我定义了一个 SqlAlchemy 模型

from sqlalchemy.dialects.postgresql import JSONB

class User(db.Model):
    __tablename__ = "user"
    id = db.Column(db.Integer, primary_key=True)
    nickname = db.Column(db.String(255), nullable=False)
    city = db.Column(db.String(255))
    contact_list = db.Column(JSONB)
    created_at = db.Column(db.DateTime, default=datetime.utcnow)

def add_user():
    user = User(nickname="Mike")
    user.contact_list = [{"name": "Sam", "phone": ["123456", "654321"]}, 
                         {"name": "John", "phone": ["159753"]},
                         {"name": "Joe", "phone": ["147889", "98741"]}]
    db.session.add(user)
    db.session.commit()

if __name__ == "__main__":
    add_user()

如何使用电话从我的contact_list 中检索姓名？例如，我有147889，我如何检索Joe？
