4. Celery tasks

The best way to keep your content up-to-date is by running a Celery worker that will update and cache all the plugins.

It’s easy to get it up and running.

  1. Install the django-celery library:

    pip install django-celery
  2. Add the following lines to settings.py:

    import djcelery
  3. Add ‘djcelery’ to INSTALLED_APPS.

  4. syncdb or migrate if you’re using south:

    python manage.py migrate djcelery
  5. Configure your tasks in settings.py:

    BROKER_URL = 'amqp://guest:guest@localhost:5672/' # if you're using RabbitMQ
    CELERY_IMPORTS = ("goscale.tasks", )
  6. If you want a task to update GoScale plugins to be sent immediately after plugin was saved in the Django admin add this in your settings:

  7. If you want to setup a schedule for updating, configure Celery Beat:

    from celery.schedules import crontab
    CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler' # or whatever you prefer
        "update_goscale_plugins": {
            "task": "goscale.tasks.update_goscale_plugins",
            "schedule": crontab(minute='*/30'), # every 30 minutes
            "args": ()
  8. Run your worker and celery beat:

    python manage.py celery worker -B

For more detailed information refer to Celery documentation.
