Reaching through a belongs_to for acts_as_list scope?
I''m running into a situation where I''d like to provide the list scope
for an acts_as_list model from one step removed. In minimalistic form
(with several other associations removed from each level).
class MainEntity < AcrtiveRecord::Base
has_many :containers
end
class Container < ActiveRecord::Base
has_many :elements

end

belong_to :containers
acts_as_list :scope=> ??? # it wants to be container.main_entity_id
end
