Hello. I''m attempting to use STI for a class that contains a reference_id field. However, the class_name of the reference isn''t known in the base class because each subclass uses a different reference class_name. Basically, it looks like this: class Note < ActiveRecord::Base end class ProjectNote < Note has_one :reference, :class_name => ''Project'' end class ClientNote < Note has_one :reference, :class_name => ''Client'' end Then in test/fixtures/notes.yml, I have: client_note: reference: my_client project_note: reference: my_project This works fine (and I define helpers for the class to access their reference), but when it comes to fixtures, I''m stumped. When rails tries to load the fixtures, I get an error about an ''unknown column "reference" in "field list" for the "notes" table, and according to the SQL it''s trying to insert the name of the Client fixture into the "reference" field, instead of using the id in the "reference_id" field. I''m not 100% positive what I''m attempting to do is even possible, but I would appreciate whatever help / advice anyone can offer.
