Picasa Browser with Ruby on Rails

I would like to show small example how to use AIR application and Ruby on Rails for backend. PicasaBrowser is very simple application with 2 http requests to server:

1. to obtain list of public albums for specified gallery


2. to get all photos from selected album.


In the RoR application I have used REXML library to parse rss feed. I know, my ruby code is not perfect and is not in ruby style (yet :)), so I would like you to correct my code.

Air app source code. ROR source code.

On Flex on Rails blog you could find few more examples of AIR and Rails applications.
