combining STI + polymorphism + rich self HABTM : how to ?
Hi all,
I need to model simple typed polymorphic relations:
''John'' [''works_for''] ''Bill''
''John'' [''speaks_for''] ''Microsoft''
''Microsoft'' [''hold_shares_of''] ''Apple''
I''m having a hard time combining :
- S.T.I. : ''people'' and ''companies'' are different kind of
''entities'' that can relate to other ''entities''
- polymorphism self-ref HA...
