Nick,

Have a look at the Beast project code:

```
   http://svn.techno-weenie.net/projects/beast/
http://beast.caboo.se/forums/1/topics/4

```

Usage (in view)  
…  
Guests online: \<%= Session.active\_count %\>  
…

Implementation:

file: model/session.rb  
Session = CGI::Session::ActiveRecordStore::Session  
Session.class\_eval do  
def self.active\_count  
count(:all, :conditions =\> [“updated\_at \> ?”,  
Time.now.utc-5.minutes])  
end  
end

! it requires you store sessions in the db :

=\> in environment.rb, uncomment:  
…  
config.action\_controller.session\_store = :active\_record\_store  
…
