About

This extension enables you to store Celery task results using the Django ORM.

It defines a single model (django_celery_results.models.TaskResult) used to store task results, and you can query this database table like any other Django model.

Installing

The installation instructions for this extension is available from the Celery documentation:

http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html#django-celery-results-using-the-django-orm-cache-as-a-result-backend

Issues with mysql

If you want to run django-celery-results with MySQL, you might run into some issues.

One such issue is when you try to run python manage.py migrate django_celery_results, you might get the following error:

django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 767 bytes')

To get around this issue, you can set:

DJANGO_CELERY_RESULTS_TASK_ID_MAX_LENGTH=191

(or any other value if any other db other than MySQL is causing similar issues.)

max_length of 191 seems to work for MySQL.
