I'm not sure I understand. Does it also apply when the backref is
created implicitly, as follows:
class OT(DeclarativeBase):
[ snip ]
id_ot = Column(Integer, autoincrement=True, primary_key=True)
id_parent = Column(Integer,
ForeignKey('ot.id_ot', use_alter=True,
name='fk_ot_parent'))
OT.parent = relation(OT, remote_side=[OT.id_ot],
backref=backref('children'))

Ok, thank you.
