Hello. I have Category model:
class Category(Base): __tablename__ = 'categories' id = Column(Integer, primary_key=True) parent_id = Column(Integer, ForeignKey('categories.id')) name = Column(Unicode(255), nullable=False) description = Column(UnicodeText) position = Column(Integer) children = relationship('Category', backref=backref('parent', remote_side=[id]), lazy='joined', join_depth=1, order_by='Category.position') But I can't access it's 'parent' backref (I want to use it in order_by). Why? >>> from whs.models import Category >>> Category.parent Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: type object 'Category' has no attribute 'parent' -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
