sudo apt-get install Flask-SQLAlchemy

# 安装后可直接在py中使用 import flask from flask.ext.sqlalchemy import SQLAlchemy app = flask.Flask(__name__) # - Settings里配置了SqlAlchemy的数据库地址 # sqlite ex: "sqlite:///dbname.db" app.config.from_object("Settings") db = SQLAlchemy(app) db.init_app(app) # - create_all() 调用时将会创建所有继承db.Model的模版 # Model ex: 见 Class AdminInfo db.create_all() class AdminInfo(db.Model):   id = db.Column(db.Integer, primary_key = True)   name = db.Column(db.String(16))   password = db.Column(db.String(32))   kidname = db.Column(db.String(16))   diy_show = db.Column(db.Text)   def __init__(self, name, password, kidname, diy_show):     self.name = name     self.password = password     self.kidname = kidname     self.diy_show = diy_show   def __repr__(self):     return "<name: %s  pw: %s>"%(self.name, '*'*len(self.password))

# 对AdminInfo进行操作 ai = AdminInfo("gaoyiping", "gaoyiping", u"我叫高一平", u"大家好，我叫高一平，你叫什么？我们交个朋友啊。") # 这样就已经实例了一个SQL Data # 对db进行插入 db.session.add(ai) # 对db commit db.session.commit() # 如果进行查询 AdminInfo.query.all() # >>> [<name: gaoyiping  pw: *********>, ] AdminInfo.query.get(1) # 查询刚插入的第一条记录 # >>> <name: gaoyiping  pw: *********> AdminInfo.query.filter_by(name = "gaoyiping") # >>> <name: gaoyiping  pw: *********>
