Django学习(实现登录功能)
1.登录功能
1).在test项目中，修改配置文件setting.py 此时连接mysql数据库
DATABASES = { 'default': { # 'ENGINE': 'django.db.backends.sqlite3', #'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), 'ENGINE': 'django.db.backends.mysql', 'NAME': 'pro202', 'HOST': '127.0.0.1', 'PORT': 3306, 'USER': 'root', 'PASSWORD': '123456' } }
2).数据的模型类
# -*- coding: utf-8 -*- from __future__ import unicode_literals from django.db import models # Create your models here. class Student(models.Model): sname = models.CharField(max_length=30) spwd = models.CharField(max_length=30) def __unicode__(self): return r'Student:%s%s'%(self.sname,self.spwd)
3).生成数据库表
#创建当前应用的迁移文件 python manage.py makemigrations stu #生成数据库表 python manage.py migrate
4).配置url
#test\urls
from django.conf.urls import url, include from django.contrib import admin import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^student/',include('stu.urls')) ]
#stu\urls
#coding=utf-8 from django.conf.urls import url import views urlpatterns=[ url(r'^login/$',views.login) ]
5).配置视图函数
# -*- coding: utf-8 -*- from __future__ import unicode_literals from django.http import HttpResponse from django.shortcuts import render def login(request): if request.method == 'GET': return render(request,'login.html') else: uname = request.POST.get("uname","") pwd = request.POST.get("pwd","") if uname and pwd: c = Student.objects.filter(sname=uname,spwd=pwd).count() if c == 1: return HttpResponse('登录成功') return HttpResponse('登录失败')
6).处理登录功能
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form action="/student/login/" method="post"> {% csrf_token %} <p> <label>用户名：<input type="text" name="uname"></label> </p> <p> <label >密 码：<input type="password" name="pwd"></label> </p> <p> <lable><input type="submit" value="登录"></lable> </p> </form> </body> </html>
7).访问127.0.0.1:8000/student/login/
