How does one enforce automatic logout due to inactivity in a Django application?

Question

In my Django application, I would like for the user to be automatically logged out after 30 minutes of inactivity, so I used this setting in settings.py:

SESSION_COOKIE_AGE = 1800

However, using this setting logs the user out in 30 minutes regardless of activity. How does one enforce automatic logout due to inactivity in a Django application?

Answer 1

You could update the session of an user when he accesses your site. For example in a middleware, this force session to be set again.

class ActivateUser(object):
    def process_request(self, request):
        if request.user.is_authenticated():
            request.session.modified = True
