Ruby on Rails 2.0 released for Web apps

Key to this release is its reliance on REST Web services instead of SOAP Web services.Security enhancements also are featured. Available for download at the Ruby on Rails Web site, the framework leverages the Ruby programming language.

"The big thing we've been pushing in Rails 2.0 is the whole notion of REST and the whole notion of building REST-ful applications," as opposed to using SOAP, Hansson said.

"Rails used to ship with a library that did SOAP Web services. We've yanked that out and put in a bunch of things instead focused on doing REST Web services," he said.

REST is favored over SOAP now because those in the agile development camp feel it has become too complex, with its many WS-* standards to follow, said Hansson. Spoken as "WS star," Hansson instead denigrated the WS-* specifications by referring to them as "WS-Death Star."

Featuring specifications such as WS-Security, WS-* has been championed by companies such as Microsoft Corp. "[These standards] don't really do anything in a simple way, to put it mildly," said Hansson.

"We feel that [SOAP is] overly complicated. It's been taken over by the enterprise people, and when that happens, usually nothing good comes of it," Hansson said.

REST, meanwhile, has been built on the principles of the Web such as HTTP and straight XML, he said.

In the security space, Rails 2.0 makes it easier to protect against phishing, with provisions to guard against cross-site request forgery (CRSF) intrusions. Safeguards against cross-site forgery (XSF) attacks are included as well.

"We tried to make it really easy for people to deal with both of the scenarios," said Hansson.

Also featured in Rails 2.0 is improved testing support and backing for Atom feeds. "We're making it really easy for applications to emit feeds," which is critical to application updates, Hansson said.

Another new feature in Version 2.0 is a framework called ActiveResource, which encapsulates Web services and makes them as easy to use as databases, Hansson said. This is similar to the ActiveRecord feature for encapsulating database calls in Rails, he said.

While Hansson was the original creator of Ruby on Rails, the Dane stressed that he is no longer the only cook in the kitchen. "I'm only one out of hundreds of people who work on the framework," he said. Hansson is currently a partner at Chicago-based software development firm 37signals LLC.

Hansson previously stressed the REST bent of Ruby on Rail 2.0 during the RailsConf 2007 event in Portland this past May.
