django celery beat DBAccessError

I am running django+celery with celerybeat, and i am getting this error

.../local/lib/python2.7/site-packages/celery/beat.py", line 367, in setup_schedule
    writeback=True)
  File "/usr/lib/python2.7/shelve.py", line 239, in open
    return DbfilenameShelf(filename, flag, protocol, writeback)
  File "/usr/lib/python2.7/shelve.py", line 223, in __init__

I used python manage.py celeryd -B to run celery beat. It seems that running the celery worker is not the issue, but the celerybeat worker is not initialising. any suggestions as to where i could find the database which celery is trying to access?

I'm running django=1.5 and django-celery==3.1.10

I asked too soon!

answering my own question in case anyone else face the same issue.

The issue was because I did not have write permission in the folder my django project was running.

from the documentation (http://celery.readthedocs.org/en/latest/userguide/periodic-tasks.html#starting-the-scheduler)

Beat needs to store the last run times of the tasks in a local database file (named celerybeat-schedule by default), so it needs access to write in the current directory

fixed the issue by running

python manage.py celeryd -B -s /path/to/where/i/have/write-access/celerybeat-schedule

Hope that this helps someone.
