Rails just keeps on changing. Rails 3 and Ruby 1.9 bring hundreds of
improvements, including new APIs and substantial performance enhancements.
The fourth edition of this award-winning classic has been reorganized and
refocused so it.s more useful than ever before for developers new to Ruby
and Rails.

Rails 3 is a major release.the changes aren.t just incremental, but
structural. So we decided to follow suit. This book isn.t just a mild
reworking of the previous edition to make it run with the new Rails.
Instead, it.s a complete refactoring.

You.ll still find the Depot example at the front, but you.ll also find
testing knitted right in. Gone are the long reference chapters.that.s
what the web does best. Instead you.ll find more targeted information on
all the aspects of Rails that you.ll need to be a successful Web developer.

Now Updated for Rails 3.1
Rails 3.1 introduces a many user-facing changes, and this e-book release
has been updated to match all the latest changes and new best practices.
This includes full support for Ruby 1.9.2 hash syntax; incorporation of
the new Sprockets 2.0 Asset Pipeline, including SCSS and Coffeescript;
jQuery now being the default; reversible migrations; JSON response
support; Rack::Cache, and much more.
