mysql数据表自动导为python sqlalchemy可操作对象

1、pip install sqlacodegen

      pip install pymysql

     在/usr/lib/python/site-packages/sqlacodegen/main.py中添加：

          import pymysql

         pymysql.install_as_MySQLdb()

2、创建review_models.sh文件，在文件中添加：

      #!/usr/bin/env bash
      sqlacodegen --noviews --noconstraints --outfile=models.py mysql://iips:[email protected]:3306/iips

3、执行上面shell文件，将在当前目录下输出models.py，数据库iips中的表结构将转换成为sqlalchemy可操作的类对象，如下：

# coding: utf-8
from sqlalchemy import Column, DateTime, Integer, String
from sqlalchemy.ext.declarative import declarative_base


Base = declarative_base()
metadata = Base.metadata


class TBuilding(Base):
    __tablename__ = 't_building'

    id = Column(Integer, primary_key=True)
    building_code = Column(String(20), nullable=False, unique=True)
    land_code = Column(String(20), nullable=False, index=True)
    building_name = Column(String(40))
    building_area = Column(Integer)
    rent_area = Column(Integer)
    one_floor_area = Column(Integer, nullable=False)
    total_floors = Column(Integer, nullable=False)
    floor_hight = Column(Integer, nullable=False)
    loadbearing = Column(Integer, nullable=False)
    status = Column(Integer, nullable=False)
    structure = Column(String(40))
