Michael Hartl’s Rails Tutorial is the # 1 (and, in my opinion, the only place to start) when it comes to books on Rails learning… It’s an amazing job and unusually guides you through building a Rails app from start to finish with testing. If you want to read just one book and feel like a Rails master in the end, choose the Ruby on Rails Tutorial.
-Peter Cooper, editor, Ruby Inside “Founded in the real world”.
-I Programmer (www.i-programmer.info), by Ian Elliot The book gives you the theory and practice, while the videos focus on showing you in person how it’s done. Highly recommended combo.
-Antonio Cangiano, software engineer, IBM “The author is clearly an expert in the Ruby language and the Rails framework, but more than that, he is a software engineer who presents best practices throughout the text.”
-Greg Charles, Senior Software Software, Fairway Technologies “Overall, these video tutorials are a great resource for anyone new to Rails.”
-Michael Morin, ruby.about.com “I would definitely recommend this book to anyone who wants to get into Ruby on Rails development”. -Michael Crump, Microsoft MVP
