描述

Python版超市管理系统源代码，基于django+mysql安装步骤

1、在mysql中创建名为demo_django_supermarket的数据库，修改config/setting.py中数据库用户及密码

CREATE DATABASE demo_django_supermarket DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

2、pip install -r requirements

3、初始化数据库：manage.py migrate

4、设置一个超级管理员 admin (admin@123456)

manage.py loaddata fixtures/root_manager.yaml

5、启动服务

manage.py runserver localhost:8001
