title: Django with celery can't get result from backend
body: <p>My django project is cloned from Celery repo: <a href="https://github.com/celery/celery/tree/3.1/examples/django" rel="nofollow">https://github.com/celery/celery/tree/3.1/examples/django</a> . In settings after const BROKER_URL I added </p>
  
  <pre><code>CELERY_RESULT_BACKEND = 'amqp://'
  </code></pre>
  
  <p>I'm trying task called 'add' from the project. Inside worker terminal result is ok but can't get it back. I call command something like this:</p>
  
  <pre><code>from demoapp.tasks import add
  add.delay(2,2)
  add.AsyncResult(a.task_id).get()
  </code></pre>
  
  <p>But don't know why I get error:</p>
  
  <pre><code>&lt;ipython-input-3-5f18de09f6a1&gt; in &lt;module&gt;()
  ----&gt; 1 add.AsyncResult(a.task_id).get()
