arc((x,y,x+4,y+4),0,90,fill=get_random_color())
2、展示效果；
12-博客系统之验证码刷新
1、先引入jQuery文件；
2、添加鼠标点击事件click();
3、给图片添加一个id属性，然后通过js代码添加事件；
<script src="/static/blog/js/jquery-3.3.1.min.js"></script> <script> //刷新图片验证码； $("#valid_code_img").click(function () { $(this)[0].src+="?" }) </script>
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> </head> <body> <h3>登录页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form action=""> {% csrf_token %} <div class="form-group"> <label for="user">用户名</label> <input type="text" id="user" class="form-control"> </div> <div class="form-group"> <label for="pwd">密码</label> <input type="password" id="pwd" class="form-control"> </div > <div class="form-group"> <label for="pwd">验证码</label> <div class="row"> <div class="col-md-6"> <input type="text" class="valid_code form-control"> </div> <div class="col-md-6"> <img width="260" height="45" id="valid_code_img" src="/get_validCode_img/" alt="">
</div> </div> </div> <input type="button" class="btn btn-default pull-right login_btn" value="submit"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <script> //刷新图片验证码； $("#valid_code_img").click(function () { $(this)[0].src+="?" }) </script> </body> </html>
13-博客系统之保存验证码字符串
1、保存验证字符串之Ajax引入；
2、views.py;
from django.shortcuts import render,HttpResponse,redirect # Create your views here. from django.http import JsonResponse def login(request): if request.method == "POST": response = {"user":None,"msg":None} user = request.POST.get("user") pwd = request.POST.get("pwd") valid_code = request.POST.get("valid_code") valid_code_str = request.session.get("valid_code_str") #print("valid_code_str",valid_code_str,type(valid_code_str)) #print("valid_code",valid_code,type(valid_code)) if valid_code.upper() == valid_code_str.upper(): pass else: response["msg"] = "valid code error!" return JsonResponse(response) return render(request,"login.html") import random def get_validCode_img(request): def get_random_color(): return (random.randint(0,255),random.randint(0,255),random.randint(0,255)) #方式1-with open方法； # with open("lufei.jpg","rb") as f: # data = f.read() #方式2；pip install pillow; # from PIL import Image # img = Image.new("RGB",(270,40),color=get_random_color()) # with open("validCode.png","wb") as f: # img.save(f,"png") # with open("validCode.png","rb") as f: # data = f.read() #方式3：将数据放置于内存中，加快处理速度； # from PIL import Image # from io import BytesIO # # img = Image.new("RGB",(270,40),color=get_random_color()) # f = BytesIO() # img.save(f,"png") # data = f.getvalue() #方式4-向图像区域他添加噪点，和字符串； from PIL import Image,ImageDraw,ImageFont from io import BytesIO import random char = str(random.randint(0,9)) img = Image.new("RGB",(270,40),color=get_random_color()) draw = ImageDraw.Draw(img) kumo_font = ImageFont.truetype("static/font/BASKVILL.TTF",size=28) #保存随机字符串； valid_code_str = "" #生成随机字符串； #方法1： for i in range(0,5): import string random_char = ' '.join(random.sample(string.ascii_lowercase + string.ascii_uppercase,1)) # d4}5c+/m|97e@"16]s draw.text((i*50+20,5),random_char,get_random_color(),font=kumo_font) #保存验证码字符串； valid_code_str+= random_char #方法2： # for i in range(500): # random_num = str(random.randint(0,9)) # random_lowercase = chr(random.randint(95,122)) # random_uppercase = chr(random.randint(65,90)) # random_char = random.choice([random_num,random_lowercase,random_uppercase]) # draw.text((i*50+20,5),random_char,get_random_color(),font=kumo_font) #进行画图； #draw.line() #draw.point() #给图片添加上噪点； width = 270 height = 40 for i in range(5): x1 = random.randint(0,width) x2 = random.randint(0,width) y1 = random.randint(0,height) y2 = random.randint(0,height) draw.line((x1,y1,x2,y2),fill=get_random_color()) for i in range(10): draw.point([random.randint(0,width),random.randint(0,height)],fill=get_random_color()) x = random.randint(0,width) y = random.randint(0,height) draw.arc((x,y,x+4,y+4),0,90,fill=get_random_color()) print("valid_code_str",valid_code_str) request.session["valid_code_str"] = valid_code_str ''' 1、生成随机字符串； 2、COOKIE{"sessionid":fdsfdsfds} 3、django-session表生成记录； ''' f = BytesIO() img.save(f, "png") data = f.getvalue() return HttpResponse(data)

16-博客系统之滑动验证码作业
17-博客系统之基于form组件的注册页面设计1
1、注册页面的路由配置urls.py;
"""cnblogs URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/2.1/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.contrib import admin from django.urls import path from blog import views urlpatterns = { path('admin/', admin.site.urls), path('login/', views.login), path('index/', views.index), path('get_validCode_img/', views.get_valid_code_img), path('register/', views.register), }
2、注册页面的views.py视图函数编写；
from django.shortcuts import render,HttpResponse,redirect # Create your views here. from django.http import JsonResponse from django.contrib import auth def login(request): """ 登录； :param request: :return: """ if request.method == "POST": response = {"user":None,"msg":None} user = request.POST.get("user") pwd = request.POST.get("pwd") valid_code = request.POST.get("valid_code") valid_code_str = request.session.get("valid_code_str") if valid_code.upper() == valid_code_str.upper(): user = auth.authenticate(username = user,password = pwd) if user: response["user"] = user.username else: response["msg"] = "用户名或者密码错误！" else: response["msg"] = "验证码错误!" return JsonResponse(response) return render(request,"login.html") def get_valid_code_img(request): """ 基于PIL模块动态生成响应状态码图片； :param request: :return: """ from blog.utils.validCode import get_valid_code_img data = get_valid_code_img(request) return HttpResponse(data) def index(request): """ 首页； :param request: :return: """ return render(request,"index.html") from django import forms from django.forms import widgets class UserForm(forms.Form): user = forms.CharField(max_length=32,label="用户名",widget=widgets.TextInput(attrs={"class":"form-control"})) pwd = forms.CharField(max_length=32,label="密码",widget=widgets.PasswordInput(attrs={"class":"form-control"})) r_pwd = forms.CharField(max_length=32,label="确认密码",widget=widgets.PasswordInput(attrs={"class":"form-control"})) email = forms.EmailField(max_length=32,label="注册邮箱",widget=widgets.EmailInput(attrs={"class":"form-control"})) def register(request): """ 注册； :param request: :return: """ form = UserForm() return render(request,"register.html",{"form":form})
3、注册页面的模板templates下的register.html编写（基于forms组件循环生成并添加约束信息）；
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> </head> <body> <h3>注册页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form > {% csrf_token %} <!--进行渲染form对象--> {% for field in form %} <div class="form-group"> <label for="user">{{ field.label }}</label> {{ field }} </div> {% endfor %} <div class="form-group"> <label for="avatar">头像</label> <input type="file"> </div> <input type="button" class="btn btn-default login_btn" value="提交"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> </body> </html>
18-博客系统之注册页面的默认头像
1、点击头像相当于点击input标签的功能实现；
- 1）将label标签包含img标签；
- 2）将label标签的for值等同于input标签的id值；
- 3）为input标签设置display：none的隐藏属性；
2、register.html;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <style> #avatar{ display: none; } #avatar_img{ margin-left: 20px; } </style> </head> <body> <h3>注册页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form > {% csrf_token %} <!--进行渲染form对象--> {% for field in form %} <div class="form-group"> <label for="{{ field.auto_id }}">{{ field.label }}</label> {{ field }} </div> {% endfor %} <div class="form-group"> <label for="avatar"> 头像 <img id="avatar_img" width="60px" height="60px" src="/static/blog/img/default.png" alt=""> </label> <input type="file" id="avatar" > </div> <input type="button" class="btn btn-default login_btn" value="提交"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> </body> </html>
19-博客系统之注册页面的头像预览功能
1、头像预览功能实现的js代码；
2、获取上传后文件的方法；
- $("#avatar")[0].files[0]，得到如下内容：File(11414) {name: "keep.jpg", lastModified: 1531732278496, lastModifiedDate: Mon Jul 16 2018 17:11:18 GMT+0800 (中国标准时间), webkitRelativePath: "", size: 11414, …}
<script> $("#avatar").change(function () { //1、获取用户选中的文件对象； var file_obj = $(this)[0].files[0]; //2、获取文件对象的路径； var reader = new FileReader(); reader.readAsDataURL(file_obj); //3、修改img的src属性值，src= 文件对象的路径； reader.onload = function(){ $("#avatar_img").attr("src",reader.result) }; }) </script>
