You want to write professional-grade application: Rails is a stack, a full open-source web framework, with integrated support for unit, functional and integration testing. But Rails is more than one set of best practices. Rails makes it both fun and easy to change a very cool web applications. Need support for Ajax, so that you are highly interactive web applications? Do you need an application with a REST-based interface (so they can interact with other tight applications with almost no effort on your part)? With this book you will learn how to use ActiveRecord to connect business objects and database tables. Just make your business objects and let Rails do the rest. 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. And, of course, the application has been rewritten to show the best of the V2 Rails.
