title: configuring django-celery for database backend
body: <p>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.</p>
  
  <p>So what should the value of the 'backend' parameter be in the following code:</p>
  
  <pre><code>from celery import Celery
  celery = Celery('tasks', broker='django://',backend='XXXX')
  </code></pre>
  
  <p>I've tried:</p>
  
  <p>"database" (which fails because SQLAlchemy is not installed)</p>
  
  <p>"djcelery" (module object is not callable)</p>
  
  <p>"djcelery.backends" (module object has no attribute "backends")</p>