20-博客系统之基于Ajax的form data数据
1、通过Ajax方法实现向后端传送数据；
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <style> #avatar{ display: none; } #avatar_img{ margin-left: 20px; } </style> </head> <body> <h3>注册页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form > {% csrf_token %} <!--进行渲染form对象--> {% for field in form %} <div class="form-group"> <label for="{{ field.auto_id }}">{{ field.label }}</label> {{ field }} </div> {% endfor %} <div class="form-group"> <label for="avatar"> 头像 <img id="avatar_img" width="60px" height="60px" src="/static/blog/img/default.png" alt=""> </label> <input type="file" id="avatar" > </div> <input type="button" class="btn btn-default reg_btn" value="提交"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <!--编写js代码--> <script> $("#avatar").change(function () { //1、获取用户选中的文件对象； var file_obj = $(this)[0].files[0]; //2、获取文件对象的路径； var reader = new FileReader(); reader.readAsDataURL(file_obj); //3、修改img的src属性值，src= 文件对象的路径； reader.onload = function(){ $("#avatar_img").attr("src",reader.result) }; }); //基于Ajax提交事件； $(".reg_btn").click(function () { var formdata = new FormData(); formdata.append("user",$("#id_user").val()); formdata.append("pwd",$("#id_pwd").val()); formdata.append("r_pwd",$("#id_r_pwd").val()); formdata.append("email",$("#id_email").val()); formdata.append("avatar",$("#avatar")[0].files[0]); formdata.append("csrfmiddlewaretoken",$("[name = 'csrfmiddlewaretoken']").val()); $.ajax({ url:"", type:"post", contentType:false, processData:false, data:formdata, success:function (data) { console.log(data) } }) }) </script> </body> </html>
2、views.py进行逻辑判断；
from django.shortcuts import render,HttpResponse,redirect # Create your views here. from django.http import JsonResponse from django.contrib import auth def login(request): """ 登录； :param request: :return: """ if request.method == "POST": response = {"user":None,"msg":None} user = request.POST.get("user") pwd = request.POST.get("pwd") valid_code = request.POST.get("valid_code") valid_code_str = request.session.get("valid_code_str") if valid_code.upper() == valid_code_str.upper(): user = auth.authenticate(username = user,password = pwd) if user: response["user"] = user.username else: response["msg"] = "用户名或者密码错误！" else: response["msg"] = "验证码错误!" return JsonResponse(response) return render(request,"login.html") def get_valid_code_img(request): """ 基于PIL模块动态生成响应状态码图片； :param request: :return: """ from blog.utils.validCode import get_valid_code_img data = get_valid_code_img(request) return HttpResponse(data) def index(request): """ 首页； :param request: :return: """ return render(request,"index.html") from django import forms from django.forms import widgets from django.http import JsonResponse class UserForm(forms.Form): user = forms.CharField(max_length=32,label="用户名",widget=widgets.TextInput(attrs={"class":"form-control"})) pwd = forms.CharField(max_length=32,label="密码",widget=widgets.PasswordInput(attrs={"class":"form-control"})) r_pwd = forms.CharField(max_length=32,label="确认密码",widget=widgets.PasswordInput(attrs={"class":"form-control"})) email = forms.EmailField(max_length=32,label="注册邮箱",widget=widgets.EmailInput(attrs={"class":"form-control"})) def register(request): """ 注册； :param request: :return: """ #if request.method == "POST": if request.is_ajax(): print(request.POST) form = UserForm(request.POST) response = {"user":None,"msg":None} if form.is_valid(): response["user"] = form.cleaned_data.get("user") else: print(form.cleaned_data) print(form.errors) response["msg"] = form.errors return JsonResponse(response) form = UserForm() return render(request,"register.html",{"form":form})
21-博客系统之基于Ajax提交from data的数据的优化
1、使用serializeArray()方法进行优化；
注意犯的错误，Js中的代码多行注释的方法为:/*被注释的内容，而不是<!--被注释的内容-->*/
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <style> #avatar{ display: none; } #avatar_img{ margin-left: 20px; } </style> </head> <body> <h3>注册页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form id="form"> {% csrf_token %} <!--进行渲染form对象--> {% for field in form %} <div class="form-group"> <label for="{{ field.auto_id }}">{{ field.label }}</label> {{ field }} </div> {% endfor %} <div class="form-group"> <label for="avatar"> 头像 <img id="avatar_img" width="60px" height="60px" src="/static/blog/img/default.png" alt=""> </label> <input type="file" id="avatar" > </div> <input type="button" class="btn btn-default reg_btn" value="提交"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <!--编写js代码--> <script> $("#avatar").change(function () { //1、获取用户选中的文件对象； var file_obj = $(this)[0].files[0]; //2、获取文件对象的路径； var reader = new FileReader(); reader.readAsDataURL(file_obj); //3、修改img的src属性值，src= 文件对象的路径； reader.onload = function(){ $("#avatar_img").attr("src",reader.result) }; }); //基于Ajax提交事件； $(".reg_btn").click(function () { var formdata = new FormData(); console.log($("#form").serializeArray()); var request_data = $("#form").serializeArray(); $.each(request_data,function (index,data) { formdata.append(data.name,data.value) }); formdata.append("avatar",$("#avatar")[0].files[0]); /* var formdata = new FormData(); formdata.append("user",$("#id_user").val()); formdata.append("pwd",$("#id_pwd").val()); formdata.append("r_pwd",$("#id_r_pwd").val()); formdata.append("email",$("#id_email").val()); formdata.append("avatar",$("#avatar")[0].files[0]); formdata.append("csrfmiddlewaretoken",$("[name = 'csrfmiddlewaretoken']").val());*/ $.ajax({ url:"", type:"post", contentType:false, processData:false, data:formdata, success:function (data) { console.log(data) } }) }) </script> </body> </html>
22-博客系统之基于Ajax在注册页面显示错误消息1
1、基于Ajax实现页面错误消息；
register.html;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <style> #avatar{ display: none; } #avatar_img{ margin-left: 20px; } .error{ color: red; } </style> </head> <body> <h3>注册页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form id="form"> {% csrf_token %} <!--进行渲染form对象--> {% for field in form %} <div class="form-group"> <label for="{{ field.auto_id }}">{{ field.label }}</label> {{ field }}<span class="error pull-right"></span> </div> {% endfor %} <div class="form-group"> <label for="avatar"> 头像 <img id="avatar_img" width="60px" height="60px" src="/static/blog/img/default.png" alt=""> </label> <input type="file" id="avatar" name="avatar"> </div> <input type="button" class="btn btn-default reg_btn" value="提交"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <!--编写js代码--> <script> $("#avatar").change(function () { //1、获取用户选中的文件对象； var file_obj = $(this)[0].files[0]; //2、获取文件对象的路径； var reader = new FileReader(); reader.readAsDataURL(file_obj); //3、修改img的src属性值，src= 文件对象的路径； reader.onload = function(){ $("#avatar_img").attr("src",reader.result) }; }); //基于Ajax提交事件； $(".reg_btn").click(function () { var formdata = new FormData(); console.log($("#form").serializeArray()); var request_data = $("#form").serializeArray(); $.each(request_data,function (index,data) { formdata.append(data.name,data.value) }); formdata.append("avatar",$("#avatar")[0].files[0]); /* var formdata = new FormData(); formdata.append("user",$("#id_user").val()); formdata.append("pwd",$("#id_pwd").val()); formdata.append("r_pwd",$("#id_r_pwd").val()); formdata.append("email",$("#id_email").val()); formdata.append("avatar",$("#avatar")[0].files[0]); formdata.append("csrfmiddlewaretoken",$("[name = 'csrfmiddlewaretoken']").val());*/ $.ajax({ url:"", type:"post", contentType:false, processData:false, data:formdata, success:function (data) { console.log(data); if(data.user){ //注册成功； }else { //console.log(data.msg) $.each(data.msg,function (field,error_list) { console.log(field,error_list); $("#id_"+field).next().html(error_list[0]) }) } } }); }); </script> </body> </html>
23-博客系统之基于Ajax在注册页面显示错误消息2
1、addClass以及removeClass以及Bootstrap中has-error的使用；
