celery, postgresql -> configure backend
backend, celery, python
Solution
The answer lies here http://celery.readthedocs.org/en/latest/configuration.html#database-url-examples
You need to prefix your regular SQL Alchemy url string with `db+`, such as
CELERY_RESULT_BACKEND = "db+postgresql+psycopg2://..."
Problem
So i'm just getting started with celery and trying to do some simple tests to get a feel for it. Im trying to set a celery to use postgres for my backend. on this page: http://docs.celeryproject.org/en/latest/getting-started/first-steps-with-celery.html#keeping-results I see the example ``` celery = Celery('tasks', backend='redis://localhost', broker='amqp://') ``` So in my code I try ``` celery = Celery('tasks', backend='sqla+postgresql://celery_exp:celery_exp@myhost/celery_exp', broker='sqla+postgresql://celery_exp:celery_exp@myhost/celery_exp',) ``` but i keep getting this error when starting it: ``` ImportError: No module named sqla+postgresql ``` In the docs I've tried different variations such as ``` postgresql:// postgresql+psycopg2:// ``` I know that the connection string is correct besause taking out the backend paramter in the Celery constructor works as expected. What am i doing wrong here? I feel it must be something stupid because I can't find anything on the net. thanks in advance.
