Question

I began using celery 3.1.9 today with Django. This newer version has a tighter integration with django that removes the need to using django-celery.

Answer 1

A solution is to use environment variables.

In celery.py

Instead of

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings')

use

os.environ.setdefault('DJANGO_SETTINGS_MODULE', '{0}'.format(get_env_setting('DJANGO_SETTINGS_MODULE')))

With get_env_setting defined as:

from os import environ
from django.core.exceptions import ImproperlyConfigured

# https://github.com/twoscoops/django-twoscoops-project/blob/develop/project_name/project_name/settings/production.py#L14-L21
def get_env_setting(setting):
    """ Get the environment setting or return exception """
    try:
        return environ[setting]
    except KeyError:
        error_msg = "Set the %s env variable" % setting
        raise ImproperlyConfigured(error_msg)

You could put that in your settings.base.py e.g. .

Then set the DJANGO_SETTINGS_MODULE environment variable for each environment. E.g. set it to my_project.settings.production in the production environment. This variable can by permanently set by adding the following line to ~/.bashrc:

export DJANGO_SETTINGS_MODULE=my_project.settings.production

Answer 2

When initializing the celery worker on the command line, just set the environment variable prior to the celery command.

DJANGO_SETTINGS_MODULE='proj.settings' celery -A proj worker -l info
