This edition of this award-winning classic has been reorganized and refocused so it’s more useful than ever before for developers new to Ruby and Rails.

Rails 3 was a major release—the changes weren’t just incremental, but structural. So we decided to follow suit. This book isn’t just a mild reworking of the previous edition to make it run with the new Rails. Instead, it’s a complete refactoring.

You’ll still find the Depot example at the front, but you’ll also find testing knitted right in. Gone are the long reference chapters—that’s what the web does best. Instead you’ll find more targeted information on all the aspects of Rails you’ll need to be a successful web developer.

This edition is for Rails 3.2. It has been replaced with the Rails 4.0 Edition.

Ruby on Rails helps you produce high-quality, beautiful-looking web applications quickly. You concentrate on creating the application, and Rails takes care of the details.

Tens of thousands of developers have used this award-winning book to learn Rails. It’s a broad, far-reaching tutorial and reference that’s recommended by the Rails core team. If you’re new to Rails, you’ll get step-by-step guidance. If you’re an experienced developer, this book will give you the comprehensive, insider information you need.

Rails has evolved over the years, and this book has evolved along with it. We still start with a step-by-step walkthrough of building a real application, and in-depth chapters look at the built-in Rails features. This edition now gives new Ruby and Rails users more information on the Ruby language and takes more time to explain key concepts throughout. Best practices on how to apply Rails continue to change, and this edition keeps up.

For Rails 3.2
