Working With Rails

Balaji, does it mean you want to provide session expire time for your rails application? if so you can do it by adding a method with before filter in application.rb file.

prepend_before_filter :prepare_session
def prepare_session
   if !session[:expiry_time].nil? and session[:expiry_time] < Time.now
      reset_session
   end
   session[:expiry_time] = "set time to expire" 
 end

by mentioning specific time to expire the session, you do it.

Thank You,
Uma.

Hi Balaji,

If instead of a session expire time you are actually concerned about the number of useless session objects that get stored in your database by search engines there are a couple of options…

First, check out the build in rake tasks for sessions:

~/: rake -T | grep session
rake db:sessions:clear # Clear the sessions table
rake db:sessions:create # Creates a sessions migration for use with ActiveRecord::SessionStore
rake tmp:clear # Clear session, cache, and socket files from tmp/
rake tmp:create # Creates tmp directories for sessions, cache, sockets, and pids
rake tmp:sessions:clear # Clears all files in tmp/sessions

Second, there are plugins out there that can make the database-backed session store more intelligent. limited_sessions is one such plugin, I’m sure there are more out there.

Thanks for your inputs,

Kevin …...... The plugin seems to be the best shoot for this issue, especially the IP based check will help, but I’ll have to hunt for one that works in rails 1.2.3
