苍穹外卖-day04 0.项目实战 完成套餐管理模块所有业务功能,包括:
新增套餐
套餐分页查询
删除套餐
修改套餐
起售停售套餐
要求:
根据产品原型进行需求分析,分析出业务规则
设计接口
梳理表之间的关系(分类表、菜品表、套餐表、口味表、套餐菜品关系表)
根据接口设计进行代码实现
分别通过swagger接口文档和前后端联调进行功能测试
1. 新增套餐 1.1 需求分析和设计 产品原型:
业务规则:
套餐名称唯一
套餐必须属于某个分类
套餐必须包含菜品
名称、分类、价格、图片为必填项
添加菜品窗口需要根据分类类型来展示菜品
新增的套餐默认为停售状态
接口设计(共涉及到4个接口):
根据类型查询分类(已完成)
根据分类id查询菜品
图片上传(已完成)
新增套餐
数据库设计:
setmeal表为套餐表,用于存储套餐的信息。具体表结构如下:
字段名
数据类型
说明
备注
id
bigint
主键
自增
name
varchar(32)
套餐名称
唯一
category_id
bigint
分类id
逻辑外键
price
decimal(10,2)
