yes. and it actually supports mutliple table inheritance
single inheritance
db.define_table('player',db.Field('name'))
db.define_table('footballer',db.player,db.Field('club'))
db.define_table('cricketer',db.player,db.Field
('batting_average','integer'))
db.define_table('bowler',db.cricketer,db.Field
('bowling_average','integer'))
multiple inheritance
db.define_table('married',db.Field('companion_name'))
db.define_table('married_bowler',db.bowler,db.married)
too bad this is not yet documented anywhere. Perhaps you could help us
by writing somehting about it.
