Ruby on Rails Tutorial: Learn Rails by Example | by Michael Hart. My former company (CD Baby) was one of the first to loudly switch to Ruby on 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 Rails Tutorial is what I used to switch back to Rails again. Though I’ve worked my way through many Rails books, this is the one that finally made me “get” it. Everything is done very much “the Rails way”—a way that felt very unnatural to me before, but now after doing this book finally feels natural. This is also the only Rails book that does test-driven development the entire time, an approach highly recommended by the experts but which has never been so clearly demonstrated before.
Finally, by including Git, GitHub, and Heroku in the demo examples, the author really gives you a feel for what it’s like to do a real-world project. The linear narrative is such a great format. Enjoy! Derek Sivers (sivers.org) Founder, CD Baby. Ruby on Rails Quick Reference Guide. What is Ruby? Before we ride on Rails, let us recapitulate a few points of Ruby, which is the base of Rails.
