django-celery - Celery Integration for Django
|Keywords:||celery, task queue, job queue, asynchronous, rabbitmq, amqp, redis, python, django, webhooks, queue, distributed|
django-celery provides Celery integration for Django; Using the Django ORM and cache backend for storing results, autodiscovery of task modules for applications listed in INSTALLED_APPS, and more.
Celery is a task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well.
The execution units, called tasks, are executed concurrently on a single or more worker servers. Tasks can execute asynchronously (in the background) or synchronously (wait until ready).
Celery is already used in production to process millions of tasks a day.
Celery is written in Python, but the protocol can be implemented in any language. It can also operate with other languages using webhooks.
To enable django-celery for your project you need to add djcelery to INSTALLED_APPS:
INSTALLED_APPS += ("djcelery", )
Then add the following lines to settings.py:
import djcelery djcelery.setup_loader()
Everything works the same as described in the Celery User Manual, except you need to invoke the programs through manage.py:
|celeryd||python manage.py celeryd|
|celerybeat||python manage.py celerybeat|
|camqadm||python manage.py camqadm|
|celeryev||python manage.py celeryev|
The other main difference is that configuration values are stored in your Django projects' settings.py module rather than in celeryconfig.py.
If you're trying celery for the first time you should start by reading Getting started with django-celery
