BaseDeleteView throws AttributeError (render_to_response missing)

I try to implement a view based on开发者_运维知识库 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())

My urls.py looks like that:

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

But I get the following error:

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

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

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.

You've inherited from BaseDeleteView, which as the documentation states, doesn't include the TemplateResponseMixin - ie all the bits that are to do with rendering a response.

Inherit from DeleteView instead.
