第十九 django继续及CRM
1.创建新项目
2.设计数据库表
from django.db import models # Create your models here. from django.contrib.auth.models import User course_type_choices = (('online', '网络班'), ('offline_weekend', '面授班（周末'), ('offline_fulltime', '面授班（脱产）'), ) class School(models.Model): name = models.CharField(max_length=128,unique=True) city = models.CharField(max_length=64) addr = models.CharField(max_length=128) def __unicode__(self): return self.name class UserProfile(models.Model): User = models.OneToOneField(User) name = models.CharField(max_length=64) school = models.ForeignKey('School') def __unicode__(self): return self.name class Customer(models.Model): qq = models.CharField(max_length=64,unique=True) name = models.CharField(max_length=32,blank=True,null=True) phone = models.BigIntegerField(blank=True,null=True) course = models.ForeignKey('Course') course_type = models.CharField(max_length=64,choices=course_type_choices,default='offline_weekend') consult_memo = models.TextField() source_type_choices = (('qq','qq群'), ('referral','内部转介绍'), ('agent',''), ('others','其它'), ) source_type = models.CharField(max_length=64,choices=source_type_choices,default='qq') referral_from = models.ForeignKey('self',blank=True,null=True) status_choices = (('signed','已报名'), ('unregistered','未报名'), ('graduated','已毕业'), ('drop-off','退学'), ) status = models.CharField(max_length=64,choices=status_choices,default='signed') consultant = models.ForeignKey('UserProfile') class_list = models.ManyToManyField('ClassList',blank=True) date = models.DateField('咨询日期',auto_now_add=True) def __unicode__(self): return "%s (%s)" %(self.qq,self.name) class CustomerTrackRecord(models.Model): customer = models.ForeignKey(Customer) track_record = models.TextField('跟踪记录') track_date = models.DateField() follower = models.ForeignKey(UserProfile) status_choices = ((1,'近期无报名计划'), (2,'2个月内报名计划'), (3,'1个月内报名计划'), (4,'2周内报名计划'), (5,'1周内报名计划'), (6,'2天内报名'), (7,'已报名'), ) status = models.IntegerField('状态',choices=status_choices,help_text='选择此客户的原因') def __unicode__(self): return self.customer class Course(models.Model): name = models.CharField(max_length=64,unique=True) online_price = models.IntegerField() offline_price = models.IntegerField() introduction = models.TextField() def __unicode__(self): return self.name class ClassList(models.Model): course = models.ForeignKey(Course,verbose_name='课程') semester = models.IntegerField(verbose_name='学期') course_type = models.CharField(max_length=64, choices=course_type_choices, default='offline_weekend') teachers = models.ManyToManyField(UserProfile) start_date = models.DateField() graduate_date = models.DateField() def __unicode__(self): return "%s(%s) %s" %(self.course.name,self.course_type,self.semester) class Meta: unique_together = ('course','semester','course_type') class CourseRecord(models.Model): class_obj = models.ForeignKey(ClassList) day_num = models.IntegerField("第几节课") course_date = models.DateField(auto_now_add=True,verbose_name='上课时间') teacher = models.ForeignKey(UserProfile) def __unicode__(self): return self.class_obj,self.day_num class Meta: unique_together = ('class_obj','day_num') class StudyRecord(models.Model): course_record = models.ForeignKey(CourseRecord) student = models.ForeignKey(Customer) record_choices = (('checked','已签到'), ('late','迟到'), ('noshow','缺勤'), ('leave_early','早退') ) record = models.CharField("状态",choices=record_choices,max_length=64) score_choices = ((100,'A+'), (90,'A'), (80,'A-'), (70,'B+'), (60,'B'), (50,'C'), (40,'C-'), (0,'D'), (-1,'N/A'), (-100,'COPY'), (-1000,'FAIL') ) score = models.IntegerField("本节成绩",choices=score_choices,default=-1) date = models.DateTimeField(auto_now_add=True) note = models.CharField('备注',max_length=255,blank=True,null=True) def __unicode__(self): return "%s %s %s" %(self.course_record,self.student,self.record)

