Legacy Single Table Inheritance - Specify Discriminator?

rubyonrails-talk

I have a legacy database that was designed to work with Hibernate. I have the following class hierachry:

class Status < ActiveRecord::Base class ItemStatus < Status   set_inheritance_column :item_type class MediaItemStatus < Status   set_inheritance_column :item_type

My issue is that the discriminator used in Hibernate was the string literal "MEDIA" for a MediaItemStatus and "ITEM" for an ItemStatus. I'm new to rails and I'm not finding a way to specify what AR should expect for actual discriminator values. Is this possible in Rails 2.3?

You could try overriding Status.compute_type
