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!
I had the same problem while getting the result back from the celery task although the celery task was executed ( console logs). What i found was, i had the same setting CELERY_RESULT_BACKEND = "redis"
in django settings.py but i had also instantiated celery in the tasks.py
celery = Celery('tasks', broker='redis://localhost')
- which i suppose overrides the settings.py property and hence it was not configuring the backend server for my celery instance which is used to store the results.
i removed this and let django get celery get properties from settings.py and the sample code worked for me.
