python - 如何使用django登录

Question

我有以下代码，但收到一条错误消息:“用户对象没有属性 POST”

def login (request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(user)
            return render(request, 'base_in/base_in.html', {})
        else:
            return render(request, 'signupapp/error.html', {'message':'the acount is not active'})
    else:
        return render(request, 'signupapp/error.html', {'message':'username and password is incorrect'})

我也尝试了这段代码并得到了另一个错误:“login() takes 1 positional argument but 2 were given”

def login (request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(user)
            return render(request, 'base_in/base_in.html', {})
        else:
            return render(request, 'signupapp/error.html', {'message':'the acount is not active'})
    else:
        return render(request, 'signupapp/error.html', {'message':'username and password is incorrect'})

我做错了什么？基于 django 教程，它应该可以正常工作:

https://docs.djangoproject.com/en/1.9/topics/auth/default/#how-to-log-a-user-in

发生的事情是您尝试从 django.contrib.auth 调用 的 login，但您还定义了自己的函数 login()，你这里有一种名称冲突。

您应该将其重命名为其他名称，例如login_view()

from django.contrib.auth import authenticate, login

def login_view(request): # If you call it login,
                         # you get conflict with login imported aove
     # The rest of your code here
     # now if you call login(user), it will use the correct one,
     # i.e. the one imported from django.contrib.auth

如果你不想重命名，你可以用不同的名字导入 Django 的 login，例如

from django.contrib.auth import login as auth_login

# Then use auth_login(user) in your code
