BaseDeleteView抛出AttributeError（render_to_response missing）

我尝试基于BaseDeleteView实现一个视图，该视图充当前端到REST后端的网站。双方通过HTTP请求进行通信。我想实现的是，我发送一个GET请求到激活URI（注册后通过每封电子邮件发送）。在这个视图中，我首先发送一个HTTP请求到后端，然后从前端的数据库中删除激活对象。我不想要确认页面，所以​​是不可能的。BaseDeleteView抛出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看起来像这样：

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

，但我得到了以下错误：

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

在我眼里它不应该叫连选择render_to_response。有任何想法吗？

回答：

您从BaseDeleteView继承而来，其中the documentation指出，不包括TemplateResponseMixin - 即所有与呈现响应有关的位。

改为从​​继承。

回答：

如果你想省略确认页面，只需用POST直接调用你的DeleteView即可。这是最理想的，因为删除对象应该由csrf保护。
