As I've mentioned serveral times lately I'm currently working on a Rails application.  Overall, I've really enjoyed the experience and I'm glad that I took the plunge into unknown territory.  For the most part I've been creating everything within my Rails application as resources.  For those who don't know, using resources within Rails is how cool people build Rails apps these days.  Creating a Rails app as a set of resources makes it so your app automagically has a set of RESTful services that can be consumed by the likes of ActiveResource. Up until know I've had things setup pretty simply, and as such have only had standalone resources.  Tonight I needed to add a nested resources and found this post on the topic very helpful.
