If you’re a web developer or designer ready to learn Rails, this unique book is the ideal way to start.

Rather than throw you into the middle of the framework’s Model-View-Controller architecture, Learning Rails 3 works from the outside in. You’ll begin with the foundations of the Web you already know, and learn how to create something visible with Rails’ view layer. Then you’ll tackle the more difficult inner layers: the database models and controller code.

All you need to get started is HTML experience. Each chapter includes exercises and review questions to test your understanding as you go.

Present content by building an application with a basic view and a simple controller
Build forms and process their results, progressing from simple to more complex
Connect forms to models by setting up a database, and create code that maps to database structures
Use Rails scaffolding to build applications from a view-centric perspective
Add common web application elements such as sessions, cookies, and authentication
Build applications that combine data from multiple tables
Send and receive email messages from your applications

"Learning Rails 3 feels like a brisk pair programming session with professionals who know how to use Ruby on Rails to get things done, and get them done well."
-Alan Harris, author of Sinatra: Up and Running
