Single Table Inheritance in Rails: Sample App Available

I'm using Rails STI on a project, so I extracted the basics and wrote
up some basics on single table inheritance and how it's used in Rails.

Two blog posts, first is here:
http://joemcglynn.wordpress.com/2009/12/11/rails-sti-part-1/

Second is here:
http://joemcglynn.wordpress.com/2009/12/12/rails-single-table-inheritance-part-2/

I put the sample code on my github repository:
http://github.com/canonical/Single-Table-Example

I plan to write one more segment on STI showing some more advanced
scenarios.

Cheers,
Joe

Part 3 of the Rails STI post is available now:
http://joemcglynn.wordpress.com/2009/12/16/rails-single-table-inheritance-part-iii/

The example source code for part 2 is on github:
http://github.com/canonical/Single-Table-Example

Cheers,