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <style> #avatar{ display: none; } #avatar_img{ margin-left: 20px; } .error{ color: red; } </style> </head> <body> <h3>注册页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form id="form"> {% csrf_token %} <!--进行渲染form对象--> {% for field in form %} <div class="form-group"> <label for="{{ field.auto_id }}">{{ field.label }}</label> {{ field }}<span class="error pull-right"></span> </div> {% endfor %} <div class="form-group"> <label for="avatar"> 头像 <img id="avatar_img" width="60px" height="60px" src="/static/blog/img/default.png" alt=""> </label> <input type="file" id="avatar" name="avatar"> </div> <input type="button" class="btn btn-default reg_btn" value="提交"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <!--编写js代码--> <script> $("#avatar").change(function () { //1、获取用户选中的文件对象； var file_obj = $(this)[0].files[0]; //2、获取文件对象的路径； var reader = new FileReader(); reader.readAsDataURL(file_obj); //3、修改img的src属性值，src= 文件对象的路径； reader.onload = function(){ $("#avatar_img").attr("src",reader.result) }; }); //基于Ajax提交事件； $(".reg_btn").click(function () { var formdata = new FormData(); console.log($("#form").serializeArray()); var request_data = $("#form").serializeArray(); $.each(request_data,function (index,data) { formdata.append(data.name,data.value) }); formdata.append("avatar",$("#avatar")[0].files[0]); /* var formdata = new FormData(); formdata.append("user",$("#id_user").val()); formdata.append("pwd",$("#id_pwd").val()); formdata.append("r_pwd",$("#id_r_pwd").val()); formdata.append("email",$("#id_email").val()); formdata.append("avatar",$("#avatar")[0].files[0]); formdata.append("csrfmiddlewaretoken",$("[name = 'csrfmiddlewaretoken']").val());*/ $.ajax({ url:"", type:"post", contentType:false, processData:false, data:formdata, success:function (data) { console.log(data); if(data.user){ //注册成功； }else {//注册失败 //console.log(data.msg) //清空错误提示消息； $("span.error").html(); $(".form-group").removeClass("has-error"); //展示此次提提交的信息； $.each(data.msg,function (field,error_list) { console.log(field,error_list); $("#id_"+field).next().html(error_list[0]); $("#id_"+field).parent().addClass("has-error"); }) } } }); }); </script> </body> </html>
24-博客系统之form组件的局部钩子与全局钩子的应用
1、form组件中的钩子和全局钩子应用；
#!/usr/bin/env python3

2、from django.core.exceptions import NON_FIELD_ERRORS, ValidationError的引入；
3、抛出中文异常的方法；
4、cleaned_data的用法；
register.html;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <style> #avatar{ display: none; } #avatar_img{ margin-left: 20px; } .error{ color: red; } </style> </head> <body> <h3>注册页面</h3> <div class="container"> <div class="row"> <div class="col-md-6 col-lg-offset-3"> <form id="form"> {% csrf_token %} <!--进行渲染form对象--> {% for field in form %} <div class="form-group"> <label for="{{ field.auto_id }}">{{ field.label }}</label> {{ field }}<span class="error pull-right"></span> </div> {% endfor %} <div class="form-group"> <label for="avatar"> 头像 <img id="avatar_img" width="60px" height="60px" src="/static/blog/img/default.png" alt=""> </label> <input type="file" id="avatar" name="avatar"> </div> <input type="button" class="btn btn-default reg_btn" value="提交"> </form> </div> </div> </div> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <!--编写js代码--> <script> $("#avatar").change(function () { //1、获取用户选中的文件对象； var file_obj = $(this)[0].files[0]; //2、获取文件对象的路径； var reader = new FileReader(); reader.readAsDataURL(file_obj); //3、修改img的src属性值，src= 文件对象的路径； reader.onload = function(){ $("#avatar_img").attr("src",reader.result) }; }); //基于Ajax提交事件； $(".reg_btn").click(function () { var formdata = new FormData(); console.log($("#form").serializeArray()); var request_data = $("#form").serializeArray(); $.each(request_data,function (index,data) { formdata.append(data.name,data.value) }); formdata.append("avatar",$("#avatar")[0].files[0]); /* var formdata = new FormData(); formdata.append("user",$("#id_user").val()); formdata.append("pwd",$("#id_pwd").val()); formdata.append("r_pwd",$("#id_r_pwd").val()); formdata.append("email",$("#id_email").val()); formdata.append("avatar",$("#avatar")[0].files[0]); formdata.append("csrfmiddlewaretoken",$("[name = 'csrfmiddlewaretoken']").val());*/ $.ajax({ url:"", type:"post", contentType:false, processData:false, data:formdata, success:function (data) { console.log(data); if(data.user){ //注册成功； }else {//注册失败 //console.log(data.msg) //清空错误提示消息； $("span.error").html(); $(".form-group").removeClass("has-error"); //展示此次提提交的信息； $.each(data.msg,function (field,error_list) { console.log(field,error_list); if(field=="__all__"){ $("#id_r_pwd").next().html(error_list[0]).parent().addClass("has-error") } $("#id_"+field).next().html(error_list[0]); $("#id_"+field).parent().addClass("has-error"); }) } } }); }); </script> </body> </html>
25-博客系统之FileFiled字段
1、先导入from blog.models import UserInfo；
2、is_valid()校验通过后，向数据库库中写入数据，注意此时使用的是，UserInfo.objects.create_user()方法进行写入数据；
3、进行注册功能的验证；
4、进行登录验证；
26-博客系统之media配置1
1、settings.py中，STATICFILES_DIRS、MEDIA_ROOT配置；
2、上传文件，default的逻辑判断；
from django.shortcuts import render,HttpResponse,redirect # Create your views here. from django.http import JsonResponse from django.contrib import auth def login(request): """ 登录； :param request: :return: """ if request.method == "POST": response = {"user":None,"msg":None} user = request.POST.get("user") pwd = request.POST.get("pwd") valid_code = request.POST.get("valid_code") valid_code_str = request.session.get("valid_code_str") if valid_code.upper() == valid_code_str.upper(): user = auth.authenticate(username = user,password = pwd) if user: response["user"] = user.username else: response["msg"] = "用户名或者密码错误！" else: response["msg"] = "验证码错误!" return JsonResponse(response) return render(request,"login.html") def get_valid_code_img(request): """ 基于PIL模块动态生成响应状态码图片； :param request: :return: """ from blog.utils.validCode import get_valid_code_img data = get_valid_code_img(request) return HttpResponse(data) def index(request): """ 首页； :param request: :return: """ return render(request,"index.html") from blog.Myforms import UserForm from blog.models import UserInfo def register(request): """ 注册； :param request: :return: """ #if request.method == "POST": if request.is_ajax(): print(request.POST) form = UserForm(request.POST) response = {"user":None,"msg":None} if form.is_valid(): response["user"] = form.cleaned_data.get("user") #生成一条用户记录； user = form.cleaned_data.get("user") pwd = form.cleaned_data.get("pwd") email = form.cleaned_data.get("email") avatar_obj = request.FILES.get("avatar") if avatar_obj: user_obj = UserInfo.objects.create_user(username=user,password=pwd,email=email,avatar = avatar_obj ) else: user_obj = UserInfo.objects.create_user(username=user, password=pwd, email=email) else: print(form.cleaned_data) print(form.errors) response["msg"] = form.errors return JsonResponse(response) form = UserForm() return render(request,"register.html",{"form":form})
27-博客系统之media配置2
1、settings.py中MEDIAZ_URL的配置；
2、urls.py中MEDIA_ROOT的引用而不是MEDIA_URL；
28-博客系统之生成用户对象的代码优化
1、减少冗余代码，提高可读性；
from django.shortcuts import render, HttpResponse, redirect # Create your views here. from django.http import JsonResponse from django.contrib import auth from blog.Myforms import UserForm from blog.models import UserInfo def login(request): """ 登录； :param request: :return: """ if request.method == "POST": response = {"user": None, "msg": None} user = request.POST.get("user") pwd = request.POST.get("pwd") valid_code = request.POST.get("valid_code") valid_code_str = request.session.get("valid_code_str") if valid_code.upper() == valid_code_str.upper(): user = auth.authenticate(username=user, password=pwd) if user: response["user"] = user.username else: response["msg"] = "用户名或者密码错误！" else: response["msg"] = "验证码错误!" return JsonResponse(response) return render(request, "login.html") def get_valid_code_img(request): """ 基于PIL模块动态生成响应状态码图片； :param request: :return: """ from blog.utils.validCode import get_valid_code_img data = get_valid_code_img(request) return HttpResponse(data) def index(request): """ 首页； :param request: :return: """ return render(request, "index.html") def register(request): """ 注册； :param request: :return: """ # if request.method == "POST": if request.is_ajax(): # print(request.POST) form = UserForm(request.POST) response = {"user": None, "msg": None} if form.is_valid(): response["user"] = form.cleaned_data.get("user") # 生成一条用户记录； user = form.cleaned_data.get("user") pwd = form.cleaned_data.get("pwd") email = form.cleaned_data.get("email") avatar_obj = request.FILES.get("avatar") ''' if avatar_obj: user_obj = UserInfo.objects.create_user(username=user,password=pwd,email=email,avatar = avatar_obj ) else: user_obj = UserInfo.objects.create_user(username=user, password=pwd, email=email) ''' extra = {} if avatar_obj: extra["avatar"] = avatar_obj UserInfo.objects.create_user(username=user, password=pwd, email=email, ) else: # print(form.cleaned_data) # print(form.errors) response["msg"] = form.errors return JsonResponse(response) form = UserForm() return render(request, "register.html", {"form": form})
