有一种更简单的绑定
post_save信号的方法
from django.db.models.signals import post_savefrom myapp.models import Cardef do_something(sender, **kwargs): print 'the object is now saved.' car = kwargs['instance'] #now i have access to the objectpost_save.connect(do_something, sender=Car)
每次* 发出HTTP请求时，requestfinished
都会调用该信号，这是一次尝试。 *
