Ruby for Rails teaches the Ruby programming language to readers whose main interest in Ruby is working with the popular Ruby on Rails web application development framework. Rails itself is written in Ruby and Rails application code is Ruby code. With this book's focus on the Ruby language, its programming techniques and idioms, web developers will be able to expand the understanding and the power of what they can do in Rails. Anyone who's approached Ruby only after first jumping into Rails will want to flesh out the picture. Newcomers to Ruby and Rails will get valuable preparation for Rails development from this book by gaining a solid, Rails-aware Ruby foundation. Seasoned Rails programmers who know the common Ruby techniques in Rails will want to go further-they will gain knowledge and momentum from this book.
