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))

python 从数据库表生成model

 

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