2、import使用方式，一般位于py文件的顶部且有顺序，先xx后xx；
Pycharm中，使用Ctrl+Shift+L组合键，进行Reformat Code操作，提升代码排版规范；
3、遵循PEP8代码编写规范，提高代码质量；
Python语言规范；https://zh-google-styleguide.readthedocs.io/en/latest/google-python-styleguide/python_language_rules/
29-博客系统之系统首页的导航区域
1、Bootstrap之导航条的使用；
2、{{ request.user.username }}的使用；
3、auth.logout(request) # 等同于request.session.flush()；

30-博客系统之系统首页的主体布局
1、基于Bootstrap的格栅系统，定制页面布局；
<!--引入BootStrap格栅系统--> <div class="container-fluid"> <div class="row"> <div class="col-md-3"> <div class="panel panel-warning"> <div class="panel-heading">Panel heading without title</div> <div class="panel-body"> Panel content </div> </div> <div class="panel panel-info"> <div class="panel-heading">Panel heading without title</div> <div class="panel-body"> Panel content </div> </div> <div class="panel panel-danger"> <div class="panel-heading">Panel heading without title</div> <div class="panel-body"> Panel content </div> </div> </div> <div class="col-md-6">222</div> <div class="col-md-3"> <div class="panel panel-default"> <div class="panel-heading">Panel heading without title</div> <div class="panel-body"> Panel content </div> </div> <div class="panel panel-primary"> <div class="panel-heading">Panel heading without title</div> <div class="panel-body"> Panel content </div> </div> <div class="panel panel-default"> <div class="panel-heading">Panel heading without title</div> <div class="panel-body"> Panel content </div> </div> </div> </div> </div>
31-博客系统之admin的简单实用
1、Django下的admin初识；
Django内部的一个组件：后台数据管理组件（Web界面）；
创建超级用户的方法：python manage.py createsuperuser 针对用户认证，在blog_userinfo表中生成记录，is_super字段值为1；
2、settings.py中的admin说明；
3、基于应用名称的blog中的admin.py进行表的注册；
from django.contrib import admin # Register your models here. from blog import models admin.site.register(models.UserInfo) admin.site.register(models.Blog) admin.site.register(models.Category) admin.site.register(models.Tag) admin.site.register(models.Article) admin.site.register(models.ArticleUpDown) admin.site.register(models.Article2Tag) admin.site.register(models.Comment)
32-博客系统之基于admin录入文章数据
1、通过Web前端页面进行文章数据的录入；

1、以年和月的格式显示；
date_list = models.Article.objects.filter(user=user).extra(select={"y_m_date":"date_format(create_time,'%%Y-%%m')"}).values("y_m_date").annotate(c = Count("nid")).values("y_m_date","c")
print("这里是date_list",date_list)
40-博客系统之个人站点页面的日期查询4
1、使用Django内置的TruncMonth代理extra()方法以及date_format；

41-博客系统之个人站点页面的渲染布局1
1、顶部导航栏设置，右浮动设置；
2、基于博客的title向页面渲染数据；
home_site.html;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home_site</title> <style type="text/css"> * { margin: 0; padding: 0; } .header { width: 100%; height: 60px; background-color: #369; } .header .title { font-size: 18px; font-weight: 100; line-height: 60px; color: white; margin-left: 15px; margin-top: -10px; } .backend{ float: right; color: white; text-decoration: none; font-size: 14px; margin-right: 10px; margin-top: 10px; } </style> </head> <body> <div class="header"> <div class="content"> <p class="title"> <span>{{ blog.title }}</span> <a href="" class="backend">管理</a> </p> </div> </div> </body> </html>
42-博客系统之个人站点页面的渲染布局2
1、站点页面的格栅系统布局渲染；
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home_site</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <script src="/static/blog/bs/js/bootstrap.min.js"></script> <style type="text/css"> * { margin: 0; padding: 0; } .header { width: 100%; height: 60px; background-color: #369; } .header .title { font-size: 18px; font-weight: 100; line-height: 60px; color: white; margin-left: 15px; margin-top: -10px; } .backend { float: right; color: white; text-decoration: none; font-size: 14px; margin-right: 10px; margin-top: 10px; } .pub_info { margin-top: 10px; color: darkgray; } </style> </head> <body> <div class="header"> <div class="content"> <p class="title"> <span>{{ blog.title }}</span> <a href="" class="backend">管理</a> </p> </div> </div> <div class="container"> <div class="row"> <div class="col-md-3"> </div> <div class="col-md-9"> <div class="article_list"> {% for article in article_list %} <div class="article-item clearfix"> <h5><a href="">{{ article.title }}</a></h5> <div class="article-desc"> {{ article.desc }} </div> </div> <div class="small pub_info pull-right"> <span>发布于 {{ article.create_time|date:"Y-m-d H:i" }}</span> <span class="glyphicon glyphicon-comment"></span>评论({{ article.comment_count }}) <span class="glyphicon glyphicon-thumbs-up"></span>点赞({{ article.up_count }}) </div> <hr> {% endfor %} </div> </div> </div> </div> </body> </html>
43-博客系统之个人站点页面的渲染布局3
1、在Bootstrap的栅格系统col-md-3左侧栏设置“我的标签”、“随笔分类”、“随笔归档”等分类tag；
<div class="col-md-3"> <div class="panel panel-warning"> <div class="panel-heading">我的标签</div> <div class="panel-body"> {% for tag in tag_list %} <p>{{ tag.0 }}({{ tag.1 }})</p> {% endfor %} </div> </div> <div class="panel panel-danger"> <div class="panel-heading">随笔分类</div> <div class="panel-body"> {% for cate in cate_list %} <p>{{ cate.0 }}({{ cate.1 }})</p> {% endfor %} </div> </div> <div class="panel panel-success"> <div class="panel-heading">随笔归档</div> <div class="panel-body"> {% for date in date_list %} <p>{{ date.0 }}({{ date.1 }})</p> {% endfor %} </div> </div> </div>
2、通过数据库进行渲染的到数据并循环进行前端展示；
views.py;
def home_site(request, username, **kwargs): """ 个人站点视图函数 :param request: :return: """ print("kwargs", kwargs) # 区分访问是的站点页面还是站点下的跳转页面 print("username", username) user = UserInfo.objects.filter(username=username).first() # 判断用户是否存在! if not user: return render(request, "not_found.html") # 查询当前站点对象 blog = user.blog # 1 当前用户或者当前站点对应所有文章 # 基于对象查询 # article_list=user.article_set.all() # 基于 __ article_list = models.Article.objects.filter(user=user) if kwargs: condition = kwargs.get("condition") param = kwargs.get("param") # 2012-12 if condition == "category": article_list = article_list.filter(category__title=param) elif condition == "tag": article_list = article_list.filter(tags__title=param) else: year, month = param.split("/") article_list = article_list.filter(create_time__year=year, create_time__month=month) # 每一个后的表模型.objects.values("pk").annotate(聚合函数(关联表__统计字段)).values("表模型的所有字段以及统计字段") # 查询每一个分类名称以及对应的文章数 # ret=models.Category.objects.values("pk").annotate(c=Count("article__title")).values("title","c") # print(ret) # 查询当前站点的每一个分类名称以及对应的文章数 cate_list = models.Category.objects.filter(blog=blog).values("pk").annotate(c=Count("article__title")).values_list( "title", "c") print(cate_list) # 查询当前站点的每一个标签名称以及对应的文章数 tag_list = models.Tag.objects.filter(blog=blog).values("pk").annotate(c=Count("article")).values_list("title", "c") print(tag_list) # 查询当前站点每一个年月的名称以及对应的文章数 # ret=models.Article.objects.extra(select={"is_recent":"create_time > '2018-09-05'"}).values("title","is_recent") # print(ret) # 方式1: date_list = models.Article.objects.filter(user=user).extra( select={"y_m_date": "date_format(create_time,'%%Y/%%m')"}).values("y_m_date").annotate( c=Count("nid")).values_list("y_m_date", "c") print(date_list) # 方式2: # from django.db.models.functions import TruncMonth # # ret=models.Article.objects.filter(user=user).annotate(month=TruncMonth("create_time")).values("month").annotate(c=Count("nid")).values_list("month","c") # print("ret----->",ret) return render(request, "home_site.html", {"username": username, "blog": blog, "article_list": article_list, "tag_list": tag_list, "cate_list": cate_list,"date_list":date_list})
3、展示效果如图所示；
44-博客系统之个人站点的跳转过滤功能的实现1
1、urls.py之路由设计，添加有名分组；
