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
   djcelery.setup_loader()
   

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:

   GOSCALE_UPDATE_FROM_ADMIN = True
   

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
   
   CELERYBEAT_SCHEDULE = {
       "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
