Read the complete chapter
Rails is a fantastic tool for web application development, but its Ajax-driven interfaces stop short of the richness you gain with a tool like Adobe Flex. Simply put, Flex is the most productive way to build the UI of rich Internet applications (RIAs), and Rails is the most productive way to rapidly build a database-backed CRUD application. Together, they're an amazing combination.
Peter Armstrong's recent book "Flexible Rails: Flex 3 on Rails 2" is a book about how to use Ruby on Rails and Adobe Flex to build next generation RIAs. The book takes you to the leading edge of RIA development, presenting examples in Flex 3 and Rails 2.
The excerpted chapter, "Chapter 11: Refactoring to RubyAMF", is about refactoring the example developed over the course of the book to using RubyAMF. In this chapter, you will start by installing RubyAMF and doing a quick "hello world" test. You will then refactor the tasks, projects, locations, and note used in the application to be sent between Flex and Rails via RemoteObject and RubyAMF to Rails, instead of using HTTPService and XML.
Flexible Rails is not an exhaustive Ruby on Rails tutorial, nor a Flex reference manual. Instead, it's an extensive tutorial, developed iteratively, how to build an RIA using Flex and Rails together. You learn both the specific techniques you need to use Flex and Rails together as well as the development practices that make the combination especially powerful.
Flexible Rails is for both Rails developers who are interested in Flex, and Flex developers who are interested in Rails. For a Rails developer, Flex allows for more dynamic and engaging user interfaces than are possible with Ajax. For a Flex developer, Rails provides a way to rapidly build the ORM and services layer of the application.
