With this book, you'll learn how to use ActiveRecord to connect business objects and database tables. No more painful object-relational mapping. Just create your business objects and let Rails do the rest. Need to create and modify your schema? Migrations make it painless (and they're versioned, so you can roll changes backward and forward).

You'll learn how to use the Action Pack framework to route incoming requests and render pages using easy-to-write templates & components. See how to exploit the Rails service frameworks to send emails, implement web services, and create dynamic, user-centric web-pages using built-in Javascript and Ajax support. There are extensive chapters on testing, deployment, and scaling.

As with the previous editions of the book, the authors start with an extended tutorial that builds parts of an online store. And, of course, the application has been rewritten to show the best of Rails 2. «
