python - View app.views.MyWizard 未返回 HttpResponse 对象

Question

这是我的观点.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/")

为什么会出现此错误以及如何修复它？

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

如果用户未经过身份验证，您的 dispatch() 方法不会返回 HttpResponse 对象:

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)

希望有帮助。
