Python Django登录表单不适用于自定义用户模型

我正在使用Django 1.8，并实现了一个自定义用户模型。用户注册件100%可用；我可以提交表单并验证是否创建了用户。但是我在用户登录过程中遇到了困难

登录表单呈现得很好，但是当我输入一个用户名和密码，并且我已经验证了该用户名和密码是否已注册（通过Django admin验证）时，我会看到HttpResponse（“表单无效”）消息

我已经在这上面呆了一两天了。非常感谢您的任何建议

该错误意味着“CustomUserLoginView”中的“post”方法没有返回HttpResponse，因为您只有很少的“pass”而不是返回正确的响应。这是因为在少数情况下您什么都不做，然后到达方法的底部，默认情况下python函数/方法返回None。您只在一种情况下返回HttpResponse（当user.u处于活动状态时）。您应该查看“if-else”的哪个分支。在所有情况下都必须返回HttpResponse（始终）

玩得开心

最终让我找到了解决办法

在“post”方法中，我需要将行更改为：

form = self.form_class(request.POST)

致：

最后，我的CustomUserLoginView如下所示：

class CustomUserLoginView(FormView):
    form_class = AuthenticationForm
    template_name = 'registration/login.html'
    success_url = '/connections/'

    def get(self, request, *args, **kwargs):
        form = self.form_class(initial=self.initial)
        return render(request, self.template_name, {'form':form})

    def post(self, request, *args, **kwargs):
        form = self.form_class(data=request.POST)
        if form.is_valid():
            user = authenticate(
                username=form.cleaned_data['username'],
                password=form.cleaned_data['password'],
                )
            if user is not None:
                if user.is_active:
                    login(request, user)
                    return HttpResponseRedirect(self.success_url)
                else:
                    return HttpResponse('User is not active') # TEMP
            else:
                return HttpResponse('User does not exist') # TEMP
        else:
            return HttpResponse('Form is not valid') # TEMP

嗨，马丁，谢谢你的回答。我已经更新了代码，将HttpResponse对象包含在for every'else'语句中。我还将authenticate值从username=form['username']更改为form['email']。我正在提交一个电子邮件地址和一个密码，我100%确定它们是有效的（它们在Django管理员登录中工作），但我看到“用户不存在”。知道我做错了什么吗？嘿，乔，欢迎你。完美的我不知道，我唯一想改变的是你如何从表格中获得价值。您应该使用“form.cleaned_data['email']”和“form.cleaned_data['password']”。试试看，让我知道：）。谢谢
