python flask sqlalchemy 数据库mysql操作

第一步app.py：

# coding=utf-8
import urllib
from flask import Flask
from werkzeug.routing import BaseConverter
from flask.ext.sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['DEBUG'] = True
app.config['SQLALCHEMY_DATABASE_URI']="mysql://root:[email protected]:3306/pytest"

db = SQLAlchemy(app)


@app.route('/')
def hello_world():
    return 'Hello World!'


if __name__ == '__main__':
    app.debug = True
    app.run(host='0.0.0.0',port=9000)

第二步models.py:

import MySQLdb
from pytest import db

class Users(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String)
    password = db.Column(db.String)

    def __init__(self, id, name, password):
        self.id = id
        self.name = name
        self.password = password

第三步manager.py:

# encoding=utf-8
from flask_script import Manager
from pytest import app,db
from models import Users

manager = Manager(app)

@manager.command
def save():
    user = Users(4,'paul','12345678')
    db.session.add(user)
    db.session.commit()

@manager.command
def query_all():
    users = Users.query.all()
    for u in users:
        print u


if __name__=='__main__':
    manager.run()

完成！
