configuring django-celery for database backend
===

I'm working through the "First Steps with Celery" tutorial, and while I will move to a non-database solution later, I don't want to get into that now.  I just want to use the database backend that comes with djcelery.

So what should the value of the 'backend' parameter be in the following code:

    from celery import Celery
    celery = Celery('tasks', broker='django://',backend='XXXX')

I've tried:

"database" (which fails because SQLAlchemy is not installed)

"djcelery" (module object is not callable)

"djcelery.backends" (module object has no attribute "backends")
