What exactly is "not working" here? Polymorphic associations are designed to store the class that's needed to retrieve the associated record - storing the STI subclass instead of the base would mean that the STI type was stored in *two* locations (both in the 'type' field on the record, and in 'item_type' on the associated Entity record) which is generally regarded as *bad*. Note that base-class finds still return objects of subclasses (this isn't C++ :) ): Name.find(some_team_id) # => a Team object --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
