带信号的Django CreateView？

Question

我有几个使用CreateView的模型：

class JsonResponseMixin(object):

    def is_valid(self, form):
        ...
        return HttpResponse(json.dumps(data))
    ...

class CarCreate(JsonResponseMixin, CreateView):
    model = Car
    form = CarForm
    success_url = '/success'

我的问题是如何在Django CreateView中发送car_create.send()信号？

Answer 1

我创建了一个自定义CreateView，form_valid发送了该信号。
