how do I create a virtual jquery filetree?

I would like to create something like this using ruby on rails.

Im not tied to jquery 开发者_运维知识库but it seems like this his what I want: http://labs.abeautifulsite.net/projects/js/jquery/fileTree/demo/

The issue is I want to build the tree not based on a file system, but based on ruby code which pulls info from various models. In other words, my files are stored in the database under various models and I want to query them and decide to build how to build the file tree.

thanks Joel

The FileTree plugin is independent from server-side scripts and offers the possibility to create custom connectors to feed it with data:

this should be very easy to connect with a simple Ruby script.
