BaseDeleteView拋出AttributeError（render_to_response missing）

我嘗試基於BaseDeleteView實現一個視圖，該視圖充當前端到REST後端的網站。雙方通過HTTP請求進行通信。我想實現的是，我發送一個GET請求到激活URI（註冊後通過每封電子郵件發送）。在這個視圖中，我首先發送一個HTTP請求到後端，然後從前端的數據庫中刪除激活對象。我不想要確認頁面，所以是不可能的。BaseDeleteView拋出AttributeError（render_to_response missing）

class ActivationView(BaseDeleteView): 
    success_url = "/activation/success/" 

    def get_object(self, queryset=None): 
     uuid = self.kwargs['uuid'] 
     try: 
      obj = AccountRegistration.objects.get(uuid=uuid) 
     except ObjectDoesNotExist: 
      raise Http404('Registration not found.') 

     return obj 

    def delete(self, request, *args, **kwargs): 
     obj = self.get_obj() 

     if obj.expire_date < datetime.now(): 
      obj.delete() 
      raise Http404('Registration expired.') 

     # send a http request to the backend 
     t = Transaction('/activate/%s/' % obj.account_name) 
     t.emit() 

     # delete the object 
     obj.delete() 

     # and redirect the request 
     return HttpResponseRedirect(self.get_success_url())

我urls.py看起來像這樣：

url(r'^activate/(?P<uuid>\w+)/$', 
    ActivationView.as_view(), name="account-activate"),

，但我得到了以下錯誤：

AttributeError: 'ActivationView' object has no attribute 'render_to_response'

在我眼裏它不應該叫連選擇render_to_response。有任何想法嗎？
