David A. Black’s book Ruby for Rails is now available in full in PDF form (paper copy scheduled to follow the first week of May). The book covers the ins and outs of Ruby with a focus on Rails. It is aimed at Rails developers who want to gain a deeper understanding of Ruby beyond what Rails builds on top of it.

Taking a look at the table of contents you’ll get a sense of how much territory the book covers. There are two sample chapers for free. One is on Organizing objects with classes and the other on Scalar objects.

David Black is an ideal guide through Ruby, having been a member of the community for over 5 years and as the director of Ruby Central, the not for profit organization that brings you RubyConf every year.

It’s no secret that Ruby is one of the key ingredients in Rails’ special sauce. If you are a Rails developer, you owe it to yourself to be a Ruby master. Ruby for Rails is a great place to start.
