Set up a scheduled job?
One solution that I have employed is to do this:
1) Create a custom management command, e.g.
python manage.py my_cool_command
cron (on Linux) or
at (on Windows) to run my command at the required times.
This is a simple solution that doesn't require installing a heavy AMQP stack. However there are nice advantages to using something like Celery, mentioned in the other answers. In particular, with Celery it is nice to not have to spread your application logic out into crontab files. However the cron solution works quite nicely for a small to medium sized application and where you don't want a lot of external dependencies.
In later version of windows the
at command is deprecated for Windows 8, Server 2012 and above. You can use
schtasks.exe for same use.
**** UPDATE ****This the new link of django doc for writing the custom management command
Celery is pretty easy to set up with django (docs), and periodic tasks will actually skip missed tasks in case of a downtime. Celery also has built-in retry mechanisms, in case a task fails.
We've open-sourced what I think is a structured app. that Brian's solution above alludes too. We would love any / all feedback!
It comes with one management command:
That does the job. Each cron is modeled as a class (so its all OO) and each cron runs at a different frequency and we make sure the same cron type doesn't run in parallel (in case crons themselves take longer time to run than their frequency!)
