如何创建一个简单的函数来更改sqlalchemy.orm中的值

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.orm.exc import NoResultFound
from sqlalchemy.orm import scoped_session
from sqlalchemy.ext.declarative import declarative_base

engine = create_engine('数据库连接字符串')

Session = sessionmaker(bind=engine)

session = Session()

Base = declarative_base()

class YourModel(Base):
    __tablename__ = 'your_table_name'
    id = Column(Integer, primary_key=True)
    column1 = Column(String)
    column2 = Column(Integer)
    # 定义其他列...

def update_value(session, model_id, new_value):
    try:
        obj = session.query(YourModel).filter_by(id=model_id).one()
        obj.column1 = new_value
        session.commit()
        return True
    except NoResultFound:
        return False

result = update_value(session, 1, 'new_value')
if result:
    print("值已成功更改")
else:
    print("未找到对应的记录")
