Error with uniqueness validator in rails

I am having a problem with my validation for a model. I want to ensure that for a particular Website that each Inventory name will remain unique.

When I add this to my model:

validates :name, :uniqueness => { :scope => :website }

I get this error:

TypeError - Cannot visit Account::Website:

The relationship is setup like this:

class Inventory < ActiveRecord::Base
  belongs_to :website, :class_name => 'Account::Website'

I have no idea but using this instead:

validates :name, :uniqueness => { :scope => :website_id }

Fixes it.

Anyone able to share why?
