Rails 3 in Action (Paperback)

Rails 3 in Action takes you on a journey developing a Rails application in the real world, one step at a time. This collaboration between Rails community leaders Ryan Bigg and Yehuda Katz book covers Rails 3.1 so it's the most up-to-date resource available. But it's much more than just a Rails 3 reference book. You'll learn to do Rails the right way so you can build stable, scalable, and maintainable apps that will satisfy even the most demanding clients.

Rails 3 in Action introduces the core concepts and techniques of Ruby on Rails by developing an application and demonstrating how it works. If you're a beginner, you'll catch on quick. If you have a few cycles under your belt already, you'll appreciate seeing this gurus-eye-view of Rails basics. Early on you begin delving into two core principles: Test Driven Development (TDD) and Behavior Driven Development (BDD). You'll apply these practices throughout the book, just like you would in the top Rails shops worldwide.

You'll explore Rails 3 by developing a ticket tracking application that includes:

• RESTful routing
• Authentication & Authorization Systems
• Using RSpec & Cucumber
• The basics of a maintainable Rails application

There's more than that though! You'll also tackle more advanced issues.

• Chapter 16 begins the departure from the application development and moves into developing a miniature application, called an engine. This is a relatively new feature in Rails 3.1, and this chapter is the most comprehensive guide to engine development with Ruby on Rails 3.1 available.
• Chapter 17 covers Rack applications and how to work with Rack middleware. Rack is a key component of how the entire Rails stack works, and this chapter provides great detail on how Rack ties into Rails.

Rails 3.1 and the evolving ecosystem around it introduces a new generation of Rails development. Whether you're just starting with Rails or moving from an earlier version, this book is a must-read.
