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:iips@192.168.1.200:3306/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))
