(How?) Is it possible to use validates_uniqueness_of with a scope that is a belongs_to association?
This is what I would like to do: class Lot < ActiveRecord::Base belongs_to :part, :include => true validates_uniqueness_of :identifier, :scope => :part end ...but (not surprisingly) when I run my unit test, I get: ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: lots.part Basically, I want to ensure that identifiers are unique for a given part. I think I'm going to have to write my own validation here, but I thought I would ask the question first. --wpd --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
