Sorry about the fuzz, after some more searching and experimenting, I
came up with the following which seems to work fine:
class Person(SQLObject):
name = StringCol(notNone=True)
father = ForeignKey('Person', default=None)
mother = ForeignKey('Person', default=None)
p1 = Person(name='John')
print p1, p1.father, p1.mother
p2 = Person(name='Jane')
print p2, p2.father, p2.mother
p3 = Person(name='Jeff', father=p1, mother=p2)
print p3, p3.father, p3.mother
Cheers,
Timo
