Demystifying Rails by Launch School

This book doesn't teach how to use Rails to build prototypes. Instead, this book dives one layer below the surface to expose how Rails is pieced together. We'll take common Rails conventions apart and study each component from the perspective of web development fundamentals. Significant programming, web development, and even basic Rails knowledge will be helpful prior to starting this book. This book also supplements the material in our course, "Rapid Prototyping with Ruby on Rails"
