Obie Fernandez has been hacking computers since he got his first Commodore VIC-20 in the eighties, and found himself in the right place and time as a programmer on some of the first Java enterprise projects of the mid-nineties. Obie has been evangelizing Ruby on Rails online via blog posts and publications since early 2005. Since then, he has traveled around the world relentlessly promoting Rails at large industry conferences. As CEO and Founder of Hashrocket, Obie specializes in orchestrating the creation of large-scale, web-based applications, both for startups and mission-critical enterprise projects. He still gets his hands dirty with code on at least a weekly basis and posts regularly on various topics to his popular technology weblog blog.obiefernandez.com.
The Rails™ 3 Way is a comprehensive resource that digs into the new features in Rails 3 and perhaps more importantly, the rationale behind them.
—Yehuda Katz, Rails Core
The Bible for Ruby on Rails Application Development
Ruby on Rails strips complexity from the development process, enabling professional developers to focus on what matters most: delivering business value via clean and maintainable code. The Rails™ 3 Way is the only comprehensive, authoritative guide to delivering production-quality code with Rails 3. Pioneering Rails expert Obie Fernandez and a team of leading experts illuminate the entire Rails 3 API, along with the idioms, design approaches, and libraries that make developing applications with Rails so powerful. Drawing on their unsurpassed experience and track record, they address the real challenges development teams face, showing how to use Rails 3 to maximize your productivity.
Using numerous detailed code examples, the author systematically covers Rails 3 key capabilities and subsystems, making this book a reference that you will turn to again and again. He presents advanced Rails programming techniques that have been proven effective in day-to-day usage on dozens of production Rails systems and offers important insights into behavior-driven development and production considerations such as scalability. Dive deep into the Rails 3 codebase and discover why Rails is designed the way it is—and how to make it do what you want it to do.

A Rails 3.0 reference for experts, but a flawed champ.., By Peter Cooper (Louth, UK) - See all my reviews
This review is from: The Rails 3 Way (2nd Edition) (Addison-Wesley Professional Ruby Series) (Paperback)
The Rails 3 Way is an interesting book representing a large amount of effort digging into Rails 3. It shares insights and technical knowledge you'd struggle to patch together from blog posts and documentation. It's a very opinionated book and will not be to everyone's taste. For starters, ERb isn't covered at all, instance variables in views are scowled at, and Test::Unit is treated with contempt.It's not an introductory book in any sense and Obie acknowledges this in his introduction. Obie bills it as a "day-to-day reference for the full-time Rails developer" - a fair description IMHO, but the book feels disjointed in places and has a scattershot approach to what it cares to cover. You need to be clued up to digest this book properly. For an intermediate to expert Rails developer (especially one yet to move to Rails 3) or an expert Rubyist new to Rails, The Rails 3 Way is a useful book that unearths some of the trickier parts of Rails 3 a professional needs to know about...

Kindle version is unusable, By
Amazon Verified Purchase(What's this?)
This review is from: The Rails 3 Way (2nd Edition) (Addison-Wesley Professional Ruby Series) (Kindle Edition)
I have no issue with the contents of the book, only the Kindle implementation thereof.Listings and tables are converted to images, and some of those are so small that it is all but impossible to read on the Kindle. Unfortunately, the Kindle for PC version is even worse, the image rendering is pathetic, to say the least. I've bought 3 other Kindle books from the Addison-Wesley Professional Ruby Series as well, only Eloquent Ruby and Rails AntiPatterns can be read in their entirety on the Kindle, Service-Orientated Design with Ruby and Rails is as badly delivered as The Rails 3 Way. At least one can get some of the missing details by looking at the source code repositories for each book, but that is no excuse. If you buy a book (paper copy), surely the expectation is that all pages can be read?

Not a good reference, not a good intro, By
Amazon Verified Purchase(What's this?)
This review is from: The Rails 3 Way (2nd Edition) (Addison-Wesley Professional Ruby Series) (Paperback)
Had I written this review after about a month with this book, I would've given it very high marks. However, after several months with it, attempting to us it in a real Rails 3 project, I find it wanting.It's billed as a reference for Rails 3, and seems intended as something to have dog-eared, by your side, while cranking out a Rails app. In my experience over the last several months, it has been a source of frustration, providing me with little more than introductory information on topics that, sadly, are better covered by the rails guides or in various blog posts. The section on Active Record, specifically on querying, is very light. It's mostly a printout/summary of some of the methods available, with no substantive examples, or anything close to what might be required in the real world. AREL is barely mentioned; all we get is a link to the github page. There are two bigger disappointments: testing and AJAX. The AJAX section is not... Read more |
