如何使用Django登录 [英] how to use django login

问题描述

我有以下代码，但出现错误消息:用户对象没有属性POST"

I have the following code and I get an error saying: "the User object has no attribute 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，并遇到另一个错误:"login()接受1个位置参数，但给出了2个位置"

I also tried this code and got another error: "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?根据django教程，它应该可以正常工作:

What am I doing wrong? Based on django tutorials it should work properly:

推荐答案

发生了什么事，您尝试从django.contrib.auth 调用的 login .还定义了自己的名为 login()的函数，您在这里会遇到一种名称冲突.

What happened is you try to call login of from django.contrib.auth, but you are also defining your own function called login(), you have a kind of name conflict here.

您应该将其重命名为其他名称，例如 login_view()

You should rename that to something else, e.g. 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

如果您不想重命名，则可以使用其他名称(例如

If you prefer not to rename, you can import Django's login under a different name, e.g.

from django.contrib.auth import login as auth_login

# Then use auth_login(user) in your code
