How can I prevent post_save recursion in Django?

Question

I have some problems when using signal in Django.

post_save occurs recursion because of instance.save() inside of function.

Answer 1

Disconnect the signal before save, then connect again. https://docs.djangoproject.com/en/1.10/topics/signals/#disconnecting-signals

def post_save_product(sender, instance, **kwargs):
    post_save.disconnect(post_save_product, sender=sender)
    instance.do_stuff()
    instance.save()
    post_save.connect(post_save_product, sender=sender)
post_save.connect(post_save_product, sender= Product)
