CreateView + 重新定义 form_valid = 没有 return HttpResponse 对象

Question

Django 1.10强文本

你能帮我理解为什么会导致：

视图 wiki.views.WikiCreate 没有 return HttpResponse 对象。它 return 改为 None。

post: 我在重新定义 post 方法时没有干扰继承链。我刚刚截取了url.

的参数

form_valid: 我 return 编辑了 HttpResponse。但似乎后来在某个地方消失了。

urlpatterns = [
    url(r'^(?P<model>[-\w]+)/(?P<pk>\d+)/wiki/create/$', WikiCreate.as_view(), name='wiki_create'),
]



class WikiCreate(CreateView):
    model = Wiki
    fields = ['article']

    def post(self, request, *args, **kwargs):
        #For wiki history.
        self.author = request.user

        # Parameters from url reflect fields not shown to user.
        self.related_model = kwargs.get('model')
        self.related_object_id = kwargs.get('pk')

        super(WikiCreate, self).post(request, *args, **kwargs)

    def form_valid(self, form):
        """
        Only "article" field was shown to tue user.
        Now we save fields that were not explicitly shown (but were in the url).
        """
        self.object = form.save(commit=False)
        self.object.related_model = self.related_model
        self.object.related_id = self.related_object_id
        self.object.save()
        return HttpResponseRedirect(self.get_success_url())

您没有 return 来自 post 中超级调用的响应。

请注意，覆盖该方法很少是个好主意，您当然不需要在这里。您可以直接在 form_valid.

中访问这些 kwargs

CreateView + 重新定义 form_valid = 没有 return HttpResponse 对象

CreateView + redefinition of form_valid = didn't return an HttpResponse object
