Rails has rapidly become one of the world's most popular web development frameworks. But Rails can be challenging - and, until now, there's been no good way to learn modern Rails development from the ground up. Ruby on Rails 3 Tutorial 2/e fills that enormous gap. Leading expert Michael Hartl teaches today's Rails best practices by walking readers through the construction of a complete application - from start to finish. Ruby on Rails 3 Tutorial 2/e is the first book to show developers how to take full advantage of the latest Rails 3.2 innovations - including techniques that make Rails development easier and more accessible. Hartl covers all facets of application design and implementation, addressing issues ranging from content management and e-commerce to CRM and Railscasts. Developers see each technique in real-world context, motivated by realistic problems. Hartl introduces new concepts at just the right pace, moving from the basics through advanced topics. The new edition has been updated to include: * Fully updated for Rails 3.2 and Ruby 1.9 * Coverage of the new asset pipeline * Behavior-driven development (BDD) with Capybara and RSpec * Introduction to Sass (Syntactically Awesome Stylesheets) * Better automated testing with Guard and Spork * Rolling your own authentication system with has_secure_password * An introduction to writing client-friendly tests with Cucumber