"""cnblogs URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/2.1/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.contrib import admin from django.urls import path, re_path from blog import views from django.views.static import serve from cnblogs import settings urlpatterns = [ path('admin/', admin.site.urls), path('login/', views.login), path('index/', views.index), path('logout/', views.logout), re_path('^$', views.index), path('get_validCode_img/', views.get_valid_code_img), path('register/', views.register), # media配置； re_path(r'media/(?P<path>.*)$', serve, {"document_root": settings.MEDIA_ROOT}), # 个人站点URL； re_path(r'^(?P<username>\w+)/(?P<condition>tag|category|archive)/(?P<param>.*)/$', views.home_site), #re_path(r'^(?P<username>\w+)/category/.*/$', views.home_site), #re_path(r'^(?P<username>\w+)/archive/.*/$', views.home_site), re_path(r'^(?P<username>\w+)$', views.home_site), ]
45-博客系统之个人站点页面的跳转过滤功能实现2
1、urls.py中，针对于相同视图函数匹配不同的路径，需要传入不同的参数的解决办法；
"""cnblogs URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/2.1/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.contrib import admin from django.urls import path, re_path from blog import views from django.views.static import serve from cnblogs import settings urlpatterns = [ path('admin/', admin.site.urls), path('login/', views.login), path('index/', views.index), path('logout/', views.logout), re_path('^$', views.index), path('get_validCode_img/', views.get_valid_code_img), path('register/', views.register), # media配置； re_path(r'media/(?P<path>.*)$', serve, {"document_root": settings.MEDIA_ROOT}), # 个人站点下的跳转URL；# 接受的参数，home_site(request,username,condition,param) re_path(r'^(?P<username>\w+)/(?P<condition>tag|category|archive)/(?P<param>.*)/$', views.home_site), # re_path(r'^(?P<username>\w+)/category/.*/$', views.home_site), # re_path(r'^(?P<username>\w+)/archive/.*/$', views.home_site), # 个人站点URL；#接收的参数home_site(request,username="cxz") re_path(r'^(?P<username>\w+)/$', views.home_site), ]
2、MySQL数据库针对于create_time有约束的限制，需调整settings.py中的USE_TZ = True改为False；
3、针对于年和月的匹配规则，使用split()方法进行分割处理；
def home_site(request, username, **kwargs): """ 个人站点视图函数 :param request: :return: """ print("kwargs", kwargs) # 区分访问是的站点页面还是站点下的跳转页面； print("username", username) user = UserInfo.objects.filter(username=username).first() # 判断用户是否存在! if not user: return render(request, "not_found.html") # 查询当前站点对象 blog = user.blog # 1 当前用户或者当前站点对应所有文章 # 基于对象查询 # article_list=user.article_set.all() # 基于 __ article_list = models.Article.objects.filter(user=user) if kwargs: condition = kwargs.get("condition") param = kwargs.get("param") # 2012-12 if condition == "category": article_list = article_list.filter(category__title=param) elif condition == "tag": article_list = article_list.filter(tags__title=param) else: year, month = param.split("/") article_list = article_list.filter(create_time__year=year, create_time__month=month) # 每一个后的表模型.objects.values("pk").annotate(聚合函数(关联表__统计字段)).values("表模型的所有字段以及统计字段") # 查询每一个分类名称以及对应的文章数 # ret=models.Category.objects.values("pk").annotate(c=Count("article__title")).values("title","c") # print(ret) # 查询当前站点的每一个分类名称以及对应的文章数 cate_list = models.Category.objects.filter(blog=blog).values("pk").annotate(c=Count("article__title")).values_list( "title", "c") print(cate_list) # 查询当前站点的每一个标签名称以及对应的文章数 tag_list = models.Tag.objects.filter(blog=blog).values("pk").annotate(c=Count("article")).values_list("title", "c") print(tag_list) # 查询当前站点每一个年月的名称以及对应的文章数 # ret=models.Article.objects.extra(select={"is_recent":"create_time > '2018-09-05'"}).values("title","is_recent") # print(ret) # 方式1: date_list = models.Article.objects.filter(user=user).extra( select={"y_m_date": "date_format(create_time,'%%Y-%%m')"}).values("y_m_date").annotate( c=Count("nid")).values_list("y_m_date", "c") print(date_list) # 方式2: # from django.db.models.functions import TruncMonth # # ret=models.Article.objects.filter(user=user).annotate(month=TruncMonth("create_time")).values("month").annotate(c=Count("nid")).values_list("month","c") # print("ret----->",ret) return render(request, "home_site.html", {"username": username, "blog": blog, "article_list": article_list, "tag_list": tag_list, "cate_list": cate_list,"date_list":date_list})
46-博客系统之个人站点页面的跳转过滤功能的实现3
1、基于“我的标签”、“随笔分类”、“随笔归档”进行跳转；

47-博客系统之文章详情页的设计
1、路由urls.py配置；
re_path(r'^(?P<username>\w+)/articles/(?P<article_id>\d+)$', views.article_detail),
48-博客系统之文章详情页的构建
1、进行程序解耦合操作，分离base.html，基于{% extends 'base.html' %}进行调用;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home_site</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <script src="/static/blog/bs/js/bootstrap.min.js"></script> <style type="text/css"> * { margin: 0; padding: 0; } .header { width: 100%; height: 60px; background-color: #369; } .header .title { font-size: 18px; font-weight: 100; line-height: 60px; color: white; margin-left: 15px; margin-top: -10px; } .backend { float: right; color: white; text-decoration: none; font-size: 14px; margin-right: 10px; margin-top: 10px; } .pub_info { margin-top: 10px; color: darkgray; } </style> </head> <body> <div class="header"> <div class="content"> <p class="title"> <span>{{ blog.title }}</span> <a href="" class="backend">管理</a> </p> </div> </div> <div class="container"> <div class="row"> <div class="col-md-3"> <div class="panel panel-warning"> <div class="panel-heading">我的标签</div> <div class="panel-body"> {% for tag in tag_list %} <p><a href="/{{ username }}/tag/{{ tag.0 }}"> {{ tag.0 }}({{ tag.1 }})</a></p> {% endfor %} </div> </div> <div class="panel panel-danger"> <div class="panel-heading">随笔分类</div> <div class="panel-body"> {% for cate in cate_list %} <p><a href="/{{ username }}/category/{{ cate.0 }}"> {{ cate.0 }}({{ tag.1 }})</a></p> {% endfor %} </div> </div> <div class="panel panel-success"> <div class="panel-heading">随笔归档</div> <div class="panel-body"> {% for date in date_list %} <p><a href="/{{ username }}/archive/{{ date.0 }}"> {{ date.0 }}({{ tag.1 }})</a></p> {% endfor %} </div> </div> </div> <div class="col-md-9"> {% block content %} {% endblock %} </div> </div> </div> </body> </html>
2、生成article_detail.html;
{% extends 'base.html' %}
3、重用的代码优化，编写独立函数进行调用；
from django.shortcuts import render, HttpResponse, redirect # Create your views here. from django.http import JsonResponse from django.contrib import auth from blog.Myforms import UserForm from blog.models import UserInfo from blog import models from django.db.models import Count def login(request): """ 登录； :param request: :return: """ if request.method == "POST": response = {"user": None, "msg": None} user = request.POST.get("user") pwd = request.POST.get("pwd") valid_code = request.POST.get("valid_code") valid_code_str = request.session.get("valid_code_str") if valid_code.upper() == valid_code_str.upper(): user = auth.authenticate(username=user, password=pwd) if user: auth.login(request, user) response["user"] = user.username else: response["msg"] = "用户名或者密码错误！" else: response["msg"] = "验证码错误!" return JsonResponse(response) return render(request, "login.html") def index(request): """ 首页； :param request: :return: """ article_list = models.Article.objects.all() return render(request, "index.html", {"article_list": article_list}) def logout(request): auth.logout(request) # 等同于request.session.flush() return redirect("/login/") def get_valid_code_img(request): """ 基于PIL模块动态生成响应状态码图片； :param request: :return: """ from blog.utils.validCode import get_valid_code_img data = get_valid_code_img(request) return HttpResponse(data) def register(request): """ 注册； :param request: :return: """ # if request.method == "POST": if request.is_ajax(): # print(request.POST) form = UserForm(request.POST) response = {"user": None, "msg": None} if form.is_valid(): response["user"] = form.cleaned_data.get("user") # 生成一条用户记录； user = form.cleaned_data.get("user") pwd = form.cleaned_data.get("pwd") email = form.cleaned_data.get("email") avatar_obj = request.FILES.get("avatar") ''' if avatar_obj: user_obj = UserInfo.objects.create_user(username=user,password=pwd,email=email,avatar = avatar_obj ) else: user_obj = UserInfo.objects.create_user(username=user, password=pwd, email=email) ''' extra = {} if avatar_obj: extra["avatar"] = avatar_obj UserInfo.objects.create_user(username=user, password=pwd, email=email, **extra) else: # print(form.cleaned_data) # print(form.errors) response["msg"] = form.errors return JsonResponse(response) form = UserForm() return render(request, "register.html", {"form": form}) def get_query_data(username): user = UserInfo.objects.filter(username=username).first() # 判断用户是否存在!

