Django CreateView的信号？

Question

我一直在使用CreateView的几种模式：

class JsonResponseMixin(object): 

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

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

我的问题是我怎么能在Django CreateView的发送信号像car_create.send()？

Answer 1

我创建了一个自定义CreateView与form_valid发送该信号。
