Hi Fred, Thanks for your timely response.
> what makes you think they aren't there ? I searched for them to no avail. Shouldn't they be in the Expense model (app\models\expense.rb); or Expense controller (app\controllers\expenses_controller.rb? I made a case-insensitive search for /vendor.nil\?/ in every application file whose name matched /e?rb/i to no avail. Could it be that adding relationships after the app & the database have been created doesn't work? Would I have better luck if I scrapped everything and recreated the app with the relationships defined? IMHO, that would substantially limit the usefulness of relationship macros.
