Django: signal when user logs in?

Question

In my Django app, I need to start running a few periodic background jobs when a user logs in and stop running them when the user logs out, so I am looking for an elegant way

Answer 1

You can use a signal like this (I put mine in models.py)

from django.contrib.auth.signals import user_logged_in


def do_stuff(sender, user, request, **kwargs):
    whatever...

user_logged_in.connect(do_stuff)

See django docs: https://docs.djangoproject.com/en/dev/ref/contrib/auth/#module-django.contrib.auth.signals and here http://docs.djangoproject.com/en/dev/topics/signals/
