[Solved]-Rake:task equivalent in Django

Also look at setting up a custom subcommand for your manage.py.

Try this: django-tasks

May be celery would be better in this case.

Because as stated in django-tasks page:

Django-tasks is for a different usage
from most other tasks frameworks
(Celery, Cue…): this is not for
numerous, quick, light, tasks, but for
few, long, heavy, tasks. Typical usage
is to batch process data for each
model object, and give information
about the processing to the user.

So it depends on the purpose.

Although it is more commonly used for application deployment and system administration, Fabric might be interesting.
