here is code:
Base = declarative_base()
class Page(Base):
__tablename__ = 'pages'
id = Column(Integer, primary_key=True)
parent_id = Column('parent_id', Integer, ForeignKey('pages.id'))
children = relation('Page', backref='parent')
I get error information：
sqlalchemy.exc.ArgumentError: Page.children and back-reference
Page.parent are both of the same direction <symbol 'ONETOMANY>. Did
you mean to set remote_side on the many-to-one side ?
when change the code
children = relation('Page', backref='parent')
to
childen = relation('Page')
It can work , but I can only get 'children' no 'parent' from a Page instant.
