Unable to display celery tasks in djcelery admin (mongodb back end)

Question

my environment is composed of django, celery and mongodb as a back end.

I managed to create a periodic tasks using djcelery admin interface and after starting celerybeat I can see it runs. This task is simple: it just makes an addition of 2 integers as proposed in celery tutorial.

I launch celeryd with the following command line

python manage.py celeryd -E -l INFO --settings=settings

celerybeat with the following command line:

python manage.py celerybeat --settings=settings

and finally celerycam to take snapshots of my tasks:

python manage.py celerycam --settings=settings

When I try to display celery tasks in djcelery admin however I keep having the same error message, does anyone know how to fix it ?

Answer 1

MongoDB does not support advanced date/time lookups like __day, __year, __hour etc, this is why the date_hierarchy thing crashes.

However, the error message is pretty useless. Please open a ticket at https://github.com/django-nonrel/mongodb-engine/issues/ with a link to the full stacktrace (you can get that by clicking the "paste" button on the Django error page).

Possible workarounds:

1. Override the djcelery admin that causes the trouble, removing the date_hierarchy option
2. Use django-dbindexer to add support for these lookups by using denormalization.

Answer 2

In this question it stated that you should set specific Scheduler for the djcelery, but though I have configured this, my admin tasks page is empty (no exception, but does not get populated).

I'm using mysql as a storage for tasks.
