Want to learn all about Ruby on Rails 2.0, the web application framework that is inspiring developers around the world?

The second edition of this practical, hands on book will:

• show you how to install Ruby on Rails on Windows, Mac, or Linux
• walk you, step by step, through the development of a Web 2.0 social news application, just like digg.com
• show you how to test, debug, benchmark, and deploy your Rails application

Unlike other Rails books, this book doesn't assume that you are an experienced web developer, or that you've used Ruby before. An entire chapter is devoted to learning Ruby in a fun way, using the interactive Ruby console, so you can follow along at home. You'll be an accomplished Ruby programmer in no time!

The example application that the book builds - a user-generated news web site - is built upon with each following chapter, and concepts such as sessions, cookies and basic AJAX usage are gradually introduced. Different aspects of Rails, such as user authentication, session cookies, and automated testing are explored with each feature that is added to the application.

The book finishes with chapters on debugging, benchmarking and deployment to a live web server.

By the end of the book, you'll have built a fully-featured Web 2.0 application and deployed it to the Web. And all code is up-to-date for Rails 2.0, so you can begin coding immediately with the latest version of Rails.
