How to lookup django session for a particular user?

Question

I am writing an application where I will be accessing the database from django and from a stand alone application. Both need to do session verification and the session shoul

Peter Rowell, thanks for your response. It was a tremendous help. This is what I did to get it working. Only had to change one file in djang.contrib.sessions.

In django/contrib/sessions/models.py, add the user_id to the table (add to DB table manually or drop table and run manage.py syncdb).

class Session(models.Model):

    ...

    user_id = models.IntegerField(_('user_id'), null=True)

    ...

    def save(self, *args, **kwargs):
        user_id = self.get_decoded().get('_auth_user_id')
        if ( user_id != None ):
            self.user_id = user_id

        # Call the "real" save() method.
        super(Session, self).save(*args, **kwargs)

Now in your view where you do login (if you use django's base login, you will have to override it)

# On login, destroy all prev sessions
        # This disallows multiple logins from different browsers
        dbSessions = Session.objects.filter( user_id = request.user.id )
        for index, dbSession in enumerate( dbSessions ):
            if ( dbSession.session_key != request.session.session_key ):
                dbSession.delete()

This worked for me.
