Since David Heinemeier Hansson’s keynote speech at RailsConf 2006 and the release of Rails 1.2 in early 2007, Representational State Transfer, better known as REST, has taken the Rails world by storm. If you’re new to REST, this short cut will help you decide which parts of the REST paradigm you want to introduce to your application. If you’re a developer with more RESTful experience, this short cut will introduce you to some refactorings that will give your application a cleaner, leaner code base, while also serving as a reference to much of the functionality REST has brought to Rails.
