Is there any way for Torque to understand the relationship between specific columns and specific subclasses?
I studied the generated code from the schema below (simplified). It builds the class hierarchy correctly but the subclasses seem to be different in name only. Is there any way to specify in the schema which columns are relevant to which subclasses?
In this example, each of the columns in the last block should be unique to one the three subclasses: Person, Project, Organization. The generated code would let a Person object have an organization name. If Torque can't specify these relationships, how have people been restricting access to irrelevant attributes? Do you just override the accessors and throw exceptions in the body?
Thanks for any ideas,
