Python数据库反向生成Model最优方案示例

# 反向生成Model
# 进入到项目根目录，输入下面的命令
# 其中
# student：映射数据库的student数据表
# 写入到index App 下的models.py文件内
python3 manage.py inspectdb student > index/models.py

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
engine = create_engine('mysql+pymysql://{}:{}@{}:{}/{}'.format(user, password, host, port, database), echo = True)
session = sessionmaker(bind=self.engine)()
...

# 安装依赖
pip3 install sqlacodegen

    """
    生成orm数据表

    exec_cmd(
        'sqlacodegen --tables {} --outfile {} mysql+pymysql://{}:{}@{}:{}/{}?charset=utf8'.format(
            table_name, output, username, pwd, db_ip, port, db_name))
