Django登錄表單不適用於自定義用戶模型

Question

我正在使用Django 1.8，並實現了自定義用戶模型。 用戶注冊件具有100％的功能； 我可以提交表單並驗證是否創建了用戶。 但是我在用戶登錄過程中苦苦掙扎。

登錄表單可以很好地顯示，但是當我輸入已驗證（通過Django管理員驗證）的用戶名和密碼時，我會收到HttpResponse（'Form is invalid'）消息。

我已經堅持了這一天一兩天。 任何建議，不勝感激！

Answer 1

該錯誤意味着您在“ CustomUserLoginView”中的“ post”方法未返回HttpResponse，因為您只有很少的“ pass”而不是返回正確的響應。 這是因為在少數情況下您什么也不做，然后到達方法的底部，並且默認情況下python函數/方法返回None。 在一種情況下（當user.is_active時），您僅返回HttpResponse。 您應該看到您要傳遞“ if-else”的哪個分支。 在所有情況下（總是），您都必須返回HttpResponse。

玩得開心！

Answer 2

這個答案最終使我得以解決。

在“發布”方法中，我需要將行更改為：

form = self.form_class(request.POST)

至：

form = self.form_class(data=request.POST)

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
