您在这里有一个错字，您覆盖了 form_valid ，但是您写了 post_valid 。

You have a typo there, you are overriding form_valid but you have written post_valid.

def form_valid(self, form):
    review = form.save(Commit=False)
    review.lawyer = get_object_or_404(Lawyer, 
                                        slug=self.kwargs.get('slug'))
    review.reviewer = User.objects.get(user=self.request.user)

    # save and return HttpResponse
    review.save()
    return HttpResponseRedirect(self.get_success_url())

但是， super 调用仍将调用父类的 form_valid 仍然会引发错误。我认为您可以将评论保存在此重写的方法中，并返回基类返回的内容，即 return HttpResponseRedirect（self.get_success_url（））

But, the super call will still call the parent class' form_valid which will still raise the error. I think you can save the review in this overriden method and return what the base class returns i.e. return HttpResponseRedirect(self.get_success_url())
