The declared_attr attributes are called by the metaclass for IceCream before

Hi, I'm trying to call the base class attributes from a declared_attr
definition.
Something like:
class Edible(Base):
__tablename__ = 'edible'
brand = Column(String(20), primary_key=True)
edible_type = Column(String(20), primary_key=True)
__mapper_args__ = {'polymorphic_on': edib
