Hello!
How can I cache query like this:
session.query(Person).get(51)
where 51 is id of Man
I can't access attribute age of Man without SELECT.
Models:
class Person(Base):
__tablename__ = 'person'
id = Column(Integer, primary_key=True)
name = Column(String(100), nullable=False)
type = Column(String(50))
__mapper_args__ = {
'polymorphic_identity': 'object',
'polymorphic_on': type
}
class Man(Person):
__tablename__ = 'man'
id = Column(Integer, ForeignKey('person.id'), primary_key=True)
age = Column(String(100), nullable=False)
__mapper_args__ = {'polymorphic_identity': 'man'}
