Goodrich Glenn. Rails Deep Dive

SitePoint, 2012. — 146 p.Build a Rails Application from Scratch.
This book will guide you in creating a Rails application. It will focus on setting
your system up properly (for those systems that support it) and will fly a little lower
than the typical 50,000 foot level of many tutorials.(The book is smart, but keep in mind that it covers the RoR3 version)