查看结果：
11.分页
11.1.django分页模块
https://docs.djangoproject.com/en/2.0/topics/pagination/
11.2.新增数据
11.3.配置分页
11.3.1.配置后端返回
from django.shortcuts import render from cklcrm import models # Create your views here. from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger def dashboard(request): return render(request,'cklcrm/dashboard.html') def customers(request): customers_list = models.Customer.objects.all()
#返回每页显示的条数 paginator = Paginator(customers_list,3) page = request.GET.get('page') try: customer_pages = paginator.page(page) except PageNotAnInteger:
#如果输入的页数不存在，默认返回第一页 customer_pages = paginator.page(1) except EmptyPage:
#如果页数超出，则返回最后一页 customer_pages = paginator.page(paginator.num_pages) # return render(request,'cklcrm/customers.html',{'customers_list':customers_list}) return render(request, 'cklcrm/customers.html', {'customers_list': customer_pages})
11.3.2.配置前端返回
在表格下面新增如下：
<div class="pagination"> <span class="step-links"> {% if customers_list.has_previous %} <a href="?page=1">« first</a> <a href="?page={{ customers_list.previous_page_number }}">previous</a> {% endif %} <span class="current"> Page {{ customers_list.number }} of {{ customers_list.paginator.num_pages }}. </span> {% if customers_list.has_next %} <a href="?page={{ customers_list.next_page_number }}">next</a> <a href="?page={{ customers_list.paginator.num_pages }}">last »</a> {% endif %} </span> </div>
11.3.查看页面
11.4.分页优化一
11.4.1.增加如下样式
https://v3.bootcss.com/components/#pagination
11.4.2.前端展示增加
<nav aria-label=""> <ul class="pagination"> <!-- 如果还有上一页，则增加想做的箭头 --> {% if customers_list.has_previous %} <li class=""><a href="?page={{ customers_list.previous_page_number }}" aria-label="Previous"><span aria-hidden="true">«</span></a></li> {% endif %} <!-- 循环页码，展示所有页码 --> {% for page_num in customers_list.paginator.page_range %} <!-- 如果循环页码等于当前页码，则增加样式 --> {% if page_num == customers_list.number %} <li class="active"><a href="?page={{ page_num }}">{{ page_num }} <span class="sr-only">(current)</span></a></li> {% else %} <li class=""><a href="?page={{ page_num }}">{{ page_num }} <span class="sr-only">(current)</span></a></li> {% endif %} {% endfor %} <!-- 如果还有下一页，则增加向右的箭头 --> {% if customers_list.has_next %} <li class=""><a href="?page={{ customers_list.next_page_number }}" aria-label="Next"><span aria-hidden="true">»</span></a></li> {% endif %} </ul> </nav>
11.4.3.查看结果
11.5.增加页码缩减
11.5.1.如果页码很多，就没办法全部显示
11.5.2.优化办法，只显示当前页的最近两三页
思路：获取当前页码号码，然后取当前页 减去 循环的页数，如果小于等于2则正确
abs(current_page - i_page )
比如当前是10
abs(10 - 8)
abs(10 - 12)
但是，没有这个方法，所以需要自定义
11.5.3.自定义返回前端页码方法
https://docs.djangoproject.com/en/2.0/howto/custom-template-tags/
11.5.4.方法演示
11.5.4.1.新增包
#!/usr/bin/env python # -*- coding: utf-8 -*- from django import template register = template.Library() @register.filter def ckl_upper(val): print("-- from my temp:") return val.upper()
11.5.4.2.前端返回引用
前端引用自定义方法

12.选择查看详细信息
12.1.点击id进入详细信息
12.1.1.添加a标签，点击a标签进入详细页
思路：当前页面是：http://127.0.0.1:8000/cklcrm/customers/?page=1
希望点击id，进入：http://127.0.0.1:8000/cklcrm/customers/1/ 此处是详细信息
12.1.2.增加url
from django.conf.urls import url,include from django.contrib import admin from cklcrm import views urlpatterns = [ url(r'^$',views.dashboard), url(r'^customers/$',views.customers), url(r'^customers/(\d+)/$',views.customsers_detail) ]
12.1.3.使用modelfrom
新增forms
#!/usr/bin/env python # -*- coding: utf-8 -*- from django.forms import Form,ModelForm from cklcrm import models class CustomerModelForm(ModelForm): class Meta: model = models.Customer exclude = ()
12.1.4.配置views方法
from django.shortcuts import render from cklcrm import models
#导入forms from cklcrm import forms # Create your views here. from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger def dashboard(request): return render(request,'cklcrm/dashboard.html') def customers(request): customers_list = models.Customer.objects.all() paginator = Paginator(customers_list,3) page = request.GET.get('page') try: customer_pages = paginator.page(page) except PageNotAnInteger: customer_pages = paginator.page(1) except EmptyPage: customer_pages = paginator.page(paginator.num_pages) # return render(request,'cklcrm/customers.html',{'customers_list':customers_list}) return render(request, 'cklcrm/customers.html', {'customers_list': customer_pages})
#返回forms结果 def customsers_detail(request,customer_id): customer_obj = models.Customer.objects.get(id=customer_id) form = forms.CustomerModelForm() return render(request,'cklcrm/customers_detail.html',{'customer_form':form})
12.1.5.添加静态文件

再次查看：
12.1.8.给某个字段加样式
比如让qq这个字段
修改forms
#!/usr/bin/env python # -*- coding: utf-8 -*- from django.forms import Form,ModelForm from cklcrm import models class CustomerModelForm(ModelForm): class Meta: model = models.Customer exclude = () def __init__(self,*args,**kwargs): super(CustomerModelForm,self).__init__(*args,**kwargs) self.fields['qq'].widget.attrs["class"] = "form-control"

13.权限管理
13.1.增加表字段
表字段，临时随机找的表增加

13.2.运行添加
13.3.先说URL别名
13.3.1.django的url别名很灵活
如果要访问：http://127.0.0.1:8000/cklcrm/customers/2/
后面的 2 如果写死就不好了，无法匹配到后面的3，4 ..等
from django.conf.urls import url,include from django.contrib import admin from cklcrm import views urlpatterns = [ url(r'^$',views.dashboard), url(r'^customers/$',views.customers), url(r'^customers/(\d+)/$',views.customsers_detail,name="customer_detail"), #此处使用了别名 ]
13.3.2.返回页面修改访问url
原：
<td><a href="/cklcrm/customers/{ customer.id }}">{ customer.id }}</a></td>
现：
<td><a href="{% url 'customer_detail' customer.id %}">{{ customer.id }}</a></td>
url 是调用路径
'customer_detail' 是调用的url别名
customer.id 是url的id
13.3.3.查看元素
13.4.继续接 13.2.
增加url别名
from django.conf.urls import url,include from django.contrib import admin from cklcrm import views urlpatterns = [ url(r'^$',views.dashboard), url(r'^customers/$',views.customers,name="customer_list"), url(r'^customers/(\d+)/$',views.customsers_detail,name="customer_detail"), ]
