SessionExpirationManagement

Introduction

Most of the bank sites log you out or allow you to extend your session if you are inactive for a while. This plugin provides an opportunity to user to extend his/her session before logging the user out.

jQuery 1.3+

Rails 2.3

Why I am not using some sort of modal box

When I use modal box then set_Timeout function doest not work properly. Until I find out how to fix that, this is the best I could do.

How to install

ruby script/plugin install git://github.com/neerajdotname/session_expiration_management.git 

Copy the javascript file to your application

cp vendor/plugins/session_expiration_management/lib/js/session_about_to_expire.js public/javascripts

Inside the head tag of your layout add following two lines

<%= javascript_include_tag 'session_about_to_expire' %>
<%= trigger_session_expiration_watch %>

In application_controller.rb add followling line

 manage_session_expiration(:logout_url => '/logout')

By default user will be logged out if user is inactive for 20 minuts. 2 minutes before that usre will be prompted to extend their session. If you want to override the default values then you can provide your values like this

manage_session_expiration(:logout_url => '/logout',
                          :keep_session_alive_for => 30.minutes,
                          :warn_user_when_time_left_is => 4.minutes)

Thie plugin assumes that view has access to method logged_in?. Usually I define this method like this in application_controller.rb

def logged_in?
  session[:user_id]
end
helper_method :logged_in?