49-博客系统之文章详情页的inclution_tag
1、配置base.html;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home_site</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <script src="/static/blog/bs/js/bootstrap.min.js"></script> <style type="text/css"> * { margin: 0; padding: 0; } .header { width: 100%; height: 60px; background-color: #369; } .header .title { font-size: 18px; font-weight: 100; line-height: 60px; color: white; margin-left: 15px; margin-top: -10px; } .backend { float: right; color: white; text-decoration: none; font-size: 14px; margin-right: 10px; margin-top: 10px; } .pub_info { margin-top: 10px; color: darkgray; } </style> </head> <body> <div class="header"> <div class="content"> <p class="title"> <span>{{ blog.title }}</span> <a href="" class="backend">管理</a> </p> </div> </div> <div class="container"> <div class="row"> <div class="col-md-3 menu"> {% load my_tags %} {% get_classification_style username %} </div> <div class="col-md-9"> {% block content %} {% endblock %} </div> </div> </div> </body> </html>
2、引入自定义标签templatetags；
3、使用register.inclusion_tag("classification.html")
# @register.simple_tag @register.inclusion_tag("classification.html") def get_classification_style(username): user = models.UserInfo.objects.filter(username=username).first() # 查询当前站点对象 blog = user.blog # 查询当前站点的每一个分类名称以及对应的文章数 cate_list = models.Category.objects.filter(blog=blog).values("pk").annotate(c=Count("article__title")).values_list( "title", "c") tag_list = models.Tag.objects.filter(blog=blog).values("pk").annotate(c=Count("article")).values_list("title", "c") date_list = models.Article.objects.filter(user=user).extra( select={"y_m_date": "date_format(create_time,'%%Y-%%m')"}).values("y_m_date").annotate( c=Count("nid")).values_list("y_m_date", "c") return {"blog": blog, "cate_list": cate_list, "date_list": date_list, "tag_list": tag_list}
4、总体来讲，降低程序耦合度，提高可拓展性；
<div> <div class="panel panel-warning"> <div class="panel-heading">我的标签</div> <div class="panel-body"> {% for tag in tag_list %} <p><a href="/{{ username }}/tag/{{ tag.0 }}"> {{ tag.0 }}({{ tag.1 }})</a></p> {% endfor %} </div> </div> <div class="panel panel-danger"> <div class="panel-heading">随笔分类</div> <div class="panel-body"> {% for cate in cate_list %} <p><a href="/{{ username }}/category/{{ cate.0 }}"> {{ cate.0 }}({{ tag.1 }})</a></p> {% endfor %} </div> </div> <div class="panel panel-success"> <div class="panel-heading">随笔归档</div> <div class="panel-body"> {% for date in date_list %} <p><a href="/{{ username }}/archive/{{ date.0 }}"> {{ date.0 }}({{ tag.1 }})</a></p> {% endfor %} </div> </div> </div>
50-博客系统之文章详情页渲染标签的标签字符串转义1
1、Django内部将标签字符串做了转义处理；
2、article_detail.html;
{% extends 'base.html' %} {% block content %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content }} </div> {% endblock %}
51-博客系统之文章详情页渲染的标签字符串转义2
1、设置safe属性，防止xss攻击；
2、article_detail.html;
{% extends 'base.html' %} {% block content %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> {% endblock %}
52-博客系统之文章点赞样式的构建
1、点赞的样式仿照博客园进行构建，并且拆分独立css样式文件，使用link方法进行引入；
article_detail.html;
{% extends 'base.html' %} {% block content %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> <div id="div_digg"> <div class="diggit"> <span class="diggnum" id="digg_count">1</span> </div> <div class="buryit"> <span class="burynum" id="bury_count">0</span> </div> <div class="clear"></div> <div class="diggword" id="digg_tips" style="color:red;"></div> </div> {% endblock %}
home_site.css;
* {
margin: 0;
padding: 0;
}
.header {
width: 100%;
height: 60px;
background-color: #369;
}
.header .title {
font-size: 18px;
font-weight: 100;
line-height: 60px;
color: white;
margin-left: 15px;
margin-top: -10px;
}
.backend {
float: right;
color: white;
text-decoration: none;
font-size: 14px;
margin-right: 10px;
margin-top: 10px;
}
.pub_info {
margin-top: 10px;
color: darkgray;
}
article_detail.css;
.article_info .title {
margin-bottom: 20px;
}
#div_digg {
float: right;
margin-bottom: 10px;
margin-right: 30px;
font-size: 12px;
width: 125px;
text-align: center;
margin-top: 10px;
}
.diggit {
float: left;
width: 46px;
height: 52px;
background: url(/static/blog/img/upup.gif) no-repeat;
text-align: center;
cursor: pointer;
margin-top: 2px;
padding-top: 5px;
}
.buryit {
float: right;
margin-left: 20px;
width: 46px;
height: 52px;
background: url(/static/blog/img/downdown.gif) no-repeat;
text-align: center;
cursor: pointer;
margin-top: 2px;
padding-top: 5px;
}
.clear{
clear: both;
}
53-博客系统之文章点赞事件的绑定
1、base.html引入本地静态jQuery文件；
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home_site</title> <link rel="stylesheet" href="/static/blog/bs/css/bootstrap.css"> <script src="/static/blog/js/jquery-3.3.1.min.js"></script> <script src="/static/blog/bs/js/bootstrap.min.js"></script> <link rel="stylesheet" href="/static/blog/css/home_site.css"> <link rel="stylesheet" href="/static/blog/css/article_detail.css"> </head>
2、article_detail.html添加js事件；
{% extends 'base.html' %} {% block content %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> <div id="div_digg"> <div class="diggit action"> <span class="diggnum" id="digg_count">1</span> </div> <div class="buryit action"> <span class="burynum" id="bury_count">0</span> </div> <div class="clear"></div> <div class="diggword" id="digg_tips" style="color:red;"></div> </div> <script> $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit") alert(is_up) }) </script> {% endblock %}
54-博客系统之文章点赞的保存
1、绑定Ajax事件；
{% extends 'base.html' %}
{% block content %}
{% csrf_token %}
<h3 class="text-center">{{ article_obj.title }}</h3>
<div class="cont">
{{ article_obj.content|safe }}
</div>
<div id="div_digg">
<div class="diggit action">
<span class="diggnum" id="digg_count">{{ article_obj.up_count }}</span>
</div>
<div class="buryit action">
<span class="burynum" id="bury_count">{{ article_obj.down_count }}</span>
</div>
<div class="clear"></div>
<div class="diggword" id="digg_tips" style="color:red;"></div>
</div>
<script>
$("#div_digg .action").click(function () {
var is_up = $(this).hasClass("diggit");
alert(is_up)
//传Ajax事件；
$.ajax({
url: "/digg/",
type: "post",
data: {
"csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(),
"is_up": is_up,
"article_id": "{{ article_obj.pk }}",
},
success: function (data) {
console.log(data)
}
})
});
</script>
{% endblock %}
2、基于digg视图函数进行数据的添加；
def digg(request): """ 点赞视图函数； :param request: :return: """ print(request.POST) article_id = request.POST.get("article_id") is_up = json.loads(request.POST.get("is_up")) # 点赞人即当前登录人； user_id = request.user.pk ard = models.ArticleUpDown.objects.create(user_id=user_id, article_id=article_id, is_up=is_up) return HttpResponse("ok")
3、新增urls.py下的digg视图；
"""cnblogs URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/2.1/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.contrib import admin from django.urls import path, re_path from blog import views from django.views.static import serve from cnblogs import settings urlpatterns = [ path('admin/', admin.site.urls), path('login/', views.login), path('index/', views.index), path('logout/', views.logout), re_path('^$', views.index), path('get_validCode_img/', views.get_valid_code_img), path('register/', views.register), path('digg/', views.digg), # media配置； re_path(r'media/(?P<path>.*)$', serve, {"document_root": settings.MEDIA_ROOT}), re_path(r'^(?P<username>\w+)/articles/(?P<article_id>\d+)$', views.article_detail), # 个人站点下的跳转URL；# 接受的参数，home_site(request,username,condition,param) re_path(r'^(?P<username>\w+)/(?P<condition>tag|category|archive)/(?P<param>.*)/$', views.home_site), # re_path(r'^(?P<username>\w+)/category/.*/$', views.home_site), # re_path(r'^(?P<username>\w+)/archive/.*/$', views.home_site), # 个人站点URL；#接收的参数home_site(request,username="cxz") re_path(r'^(?P<username>\w+)/$', views.home_site), ]
55-博客系统之文章点赞数的数据同步
1、通过update方法像数据库中新增数据；
