When a user logs in, you could store Time.now in a field on the user
record in the db. When they log out, set the time to nil. When another
user is logging in, the login script should check to see how many users
are marked as "logged in", going back a certain amount of time. That
way
if someone happens to close their browser without logging off, you
won''t
have a zombie user attached to the system.
The only other thing you''d need to make this work is to update the last
touched time on the user throughout their use, so that someone already
logged in can''t become "logged out" just by using the site
for 30
minutes or whatever. Maybe stick an application-wide before_filter on
the site?
