I just remembered the second part of my last question...
I have a superclass, Resource, which has two subclasses, TeachingObject and
LearningObject. All the records that are saved are one of the subclasses.
However, i'd like to be able to do a ferret search on Resource and get both
kinds of subclass, like when i do Resource.find(), which returns both kinds.
I'm having problems with the index though: TeachingObject and
LearningObject both have :store_class_name => true, and they have their own
indexes. When i try to build the index for Resource, it crashes with the
following trace, whether i have :store_class_name => true set for Resource
or not. Any ideas, anyone?
thanks, max
