I am trying to use django-celery in my project

In settings.py I have

```
CELERY_RESULT_BACKEND = "amqp"

```

The server started fine with

```
python manage.py celeryd --setting=settings

```

But if I want to access a result from a delayed task, I get the following error:

```
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\celery\result.py", line 108, in ready
    return self.status in self.backend.READY_STATES
  File "C:\Python27\lib\site-packages\celery\result.py", line 196, in status
    return self.state
  File "C:\Python27\lib\site-packages\celery\result.py", line 191, in state
    return self.backend.get_status(self.task_id)
  File "C:\Python27\lib\site-packages\celery\backends\base.py", line 404, in _is
_disabled
    raise NotImplementedError("No result backend configured.  "
NotImplementedError: No result backend configured.  Please see the documentation
 for more information.

```

It is very strange because when I just run celeryd (with the same celery settings), it works just fine. Has anyone encountered this problem before?

Thanks in advance!
