有没有办法列出Django信号？ [英] Is there a way to list Django signals?

问题描述

有没有办法查看在Django中设置了哪些信号？

Is there a way to see which signals have been set in Django?

推荐答案

它并没有在文档中公开，但是Signal只是一个包含在事件上调用的接收者列表的类。您可以手动检查以下列表：

It's not really exposed in docs but Signal is just a class that contains a list of receivers which are called on event. You can manually check this list:

from django.db.models.signals import *

for signal in [pre_save, pre_init, pre_delete, post_save, post_delete, post_init, post_syncdb]:
    # print a List of connected listeners
    print signal.receivers
