I want to specify the following one-to-one relationship where an "Event" has one "FeeStructure". Essentially: class Event < ActiveRecord::Base has_one :fee_structure end class FeeStructure < ActiveRecord::Base belongs_to :event end The issue though is that FeeStructure is polymorphic. For example, I have FeeStructureTypeA and FeeStructureTypeB (they share common characteristics but they have different representation). It seems to me that want I'd need to do is the following: class Event < ActiveRecord::Base has_one :fee_structure :polymorphic => true end class FeeStructureTypeA < ActiveRecord::Base belongs_to :event, :as => fee_structure end class FeeStructureTypeB < ActiveRecord::Base belongs_to :event, :as => fee_structure end However this does not seem to be supported. Option ":polymorphic" appears to be supported only on "belongs_to". Looks like the only way I could make this work is if I would reverse the relationship. But that does not really make sense since "Event" is the parent in that relationship. Am I missing something here to make this work? Thanks, P.
