Reviews

Praise for the Previous Edition This encyclopedic book is not only a definitive Rails reference, but an indispensable guide to Software-as-a-Service coding techniques for serious craftspersons. I keep a copy in the lab, a copy at home, and a copy on each of my three e-book readers, and it's on the short list of essential resources for my undergraduate software engineering course. --Armando Fox, adjunct associate professor, University of California, Berkeley Everyone interested in Rails, at some point, has to follow The Rails Way. --Fabio Cevasco, senior technical writer, Siemens AG, and blogger at H3RALD.com 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 our a pro on the other side. --Dirk Elmendorf, co-founder of Rackspace, and Rails developer since 2005 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 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, McLatchy Interactive; former editor-in-chief of Linux Magazine Hal Fulton's The RubyWay 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 As noted in my contribution to the Afterword: What Is the Rails Way (To You)?, 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, InfoQ.com, .NET and Ruby community editor, and founding member of the Hartford, CT, 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
