BaseDeleteView 抛出 AttributeError（render_to_response 缺失）答案

【问题描述】：

我尝试为充当 REST 后端前端的网站实现基于 BaseDeleteView 的视图。双方通过 HTTP 请求进行通信。我想要实现的是向激活 URI 发送 GET 请求（注册后通过电子邮件发送）。在这个视图中，我首先向后端发送 HTTP 请求，然后从前端的数据库中删除激活对象。我不想有确认页面，所以DeleteView 是不可能的。

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())

我的urls.py 看起来像这样：

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

但我收到以下错误：

Traceback (most recent call last):

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

在我看来，它甚至不应该调用 render_to_response。有什么想法吗？

【解决方案1】：

如果您想省略确认页面，只需使用 POST 直接调用您的 DeleteView。这是最可取的，因为对象的删除应该受到 csrf 的保护。

【解决方案2】：

您从BaseDeleteView 继承，正如the documentation 所述，不包括TemplateResponseMixin - 即与呈现响应有关的所有位。

改为从DeleteView 继承。

【讨论】：

但如果我从DeleteView 继承，我必须在单独的页面中确认删除。我真的不想要这个。我想要的是向 URI 发送 GET 请求并执行删除。然后我重定向到不同的 URI。
