首先安装flask-sqlalchemy

db = SQLAlchemy(app)

一 Mmeber、User模型类的创建

# coding: utf-8
from app import db, app

class Member(db.Model):
    __tablename__ = 'member'

    id = db.Column(db.Integer, primary_key=True)
    membername = db.Column(db.String(100), unique=True, index=True, info='会员名')
    mobile = db.Column(db.String(11), server_default=db.FetchedValue(), info='会员手机号码')
    sex = db.Column(db.Integer, nullable=False, server_default=db.FetchedValue(), info='性别 1:男 2:女')
    avatar = db.Column(db.String(200), nullable=True, server_default=db.FetchedValue(), info='会员头像')
    salt = db.Column(db.String(32), nullable=False, server_default=db.FetchedValue(), info='随机salt')
    reg_ip = db.Column(db.String(100), nullable=False, server_default=db.FetchedValue(), info='注册ip')
    status = db.Column(db.Integer, nullable=False, server_default=db.FetchedValue(), info='状态 1:有效 0:无效')
    updated_time = db.Column(db.DateTime, nullable=False, server_default=db.FetchedValue(), info='最后一次更新时间')
    created_time = db.Column(db.DateTime, nullable=False, server_default=db.FetchedValue(), info='插入时间')


    @property
    def status_desc(self):
        return app.config['STATUS_MAPPING'][str(self.status)]

    @property
    def sex_desc(self):
        sex_mapping = {
            "0":"未知",
            "1":"男",
            "2":"女"
        }
        return sex_mapping[str(self.sex)]

    #status 统一返回sex表格的字段,  虚拟的好处是  直接可以在index.html中直接使用。  虚拟字段不可以查询




# coding: utf-8
from app import db

class User(db.Model):
    __tablename__ = 'user'
    uid = db.Column(db.BigInteger, primary_key=True)
    nickname = db.Column(db.String(100), nullable=False, server_default=db.FetchedValue())
    mobile = db.Column(db.String(20), nullable=False, server_default=db.FetchedValue())
    email = db.Column(db.String(100), nullable=False, server_default=db.FetchedValue())
    sex = db.Column(db.Integer, nullable=False, server_default=db.FetchedValue())
    avatar = db.Column(db.String(64), nullable=False, server_default=db.FetchedValue())
    login_name = db.Column(db.String(20), nullable=False, unique=True, server_default=db.FetchedValue())
    login_pwd = db.Column(db.String(32), nullable=False, server_default=db.FetchedValue())
    login_salt = db.Column(db.String(32), nullable=False, server_default=db.FetchedValue())
    status = db.Column(db.Integer, nullable=False, server_default=db.FetchedValue())
    updated_time = db.Column(db.DateTime, nullable=False, server_default=db.FetchedValue())
    created_time = db.Column(db.DateTime, nullable=False, server_default=db.FetchedValue())

二 app.py中导入User,Member模型类

from common.models.member import Member
from common.models.User import User

三: 在终端代码中给数据库创建对应的Member表格  和User表格

首先进入flask shell,然后使用创建代码

db.create_all()
