Django之auth模块

http://www.cnblogs.com/liwenzhou/p/9030211.html

1、首先导入auth模块

 from django.contrib import auth

2、创建auth表

　　manage.py makemigrations

　　manage.py migrate

　　这样才能使用

一、主要部分

 from django.shortcuts import render,redirect
 from django.contrib import auth
 # Create your views here.
 
 def index(request):
     if request.user.is_authenticated:
         username = request.user.username
         return render(request,"index.html",locals())
     return redirect("/login")
 
 def login(request):
     if request.method=="POST":
         username=request.POST.get("username")
         password=request.POST.get("password")
         user = auth.authenticate(username=username,password=password)
         auth.login(request,user)
         if user:
             return redirect("/index")
         else:
             return render(request,"login.html")
     return render(request,"login.html",locals())
 
 def logout(request):
     auth.logout(request)
     return redirect("/login")

二、auth对象

　　1、创建用户

 from django.contrib.auth.models import
 User.objects.create_superuser(.......)      #创建超级用户
 Use.objects.create_user(....)      #创建普通用户

　　2、修改密码

 def set_pwd(request):
     if request.method == "POST":
         old_pwd = request.POST.get("old_pwd")
         new_pwd = request.POST.get("new_pwd")
         if request.user.check_password(raw_password=old_pwd):
             request.user.set_password(new_pwd)
             request.user.save()
             return redirect("/index")
     return render(request,"set_pwd.html",locals())

三、扩展auth表

 from django.contrib.auth.models import AbstractUser
 class UserInfo(AbstractUser):
     """
     用户信息表
     """
     nid = models.AutoField(primary_key=True)
     phone = models.CharField(max_length=11, null=True, unique=True)
 
     def __str__(self):
         return self.username

使用继承的方式扩展auth表，需要在settings中配置默认的路径：

 # 引用Django自带的User表，继承使用时需要设置
 AUTH_USER_MODEL = "app名.UserInfo"
