I'm trying to do exactly what is described here:
http://www.sqlalchemy.org/docs/mappers.html#adjacency-list-relationships
But I'm using declarative. Here's what I have but it fails with the exception
below:
class Option(Base):
__tablename__ = 'options'
id_ = Column(Integer, primary_key=True)
parent_id = Column(Integer, ForeignKey('options.id_'))
parent = relationship('Option',
backref=backref('children', order_by=name,
remote_side=['options.c.id_']))
sqlalchemy.exc.ArgumentError: Relationship Option.children could not determine
any local/remote column pairs from remote side argument set
How do I make this work with declarative?
Thanks,
Michael
