2. Mapping

source imooc/bin/activate

cd /home/www/order/

flask-sqlacodegen 'mysql://root:[email protected]/food_db' --tables notice --outfile "common/models/member/Notice.py"  --flask

In the generated object file

order/common/models/member/Notice.py

Put

from flask_sqlalchemy import SQLAlchemy


db = SQLAlchemy()

Change to:

from application import db, app

The complete file is as follows

# coding: utf-8
from sqlalchemy import Column, DateTime, Integer, String
from sqlalchemy.schema import FetchedValue
from application import db, app


class Notice(db.Model):
    __tablename__ = 'notice'

    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False, server_default=db.FetchedValue())
    summary = db.Column(db.String(10000), nullable=False, server_default=db.FetchedValue())
    status = db.Column(db.Integer, nullable=False, server_default=db.FetchedValue())
    view_count = 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())