def digg(request): """ 点赞视图函数； :param request: :return: """ print(request.POST) article_id = request.POST.get("article_id") is_up = json.loads(request.POST.get("is_up")) # 点赞人即当前登录人； user_id = request.user.pk ard = models.ArticleUpDown.objects.create(user_id=user_id, article_id=article_id, is_up=is_up) if is_up: models.Article.objects.filter(pk=article_id).update(up_count=F("up_count") + 1) return HttpResponse("ok")
56-博客系统之文章点赞的提示重复操作
1、评论与点赞只允许一次的逻辑以及提示消息；
def digg(request): """ 点赞视图函数； :param request: :return: """ print(request.POST) article_id = request.POST.get("article_id") is_up = json.loads(request.POST.get("is_up")) # 点赞、点踩的人即当前登录人； user_id = request.user.pk obj = models.ArticleUpDown.objects.filter(user_id=user_id, article_id=article_id).first() response = {"state": True} if not obj: ard = models.ArticleUpDown.objects.create(user_id=user_id, article_id=article_id, is_up=is_up) queryset = models.Article.objects.filter(pk=article_id) if is_up: queryset.update(up_count=F("up_count") + 1) else: queryset.update(down_count=F("down_count") + 1) else: response["state"] = False response["handled"] = obj.is_up return JsonResponse(response)
2、前端js代码的业务逻辑；
<script> $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit"); // alert(is_up) //传Ajax事件； $.ajax({ url: "/digg/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "is_up": is_up, "article_id": "{{ article_obj.pk }}", }, success: function (data) { console.log(data); if (data.state){ }else { if (data.handled){ $("#digg_tips").html("您已经推荐过！") }else{ $("#digg_tips").html("您已经反对过！") } setTimeout(function () { $("#digg_tips").html("") },1000) } } }) }); </script>
57-博客系统之文章点赞数的Ajax更新
1、点赞功能的局部刷新功能；
<script> $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit"); // alert(is_up) //传Ajax事件； $.ajax({ url: "/digg/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "is_up": is_up, "article_id": "{{ article_obj.pk }}", }, success: function (data) { console.log(data); if (data.state) { if (is_up) { var val = parseInt($("#digg_count").text()); $("#digg_count").text(val + 1); } else { var val = parseInt($("#bury_count").text()); $("#bury_count").text(val + 1); } } else { if (data.handled) { $("#digg_tips").html("您已经推荐过！") } else { $("#digg_tips").html("您已经反对过！") } setTimeout(function () { $("#digg_tips").html("") }, 1000) } } }) }); </script>
58-博客系统之文章点赞代码的优化
1、减少重复代码，提高程序精简性；
2、三元运算以及$obj = $(this).children("span")的使用;
{% extends 'base.html' %} {% block content %} {% csrf_token %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> <div id="div_digg"> <div class="diggit action"> <span class="diggnum" id="digg_count">{{ article_obj.up_count }}</span> </div> <div class="buryit action"> <span class="burynum" id="bury_count">{{ article_obj.down_count }}</span> </div> <div class="clear"></div> <div class="diggword" id="digg_tips" style="color:red;"></div> </div> <script> $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit"); // alert(is_up) //传Ajax事件； $obj = $(this).children("span"); $.ajax({ url: "/digg/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "is_up": is_up, "article_id": "{{ article_obj.pk }}", }, success: function (data) { console.log(data); if (data.state) { var val = parseInt($("#digg_count").text()); $obj.text(val + 1); } else { var val = data.handled ? "您已经推荐过！" : "您已经反对过！"; $("#digg_tips").html(val); setTimeout(function () { $("#digg_tips").html("") }, 1000) } } }) }); </script> {% endblock %}
59-博客系统之评论功能的实现流程
1、评论功能设计思路；
60-博客系统之评论样式
1、评论功能样式确定；
article_detail.html;
{% extends 'base.html' %} {% block content %} {% csrf_token %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> <div class="clearfix"> <div id="div_digg"> <div class="diggit action"> <span class="diggnum" id="digg_count">{{ article_obj.up_count }}</span> </div> <div class="buryit action"> <span class="burynum" id="bury_count">{{ article_obj.down_count }}</span> </div> <div class="clear"></div> <div class="diggword" id="digg_tips" style="color:red;"></div> </div> </div> <div class="commonts"> <p>发表评论</p> <p> 昵称：<input type="text" id="tbCommentAuthor" class="author" disabled="disabled" size="50" value="{{ request.user.username }}"> </p> <p>评论内容:</p> <textarea name="" id="" cols="60" rows="10"></textarea> <p> <button class="btn btn-default common_btn">提交评论</button> </p> </div> <script> $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit"); // alert(is_up) //传Ajax事件； $obj = $(this).children("span"); $.ajax({ url: "/digg/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "is_up": is_up, "article_id": "{{ article_obj.pk }}", }, success: function (data) { console.log(data); if (data.state) { var val = parseInt($("#digg_count").text()); $obj.text(val + 1); } else { var val = data.handled ? "您已经推荐过！" : "您已经反对过！"; $("#digg_tips").html(val); setTimeout(function () { $("#digg_tips").html("") }, 1000) } } }) }); </script> {% endblock %}
2、评论功能组件设置之——发表评论、昵称（动态引用）、评论头像、评论内容、提交评论；
61-博客系统之提交根评论
1、提交评论&保存评论；
2、清除评论框操作；
{% extends 'base.html' %} {% block content %} {% csrf_token %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> <div class="clearfix"> <div id="div_digg"> <div class="diggit action"> <span class="diggnum" id="digg_count">{{ article_obj.up_count }}</span> </div> <div class="buryit action"> <span class="burynum" id="bury_count">{{ article_obj.down_count }}</span> </div> <div class="clear"></div> <div class="diggword" id="digg_tips" style="color:red;"></div> </div> </div> <div class="commonts"> <p>发表评论</p> <p> 昵称：<input type="text" id="tbCommentAuthor" class="author" disabled="disabled" size="50" value="{{ request.user.username }}"> </p> <p>评论内容:</p> <textarea name="" id="comment_content" cols="60" rows="10"></textarea> <p> <button class="btn btn-default common_btn">提交评论</button> </p> </div> <script> //点赞请求； $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit"); // alert(is_up) //传Ajax事件； $obj = $(this).children("span"); $.ajax({ url: "/digg/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "is_up": is_up, "article_id": "{{ article_obj.pk }}", }, success: function (data) { console.log(data); if (data.state) { var val = parseInt($("#digg_count").text()); $obj.text(val + 1); } else { var val = data.handled ? "您已经推荐过！" : "您已经反对过！"; $("#digg_tips").html(val); setTimeout(function () { $("#digg_tips").html("") }, 1000) } } }) }); //评论请求； $(".common_btn").click(function () { var pid = ""; var content = $("#comment_content").val(); $.ajax({ url: "/comment/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "article_id": "{{ article_obj.pk }}", "content": content, pid:pid, }, success: function (data) { console.log(data); //清空评论框; $("#comment_content").val("") } }) }) </script> {% endblock %}
comment视图函数；
def comment(request): print(request.POST) article_id = request.POST.get("article_id") pid = request.POST.get("pid") content = request.POST.get("content") user_id = request.user.pk comment_obj = models.Comment.objects.create(user_id=user_id, article_id=article_id, content=content, parent_comment_id=pid) return HttpResponse("comment")
62-博客系统之render显示根评论
评论列表的render显示；
