Ruby on Rails, a popular Web development framework based on the Ruby programming language, makes it easy to access your database, but it does not always do so efficiently. Learn more about common performance problems with Rails, including N+1 query, and discover how you can fix them.

Part-3 introduces the RDT and RadRails Eclipse plug-ins and shows you how to get these plug-ins and start using them. You will learn how to use RadRails to do many common Ruby on Rails development tasks.

In Part-2 you'll see how easy it is to develop PHP applications using a different set of Eclipse plug-ins, collectively known as the PHP Development Toolkit (PDT).

Part-1 shows you how to use Eclipse to connect to a database, create tables, and create test data in our database. This three-part "Web development with Eclipse Europa" series shows you how to use Eclipse for Web development with Java technology, PHP, and Ruby. You'll see how the latest release of Eclipse -- Europa -- can be used to rapidly develop Java Web applications.

Programmmers who use the Ruby on Rails framework also mix Ruby in HTML templates similar to JSP and PHP. These templates, called RHTML files, are very useful for creating dynamic user interfaces, and this article will show you how to extend our Ruby support to include them.

The Ruby on Rails community embraces testing like the USA embraces American Idol. They watch their test case results roll by with great regularity. Ruby developers talk about testing; they blog about it; they even participate behind the scenes, not with cell phone votes but by contributing open source frameworks. Learn about the trade-offs of several Ruby on Rails testing strategies. This article walks you through the basic out-of-the-box testing techniques, and how those compare with the newer mocking frameworks.

With the introduction of the IBM_DB adapter and driver, Rails applications can now interact seamlessly with IBM data servers.

A new wave of extensions for Rails have been created thanks to an effective plug-in architecture that thousands of people have used to extend Rails. Many of these techniques are available to Java developers too, through aspect-oriented programming or bytecode enhancement. See how Ruby on Rails plug-ins work by looking at a popular plug-in called acts_as_state_machine. Its a great example of a good integration technique.
