Sorry, I meant the section on conditions on a belongs_to:
4.1.3 Scopes for belongs_to
There may be times when you wish to customize the query used by belongs_to.
Such customizations can be achieved via a scope block. For example:
class Order < ActiveRecord::Base
belongs_to :customer, -> { where active: true },
dependent: :destroy
end
Still, I think my bigger problem is operating with Hobo outside of the
warm blanket of Rails.
