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