1.操作mysql代码; import MySQLdb def get_conn(): host = "127.0.0.1" port = 3306 db = "python" user = "root" password = "123456" conn = MySQLdb.connect(host=host,user=user,password=password,db=db,port=port,charset="utf8") return conn class User(object): def __init__(self,user_id,user_name): self.user_id = user_id self.user_name = user_name def save(self): conn = get_conn() cursor = conn.cursor() sql = "insert into user (user_id,user_name) VALUES (%s,%s)" cursor.execute(sql.user_id,self.user_name) conn.commit() cursor.close() conn.close() @staticmethod def query_all(): conn = get_conn() cursor = conn.crusor() sql = "select * from user" cursor.execute(sql) rows = cursor.fetchall() users= [] for i in rows: user = User(r[0], r[i]) users.append(user) conn.commit() cursor.close() conn.close() return users def __str__(self): return "id:{}-name:{}".format(self.user_id,self.user_name) 2.调用方法; #endcoding=utf-8 from flask_script import Manager from app import app from models import User manager = Manager(app) @manager.command def save(): user = User(1,'breaklinux_project') user.save() @manager.command def query_all(): users = User.query_all() for u in users: print u if __name__ == '__main__': manager.run()标签：ldb [] etc manager __name__ root models 127.0.0.1 mit