{% extends 'base.html' %} {% block content %} {% csrf_token %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> <div class="clearfix"> <div id="div_digg"> <div class="diggit action"> <span class="diggnum" id="digg_count">{{ article_obj.up_count }}</span> </div> <div class="buryit action"> <span class="burynum" id="bury_count">{{ article_obj.down_count }}</span> </div> <div class="clear"></div> <div class="diggword" id="digg_tips" style="color:red;"></div> </div> </div> <div class="commonts"> <p>评论列表</p> <ul class="list-group comment_list"> {% for comment in comment_list %} <li class="list-group-item"> <div> <a href="">#{{ forloop.counter }}楼</a> <span>{{ comment.create_time|date:"Y-m-d H:i" }}</span> <a href=""><span>{{ comment.user.username }}</span></a> <a href="" class="pull-right">回复</a> </div> <div class="comment_con"> <p>{{ comment.content }}</p> </div> </li> {% endfor %} </ul> <p>发表评论</p> <p> 昵称：<input type="text" id="tbCommentAuthor" class="author" disabled="disabled" size="50" value="{{ request.user.username }}"> </p> <p>评论内容:</p> <textarea name="" id="comment_content" cols="60" rows="10"></textarea> <p> <button class="btn btn-default common_btn">提交评论</button> </p> </div> <script> //点赞请求； $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit"); // alert(is_up) //传Ajax事件； $obj = $(this).children("span"); $.ajax({ url: "/digg/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "is_up": is_up, "article_id": "{{ article_obj.pk }}", }, success: function (data) { console.log(data); if (data.state) { var val = parseInt($("#digg_count").text()); $obj.text(val + 1); } else { var val = data.handled ? "您已经推荐过！" : "您已经反对过！"; $("#digg_tips").html(val); setTimeout(function () { $("#digg_tips").html("") }, 1000) } } }) }); //评论请求； $(".common_btn").click(function () { var pid = ""; var content = $("#comment_content").val(); $.ajax({ url: "/comment/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "article_id": "{{ article_obj.pk }}", "content": content, pid: pid, }, success: function (data) { console.log(data); //清空评论框; $("#comment_content").val("") } }) }) </script> {% endblock %}

3、comment视图函数；
def comment(request): print(request.POST) article_id = request.POST.get("article_id") pid = request.POST.get("pid") content = request.POST.get("content") user_id = request.user.pk comment_obj = models.Comment.objects.create(user_id=user_id, article_id=article_id, content=content, parent_comment_id=pid) response = {} response["create_time"] = comment_obj.create_time.strftime("%Y-%m-%d %X") response["username"] = request.user.username response["content"] = content return JsonResponse(response)
64-博客系统之回复按钮事件
1、点击“回复”按钮，光标自动跳转至回复栏；
2、回复的对象@形式出现；
{% extends 'base.html' %} {% block content %} {% csrf_token %} <h3 class="text-center">{{ article_obj.title }}</h3> <div class="cont"> {{ article_obj.content|safe }} </div> <div class="clearfix"> <div id="div_digg"> <div class="diggit action"> <span class="diggnum" id="digg_count">{{ article_obj.up_count }}</span> </div> <div class="buryit action"> <span class="burynum" id="bury_count">{{ article_obj.down_count }}</span> </div> <div class="clear"></div> <div class="diggword" id="digg_tips" style="color:red;"></div> </div> </div> <div class="commonts"> <p>评论列表</p> <ul class="list-group comment_list"> {% for comment in comment_list %} <li class="list-group-item"> <div> <a href="">#{{ forloop.counter }}楼</a> <span>{{ comment.create_time|date:"Y-m-d H:i" }}</span> <a href=""><span>{{ comment.user.username }}</span></a> <a class="pull-right reply_btn" username = "{{ comment.user.username }}" >回复</a> </div> <div class="comment_con"> <p>{{ comment.content }}</p> </div> </li> {% endfor %} </ul> <p>发表评论</p> <p> 昵称：<input type="text" id="tbCommentAuthor" class="author" disabled="disabled" size="50" value="{{ request.user.username }}"> </p> <p>评论内容:</p> <textarea name="" id="comment_content" cols="60" rows="10"></textarea> <p> <button class="btn btn-default common_btn">提交评论</button> </p> </div> <script> //点赞请求； $("#div_digg .action").click(function () { var is_up = $(this).hasClass("diggit"); // alert(is_up) //传Ajax事件； $obj = $(this).children("span"); $.ajax({ url: "/digg/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "is_up": is_up, "article_id": "{{ article_obj.pk }}", }, success: function (data) { console.log(data); if (data.state) { var val = parseInt($("#digg_count").text()); $obj.text(val + 1); } else { var val = data.handled ?

66-博客系统之render显示
1、通过render方法进行子评论的显示；
2、Bootstrap的well属性的引用；
{% if comment.parent_comment_id %} <div class="pid_info well"> <p> {{ comment.parent_comment.user.username }}:{{ comment.parent_comment.content }} </p> </div> {% endif %}
67-博客系统之Ajax显示子评论的思路
1、基于Ajax实现局部刷新功能；
var pid = ""; $(".common_btn").click(function () { var content = $("#comment_content").val(); if (pid) { var index = content.indexOf("\n"); content = content.slice(index + 1) } $.ajax({ url: "/comment/", type: "post", data: { "csrfmiddlewaretoken": $("[name = 'csrfmiddlewaretoken']").val(), "article_id": "{{ article_obj.pk }}", "content": content, pid: pid, }, success: function (data) { console.log(data); var create_time = data.create_time; var username = data.username; var content = data.content; var s = ` <li class="list-group-item"> <div> <span>${create_time}</span> <a href=""><span>${username}</span></a> </div> <div class="comment_con"> <p>${content}</p> </div> </li>`; $("ul.comment_list").append(s); //清空评论框; pid = ""; $("#comment_content").val("") } }) });
68-博客系统之评论树简介
1、递归展示数据的优缺点；
69-博客系统之评论树的请求数据
1、构建评论树的url以及视图函数；
path('get_comment_tree/', views.get_comment_tree),
def get_comment_tree(request): article_id = request.GET.get("article_id") ret = list(models.Comment.objects.filter(article_id=article_id).values("pk", "content", "parent_comment_id")) return JsonResponse(ret, safe=False)
70-博客系统之展开评论树
1、点击评论树展示根评论；

72-博客系统之评论树的思考1
基于主键的order_by设置；
def get_comment_tree(request): article_id = request.GET.get("article_id") ret = list(models.Comment.objects.filter(article_id=article_id).order_by("pk").values("pk", "content", "parent_comment_id")) return JsonResponse(ret, safe=False)
73-博客系统之评论树的思考2
1、评论树不再绑定click事件，直接通过Ajax进行展示；
<script> $.ajax({ url: "/get_comment_tree", type: "get", data: { article_id: "{{ article_obj.pk }}" }, success: function (comment_list) { console.log(comment_list); $.each(comment_list, function (index, comment_object) { var pk = comment_object.pk; var content = comment_object.content; var parent_comment_id = comment_object.parent_comment_id; var s = '<div class = "comment_item" comment_id=' + pk + '><span>' + content + '</span> </div>'; if (!parent_comment_id) { $(".comment_tree").append(s) } else { $("[comment_id=" + parent_comment_id + "]").append(s); } }) } }); </script>
74-博客系统之评论事务操作
1、Django中事物的引入，with transaction.atomic()方法的使用；
2、comment视图函数的写法；
def comment(request): print(request.POST) article_id = request.POST.get("article_id") pid = request.POST.get("pid") content = request.POST.get("content") user_id = request.user.pk #绑定事物操作； with transaction.atomic(): comment_obj = models.Comment.objects.create(user_id=user_id, article_id=article_id, content=content, parent_comment_id=pid) models.Article.objects.filter(pk=article_id).update(comment_count=F("comment_count") + 1) response = {} response["create_time"] = comment_obj.create_time.strftime("%Y-%m-%d %X") response["username"] = request.user.username response["content"] = content return JsonResponse(response)
75-博客系统之评论的邮件发送new
1、settings.py文件中配置邮箱信息；
EMAIL_HOST = 'smtp.exmail.qq.com' # 如果是 163 改成 smtp.163.com EMAIL_PORT = 465 EMAIL_HOST_USER = '290799238@qq.com' # 帐号 EMAIL_HOST_PASSWORD = 'hmefdscufpbnxafbjib' # 密码 DEFAULT_FROM_EMAIL = EMAIL_HOST_USER EMAIL_USE_SSL = True
2、comment视图函数；
def comment(request): print(request.POST) article_id = request.POST.get("article_id") pid = request.POST.get("pid") content = request.POST.get("content") user_id = request.user.pk article_obj = models.Article.objects.filter(pk=article_id).first() # 绑定事物操作； with transaction.atomic(): comment_obj = models.Comment.objects.create(user_id=user_id, article_id=article_id, content=content, parent_comment_id=pid) models.Article.objects.filter(pk=article_id).update(comment_count=F("comment_count") + 1) response = {} response["create_time"] = comment_obj.create_time.strftime("%Y-%m-%d %X") response["username"] = request.user.username response["content"] = content # 发送邮件； from django.core.mail import send_mail from cnblogs import settings send_mail( "您的文章%s新增了一条内容" % article_obj.title, content, settings.EMAIL_HOST_USER, ["tqtl@tqtl.org"] ) # import threading # t = threading.Thread(target=send_mail,args = ( # "您的文章%s新增了一条内容" % article_obj.title, # content, # settings.EMAIL_HOST_USER, # ["tqtl@tqtl.org"] # # )) # t.start() return JsonResponse(response)
