Online or not?

Rails
1

Hey,
I’m using this to see who’s online on a intranet site at work.

def get_online_users
sessions = CGI::Session::ActiveRecordStore::Session.find(:all,
:conditions => [“updated_at >= ?”, 30.minutes.ago])
user_ids = sessions.collect{|s| s.data[:user_id]}.compact.uniq
online_users = User.find(user_ids, :select => “screen_name”)
return online_users
end

It all works fine and returns a list of who is online at any given
time(with 30mins delay)

Now I’d like to show a “online now” badge on the actual user profile,
how could I compare this online_user object to see if a given user is
present in this online_user object?

Pretty basic I suppose but I’m only a noob!

Thank you
Oli

get_online_users.include?(some_user) (you’ll need to make your :select
include the id column for this to work)

You could save yourself a database hit (and instantiating a user
object for each online user) by having a method that just returns the
user_ids. You could then do something like user_ids.include?
(some_user.id)
