Ruby on Rails™ Tutorial: Learn Web Developments with Rails
ptg8286261 www.it-ebooks.info Praise for Michael Hartl’s Books and Videos on Ruby on RailsTM ‘‘My former company (CD Baby) was one of the first to loudly switch to Ruby on ptg8286261 Rails, and then even more loudly switch back to PHP (Google me to read about the drama). This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on RailsTM Tutorial is what I used to switch back to Rails again.’’ —From the Foreword by Derek Sivers (sivers.org) Formerly: Founder, CD Baby Currently: Founder, Thoughts Ltd. ‘‘Michael Hartl’s Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails. It’s an amazing piece of work and, unusually, walks 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 by the end of it, pick the Ruby on RailsTM Tutorial.’’ —Peter Cooper Editor, Ruby Inside www.it-ebooks.info ‘‘Grounded 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 its done. Highly recommended combo.’’ —Antonio Cangiano, Software Engineer, IBM ‘‘The author is clearly an expert at the Ruby language and the Rails framework, but more than that, he is a working software engineer who introduces best practices throughout the text.’’ —Greg Charles, Senior Software Developer, Fairway Technologies ‘‘Overall, these video tutorials should be a great resource for anyone new to Rails.’’ —Michael Morin, ruby.about.com ‘‘Hands-down, I would recommend this book to anyone wanting to get into Ruby on Rails development.’’ —Michael Crump, Microsoft MVP ptg8286261 www.it-ebooks.info RUBY ON RAILSTM TUTORIAL Second Edition ptg8286261 www.it-ebooks.info Visit informit.com/ruby for a complete list of available products. -
