I have a single table inheritance model for some classes Payment < ActiveRecord::Base CreditCardPayment < Payment ECheckPayment < Payment ManualPayment < Payment they all get persisted to the payments table I'm getting an error: 'uninitialized constant Payment' when trying to create a new instance of any of these classes. At one point in my process I store the payment in a session variable, but I've it seems random as to when this happens: before or after that gets set. I even tried explicitly requiring the payment class in the sub classes, and still get the error. I'm using Webrick on ruby 1.8.3 installed on cygwin on a Windows XP machine. Any ideas what's going on? As I'm sure we all are, I'm under a time crunch, and this is an unexpected error. Please help!

That could be a source of problems: the Rails site specifically recommends against 1.8.3. I'd ditch cygwin ruby and use the one-click installer if I were you, just to get rid of the question mark. It's working fine for me.
