Best approach to execute tasks inside django admin views

[Marc Aymerich]

Hi guys,
I have an application that execute some tasks after an object is
modifyed through django admin interface. In order to do that I'm
subscribed to django.contrib.admin.models.EntryLog post_save signal
and for each signal I execute a celery task.

As you migh know django admin views are running under
commit_on_success transaction so executing tasks within can lead to
some issues, good explained on the celery documentation:
http://ask.github.com/celery/userguide/tasks.html#database-transactions

So my question is, how do I should deal with this transactions?
it is possible to manually commit a commit_on_success transaction
before calling the task?
if not, what would you do? monkeypatch django admin views to use
commit_manually?
subclass all your project modelAdmin classes? (I'm using a lot of
reusable applications)

thank you guys!
