How to run cron-like scripts on Django?

Question

To give you a little brief about what I'm tying to do ->
I'm building a timed-contest app which expires at a set datetime.
So basically I want a script which queries my model and changes some values according to busines logic periodically

How would you do this in django ?

Answer 1

You use celery.

Answer 2

You wouldn't. You'd use cron to run a standalone script or management command.
