Trigering post_save signal only after transaction has completed

Question

I have written some APIs, for which the respective functions executive inside a transaction block. I am calling the save() method (after some modifications) on

Answer 1

I was having serious issues with django's admin not allowing post_save transactions on parent objects when they had inline children being modified.

This was my solution to an error complaining about conducting queries in the middle of an atomic block:

def on_user_post_save_impl(user):
     do_something_to_the_user(user)

def on_user_post_save(sender, instance, **kwargs):
    if not transaction.get_connection().in_atomic_block:
        on_user_post_save_impl(instance)
    else:
        transaction.on_commit(lambda: on_user_post_save_impl(instance))
