jRails is a drop-in jQuery replacement for the prototope-rails gem, so that you can still use RJS and Jquery/JqueryUi helpers with the same API as Prototype/Scryptaculous helpers.
Based on prototype-rails gem.
Support Rails 3.1+.
I've removed the tasks which added the jQuery and jQueryUI JS files as they were done manually and in asset pipeline it's handled automatically by the jquery-rails and jquery-ui-rails gems.
Add to your Gemfile
gem 'ftd-jrails'
