A Flickr-Based Introduction to Ruby on Rails 2.0

Rails web application framework became the perfect killer application for the Ruby language and an extremely powerful tool for rapidly developing web applications based on the CRUD (Create, Read, Update, Delete) pattern. At the end of 2007, version 2.0 of the now popular web application framework was released. Although not as groundbreaking as the first release, Rails 2.0 still offers many innovations that make developing with it more productive and fun. This paper describes how to get started with Rails 2.0, explores some of the most prominent new features, and uses them to show how to build a simple, but visually attractive, web application.
