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

In addition to @PhoebeB answer: you can also use @receiver decorator like this:

from django.contrib.auth.signals import user_logged_in
from django.dispatch import receiver

@receiver(user_logged_in)
def post_login(sender, user, request, **kwargs):
    ...do your stuff..

And if you put it into signals.py in your app dir, then add this to apps.py:

class AppNameConfig(AppConfig):
    ...
    def ready(self):
        import app_name.signals
