Database Session Sets user_id to null...

Hi all,

I'm using database session driver, to register all users online. The problem is that I also want to register the last_activity of all users. But the database Session Sets user_id to null when user logs out, so I can't retrieve the users last_activity.

I'm not sure what is the best way to tackle this. Do I have to make a custom session driver? or is there a simpler approach?

Thanks
