排序Django信号的接收器 [英] Sort django signal's receivers

问题描述

Django以自己的方式调用接收器方法.有什么办法可以对Django信号的接收者进行排序?在官方的Django文档中没有找到任何与此相关的信息.

Django calls receiver methods in its own way. Is there any way that we can sort the receivers of Django signal? I didn't find anything related to it in official Django documentation.

推荐答案

所有信号的接收器功能都按照它们被注册的顺序一次被调用."

"All of the signal’s receiver functions are called one at a time, in the order they were registered."

尝试:

@receiver(signals.pre_save, sender=User)
def signal_receiver_1(*args, **kwargs):
    print('RECEIVER 1')

@receiver(signals.pre_save, sender=User)
def signal_receiver_2(*args, **kwargs):
    print('RECEIVER 2')

@receiver(signals.pre_save, sender=User)
def signal_receiver_3(*args, **kwargs):
    print('RECEIVER 3')

输出将是:

RECEIVER 1
RECEIVER 2
RECEIVER 3

然后将其混合...
