将字典绑定到SQLAlchemy模型以进行更新

from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base

# 创建数据库连接
engine = create_engine('数据库连接字符串')

# 创建会话
Session = sessionmaker(bind=engine)
session = Session()

# 创建基类
Base = declarative_base()

# 定义模型类
class User(Base):
    __tablename__ = 'users'
    id = Column(Integer, primary_key=True)
    name = Column(String)
    age = Column(Integer)

# 创建字典对象
data = {'name': 'John', 'age': 25}

# 查询数据库中的记录
user = session.query(User).filter_by(id=1).first()

# 将字典绑定到模型实例
for key, value in data.items():
    setattr(user, key, value)

# 提交更新
session.commit()
