Rails - Jun 2006 - Can I peek at all "active sessions"?

My users need to login to run the app I''m building.  I''d like
to give
them an "Other users currently active:" piece of information.  I could
track it myself in the database based on login/logout, but that doesn''t
really count for people just leaving the computer logged in and never 
coming back.  Does Rails have an API for me to monitor sessions and take 
a peek at their info?

I''m googling as best I can but I have to sift through all the
references
to developer conferences with "ruby sessions" :)

That can be done (see my post about "SessionCleanup" -- a look at the 
software will give you a good idea how to go about it).

BUT -- it''s not any more useful than tracking logins and logouts. 
Sessions can''t tell you when somebody wanders away from a computer and 
doesn''t come back.

Probably the best approach would be to keep a database record of people 
presently logged in with a "last_activity_time" field, and update it 
whenever they performed some activity. Then you could present a list of 
everyone who had done something in the past ten minutes, for example.

This would work pretty easily.  Add a column to the sessions table,
then a before_filter in application.rb to update the field.  This
wouldn''t work if your users viewed only cached pages for X consecutive
minutes, but it should be close enough (if that''s even an issue).

Sure, here''s how.  Create a file called dump_sessions (no .rb
extension)
in your /script subdirectory.  Paste the following code:

#!/usr/bin/env ruby
require ''pp''
require File.dirname(__FILE__) + ''/../config/environment''
Dir[''app/models/**/*rb''].each{|f| require f}
pp Dir[''./tmp/sessions/ruby_sess*''].collect {|file| [file,
Marshal.load(File.read(file))] }

Now, from the root of your app, type ruby script/dump_sessions and there
you have it.  :)

If you use DB Sessions you can add a before filter in application.rb to set
some session variable, make sure you have a DB column updated_at, and then
just query that field.
