Product Description


Praise for The Rails Way


"For intermediates and above, I strongly recommend adding this title to your technical bookshelf. There is simply no other Rails title on the market at this time that offers the technical depth of the framework than The Rails™ 3 Way."

—Mike Riley, Dr. Dobb’s Journal


"I highly suggest you get this book. Software moves fast, especially the Rails API, but I feel this book has many core API and development concepts that will be useful for a while to come."

—Matt Polito, software engineer and member of Chicago Ruby User Group


"This book should live on your desktop if you’re a Rails developer. It’s nearly perfect in my opinion."

—Luca Pette, developer


"The Rails™ 3 Way is likely to take you from being a haphazard poke-a-stick-at-it programmer to a deliberate, skillful, productive, and confident RoR developer."

—Katrina Owen, JavaRanch


"I can positively say that it’s the single best Rails book ever published to date. By a long shot."

—Antonio Cangiano, software engineer and technical evangelist at IBM


"This book is a great crash course in Ruby on Rails! It doesn’t just document the features of Rails, it filters everything through the lens of an experienced Rails developer—so you come out a pro on the other side."

—Dirk Elmendorf, cofounder of Rackspace Inc. and Rails developer


"The key to The Rails Way is in the title. It literally covers the 'way' to do almost everything with Rails. Writing a truly exhaustive reference to the most popular web application framework used by thousands of developers is no mean feat. A thankful community of developers that has struggled to rely on scant documentation will embrace The Rails Way with open arms. A tour de force!"

—Peter Cooper, editor, Ruby Inside: The Ruby Blog


"In the past year, dozens of Rails books have been rushed to publication. A handful are good. Most regurgitate rudimentary information easily found on the Web. Only this book provides both the broad and deep technicalities of Rails. Nascent and expert developers, I recommend you follow The Rails Way."

—Martin Streicher, chief technology officer, McClatchy Interactive, former editor in chief of Linux Magazine


"Hal Fulton’s The Ruby Way has always been by my side as a reference while programming Ruby. Many times I had wished there was a book that had the same depth and attention to detail, only focused on the Rails framework. That book is now here and hasn’t left my desk for the past month."

—Nate Klaiber, Ruby programmer


"I knew soon after becoming involved with Rails that I had found something great. Now, with Obie’s book, I have been able to step into Ruby on Rails development coming from .NET and be productive right away. The applications I have created I believe to be a much better quality due to the techniques I learned using Obie’s knowledge."

—Robert Bazinet,, .NET, and Ruby community editor and founding member of the Hartford Ruby Brigade


"Extremely well written; it’s a resource that every Rails programmer should have. Yes, it’s that good."

—Reuven Lerner, Linux Journal columnist

The best Rails 4.1 reference book 3 Jun 2014
By Josh - Published on
Format: Paperback
I'm always suspicious when I see many positive reviews of a product posted immediately after the product is listed at Amazon. I assume the reviews are written by the creators and maybe their friends and family. But in the case of The Rails 4 Way, the initial positive reviews are likely written by people like me and the reviewer named kamera who have been happily reading DRM-free digital copies of The Rails 4 Way that we bought months ago.

As I wrote in my negative review of another Rails book listed at Amazon, The Rails 4 Way has great coverage of all the new features in Rails 4 (unlike certain Rails books). Also, The Rails 4 Way has been updated to include coverage of Rails 4.1 features, including Spring, secrets.yml, etc. I'm surprised that the Book Description section here at Amazon doesn't mention Rails 4.1.

I buy just about every Rails book that's published and I toss them all in a directory that's indexed for full-text searching. In the past, when I wanted more info about a Rails feature than what is provided by the official Rails documentation and Rails Guides, I searched my library of books. But lately, when I want more info, I just open The Rails 4 Way. It usually has what I'm looking for. As the introduction of The Rails 4 Way states, "This book is not a tutorial or basic introduction to Ruby or Rails. It is meant as a day-to-day reference for the full-time Rails developer." This is how I use The Rails 4 Way, and it's the best Rails reference book I own.

My only complaint is that my DRM-free PDF edition of The Rails 4 Way doesn't include an index. I see that the print edition does include a index, but the preview of the Kindle edition doesn't show an index. If you plan to buy the Kindle edition and you want an index, I'd recommend contacting the publisher to ensure that an index is included in the Kindle edition.

is a great reference book that covers most of what a Rails ... 13 Sep 2014
By Y. Segal - Published on
Format: Paperback
"The Rails 4 Way", is a great reference book that covers most of what a Rails developer is likely to need on a daily basis. It covers the various DSLs and idioms (i.e. route definition, controller filter declaration, ActiveModel association and validations, etc) without getting into the details of Rails internals and how those features are implemented. The explanations are clear and the code examples relevant.

Just like Rails itself, "The Rails 4 Way" is opinionated and occasionally differs from the omakase way; Most notoriously, but hardly controversial, using Haml as a template engine and Rspec for testing.

Most of the book can be read cover-to-cover or used as a reference on particular topics. The exception is section about rails helpers (Chapter 11) which, as the author themselves point out, is really just an alphabetical listing of the methods available, like the one usually found on appendices or online documentation.

I recommend this book to new Rails developers (maybe after trying out an online tutorial) and for experienced Rails developers who are still working on Rails 3 (or 2!) and are expecting to make the jump to Rails 4 in the near future.

By Elmer A. Sia - Published on
Format: Paperback Verified Purchase
I bought this book to be my go-to reference book for Rails 4 development. I love everything that I'm reading so far, and I believe this book is truly indispensable for the full-fledged Rails developer.

Great intro to Rails 30 July 2014
By julio - Published on
Format: Kindle Edition Verified Purchase
Clear examples, up to date text (at the moment, anyway!) and surprisingly everything worked-- no need to go the web for workarounds and updates. Good resource.
