Playing with Ruby on Rails


I’ve started playing with Ruby on Rails. For simple CRUD interfaces, I’ve found it is very fast and easy. Here is a demo of multiple related selection boxes using Ajax. In the screen shot, Zip Code has been constrained by the previous selections for State, County, and Post Office. It works like you would expect, selecting a State constrains selections for County, Post Office, Zip Code, and selecting a County constrains Post Office, etc. I used Richard White’s excellent Ajax Scaffold for this demo. The data is from the 2000 Census.
