CreateView的+ form_valid =的重新定義沒有返回HttpResponse對象

Question

Django的1.10 強大的文本

你能幫我明白爲什麼這會導致：

視圖wiki.views.WikiCreate沒」返回一個HttpResponse對象。它返回None而不是。

post：重新定義post方法時，我並沒有干涉繼承鏈。我剛剛截獲了來自url的參數。

form_valid：我返回了HttpResponse。但似乎在某個地方後來消失了。

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())

您沒有從post中的超級呼叫中返回響應。

請注意，重寫該方法並不是一個好主意，並且您當然不需要在這裏。您可以直接通過form_valid訪問這些kwargs。
