14051	Signals for transaction commit/rollback	Ask Solem <ask@…>	nobody	"Some users of django-celery have the problem of publishing references to database state that has not yet been commited.

E.g:

{{{
    def add_user(request):
        user = User.objects.create(...)
        # Import the users address book contacts asynchronously using the worker pool.
       import_contacts.delay(user.pk)
}}}

The proposed solution is to add a way to delay these calls until the transaction is committed:

{{{
    from djcelery import on_transaction_commit

    def add_user(request):
        user = User.objects.create(...)
        on_transaction_commit(import_contacts.delay, user.pk)
}}}

I can't see any mechanism to hook into commit/rollback, so it doesn't seem easy
to accomplish.

Do you think it could be possible to add new signals for transaction commit/rollback?"
