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))

python 从数据库表生成model

找了很久才找到这个，我是新手...

现在已有建好的数据库，需要基于原有数据做数据分析的web应用，我选择python+Tornado ,由于不想写SQL语句，就想偷个懒

1、安装工具

1 ningjian@freegodly:~/code/py/django/logcloud$ sudo pip install sqlacodegen

2 Downloading/unpacking sqlacodegen

3   Downloading sqlacodegen-1.1.6-py2.py3-none-any.whl

4 Downloading/unpacking inflect>=0.2.0 (from sqlacodegen)

5   Downloading inflect-0.2.5-py2.py3-none-any.whl (58kB): 58kB downloaded

6 Requirement already satisfied (use --upgrade to upgrade): SQLAlchemy>=0.6.0 in /usr/local/lib/python2.7/dist-packages (from sqlacodegen)

7 Installing collected packages: sqlacodegen, inflect

8 Successfully installed sqlacodegen inflect

9 Cleaning up...

2、转换

ningjian@freegodly:~/code/py/django/logcloud$ sqlacodegen mssql+pymssql://name:password@ip/LogColudDB --outfile logcloude_model.py

ningjian@freegodly:~/code/py/django/logcloud$

3、查看，哈哈

ningjian@freegodly:~/code/py/django/logcloud$ cat logcloude_model.py
