Rails just keeps on changing. Both Rails 3 and 4, as well as Ruby 1.9 and 2.0, bring hundreds of improvements, including new APIs and substantial performance enhancements. The fourth 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 4 introduces a number of user-facing changes, and the book has been updated to match all the latest changes and new best practices in Rails. This includes full support for Ruby 2.0, controller concerns, Russian Doll caching, strong parameters, Turbolinks, new test and bin directory layouts, and much more.
When I started learning Ruby on Rails, I read the first edition of this book. Its holistic view of the Rails framework and community provides any new developer the kick start they need to a highly successful career. After reading through the latest edition cover to cover, I can happily say that it continues that trend and remains the first book I recommend to any new Rails developer.

Agile Web Development with Rails does an excellent job of making the Rails environment accessible in an enjoyable and memorable way. In addition, this book is the first I’ve seen that provides a sensible and coherent explanation of the MVC pattern, and it does so in a natural progression using examples that completely remove any mystery.

Agile Web Development with Rails successfully straddles a fine line between being a fun-to-read introduction to Rails (and Ruby) and a straightforward guide to some advanced features of the platform, nicely supplanting the everchanging online documentation.

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. Examples use Concerns, Russian Doll caching, and Turbolinks, and the book focuses throughout on the right way to use Rails. Additionally, this edition now works on Ruby 2.0, a new release of Ruby with substantial functional and performance improvements.
In this online, self-paced course you’ll learn the fundamentals every Rails developer should know, and how to put all the pieces together, so you can confidently create your first Rails app or jump right into an existing app. Throughout the course you’ll also learn key design principles and practices to help you craft robust and flexible Rails apps.
“One of the best learning experiences I’ve ever had! I’ve gone through many courses and books. From all of these, your Rails course is the best in terms of teaching style, course structure, topics, and being up-to-date with Rails 4.” — Mate Kaszas
