Replacing RoR default prototype library with Jquery Via Jquery-Rails Gem

RoR is shipped with Prototype javascript library, it's pretty rich in feature and when its combine with scriptaculous it brings awesome javascript effects to your rails app.
Having use both prototype and jquery, i find jquery little less verbose.
After all, write less and do more should be given more preference.

Here are steps to replace prototype with jquery using a gem christened 'jquery-rails' .

In your  GemFile  add this one more gem


gem 'jquery-rails'



once done adding, run your rails 3 bundler
$ bundle install

Confirm installation of jquery-rails gem:
$ gem list 
# if you find 'jquery-rails' in the this list, you're good to go ,otherwise,  confirm gemfile content.

Now, install jquery
$ rails generate jquery:install  
# g is short tag for generate

sahilsk@dragonaider:~/cronfarm$ rails g jquery:install
