Question

我尝试为一个充当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。我想要实现的是我向激活URI发送GET请求（注册后发送每封电子邮件）。在此视图中，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。我不想要一个确认页面，因此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"),

但是我收到以下错误：

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？

Answer 1

如果您想省略确认页面，只需使用POST直接调用DeleteView即可。这是最理想的，因为对象的删除应该受到csrf的保护。

Answer 2

您继承自BaseDeleteView，其中the documentation个状态不包含TemplateResponseMixin - 即与呈现响应有关的所有位。

继承DeleteView。

BaseDeleteView抛出AttributeError（缺少render_to_response）
