I'm having a problem extending ActiveRecord with custom validations
based on the "Write Custom Validations" recipe from Advanced Rails
Recipes. As far as I can tell, I've followed the instructions exactly
but for some reason this isn't working and it's driving me crazy.
I've tried making the methods in the custom validations module class
methods (self.validates...) as well as the way they are below (which
is the way they are in the instructions).
Any suggestions?
Thanks!
Gavin
