Flask-SQLAlchemy 一对多数据库关系怎样存数据呢？

Question

class Person(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50))
    addresses = db.relationship('Address', backref='person',
                                lazy='dynamic')

class Address(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(50))
    person_id = db.Column(db.Integer, db.ForeignKey('person.id'))

小弟初学，请高人指点怎样用上面的模型存储数据呢，我去存储总是出错，非常感谢！

Answer 1

其实挺简单的
我一般的操作就是

person = Person.query.get(1)
address = Address(email=xxxx, person=person)
db.session.add(address)
db.session.commit()

ok!
