視圖app.views.MyWizard沒有返回HttpResponse對象

Question

這是我的views.py：

class OnlyNonLoggedInMixin(object):
    def dispatch(self, request, *args, **kwargs):
        if request.user.is_authenticated():
            return HttpResponseRedirect("/page/")

class MyWizard(OnlyNonLoggedInMixin, SessionWizardView):
    def get_template_names(self):
        return [TEMPLATES[self.steps.current]]

    def done(self, form_list, **kwargs):
        form_data = process_form_data(form_list)
        return HttpResponseRedirect("/ok/")

為什么我有此錯誤，以及如何解決？

The view app.views.MyWizard didn't return an HttpResponse object.

萬一用戶未通過身份驗證，您的dispatch()方法不會返回HttpResponse對象：

class OnlyNonLoggedInMixin(object):
    def dispatch(self, request, *args, **kwargs):
        if request.user.is_authenticated():
            return HttpResponseRedirect("/page/")
        return super(OnlyNonLoggedInMixin, self).dispatch(
            self, request, *args, **kwargs)

希望能有所幫助。
