Description

Calling instance.save() inside a post_save signal receiver causes a loop and max recursion error. This problem is very easy to fall into and the best solution at the moment is call the QuerySet update() method, so that the post_save signal is not called in this case.

This is a very ugly workaround. I think Django should give the option to call save() and explicitly suppress signal emmiting. For example:

instance.save(post_save=False)

In the above method call, post_save signal would not be sent, and the loop problem would not occurs.
