Signals for transaction commit/rollback

[Ask Solem <ask@…>]

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
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)

This doesn't seem very easy to accomplish, as I can't see any mechanism
to hook into commit/rollback. Do you think it could be possible
to add new signals for this?

Formatting is broken, resubmitting :(
