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.

We start with a step-by-step walkthrough of building a real application, and in-depth chapters look at the built-in Rails features. Follow along with an extended tutorial as you write a web-based store application; eliminate tedious configuration and housekeeping; internationalize your applications; incorporate Ajax, REST, web services, and e-mail handling into your applications; test your applications as you write them using the built-in testing frameworks; and deploy your applications easily and securely.

Rails has evolved over the years, and this book has evolved along with it. This book gives new Ruby 2.2 and Rails 5 users more information on the Ruby language and more background information alongside the book's sample application. Best practices on how to apply Rails continue to change, and this edition keeps up. Examples use cookie-backed sessions, HTTP authentication, and Active Record-based forms, and the book focuses throughout on the right way to use Rails.
