BaseDeleteView引发AttributeError(render_to_response丢失) [英] BaseDeleteView throws AttributeError (render_to_response missing)

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.我想要实现的是将 GET 请求发送到激活URI(注册后每封电子邮件发送).在此视图中，我首先将HTTP请求发送到后端，然后从前端数据库中删除激活对象.我不想有一个确认页面，所以 DeleteView 是不可能的.

I try to implement a view based on BaseDeleteView for a website that acts as a frontend to an REST backend. Both sides communicate over HTTP requests. What I want to achieve is that I send a GET request to an activation URI (send per email after registration). Inside this view I first send a HTTP request to a backend, and then delete the activation object from the database of the frontend. I don't want to have a confirmation page, so DeleteView is not possible.

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"),

但是出现以下错误:

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

在我看来，它甚至都不应该调用render_to_response.有什么想法吗?

In my eyes it shouldn't even call render_to_response. Any ideas?

推荐答案

如果要忽略确认页面，只需直接通过POST调用DeleteView.这是最理想的，因为删除对象应受csrf保护.

If you want to leave out the confirmation page, just call your DeleteView directly with POST. This is most desirable as the deletion of an object should be protected by csrf.
