Take a step forward to be a Rails 3 expert: Get it nowMuch of the work of Rails 3 involved significant improvements to its APIs. If you want to learn more about how to use them in a practical way, this book is a must read.
- Yehuda Katz
Rails 3 is a huge step forward. You can now easily extend the framework, change its behavior, and replace whole components to bend it to your will, all without messy hacks. This pioneering book is the first resource that deep dives into the new Rails 3 APIs and tells you how use them to write better web applications and make your day-to-day work with Rails more productive.
Rails Core developer José Valim guides you through seven different tutorials, each of them using test-driven development to build a new Rails extension or application that solves common problems with these new APIs. You will understand how the Rails rendering stack works and customize it to read templates from the database while you learn how to mimic Active Record behavior, like validations, in any other object. You will find out how to write faster, leaner controllers, and you'll learn how to mix Sinatra applications into your Rails apps, so you can choose the most appropriate tool for the job. In addition, you will improve your productivity by customizing generators and responders.
This book will help you understand Rails 3 better so you can use its structure to write simpler, faster, and better web applications.

Lately, he's been flying around the globe giving talks and courses about Ruby and Rails.
Not many books have been written for more advanced Rails developers. This book steps into that space and covers totally new ground with practical techniques that can be put to use right away. Great stuff.

This book cuts through the hype surrounding Rails 3 and teaches you practical techniques to take advantage of the modularity and extensibility that we've heard so much about.
- Trevor Turk, Freelance Developer
Great coders who can clearly explain their code are rare but José shows he is one of the rare ones. This book taught me about the way Rails works, how to exploit its new flexibility and how I can leverage my effort substantially. If you plan to do more than just write apps with Rails, read this book.
