The Rails 4 Way (3rd Edition)

The “Bible” for Rails Development: Now Fully Updated for Rails 4.1
"When I read The Rails Way for the first time, I felt like I truly understood Rails for the first time.”
—From the Foreword by Steve Klabnik
Ruby on Rails 4 is leaner, tighter, and even more valuable to professional web developers. More than ever, it helps you focus on what matters most: delivering business value via clean and maintainable code.
The Rails™ 4 Way is the only comprehensive, authoritative guide to delivering production-quality code with Rails 4. Kevin Faustino joins pioneering Rails developer Obie Fernandez to illuminate the entire Rails 4 API, including its most powerful and modern idioms, design approaches, and libraries. They present extensive new and updated content on security, performance, caching, Haml, RSpec, Ajax, the Asset Pipeline, and more.
Through detailed code examples, you’ll dive deep into the Rails 4 code base, discover why Rails is designed as it is, and learn how to make it do exactly what you want. Proven in dozens of production systems, this book’s techniques will maximize your productivity and help you build more successful solutions.
