一、关于数据库表的设计
-
1、商品属性表
比如一个衣服有颜色、尺码、款式这个叫属性表
-- ------------------------ -- 商品属性表 -- ------------------------ DROP TABLE IF EXISTS `attribute`; CREATE TABLE `attribute` ( `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT COMMENT '主键id', `name` varchar(50) not null COMMENT '属性名', `status` tinyint(4) DEFAULT 0 COMMENT '状态,0表示正常,1表示禁用', `remark` varchar(100) default null comment '备注', `created_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) COMMENT '创建时间', `updated_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6) COMMENT '更新时间', `deleted_at` timestamp(6) NULL DEFAULT NULL COMMENT '软删除时间', UNIQUE KEY `UK_name_deleted_at` (`name`,`deleted_at`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin COMMENT = "商品属性表"; -
2、商品属性值表
上面说的颜色，可能是红色、黄色、绿色，尺码可能是S、M、L
-- ------------------------ -- 商品属性值表 -- ------------------------ DROP TABLE IF EXISTS `attribute_value`; CREATE TABLE `attribute_value` ( `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT COMMENT '主键id', `attribute_id` int(11) not null comment '关联到attribute表主键id', `name` varchar(50) not null COMMENT '属性值', `status` tinyint(4) DEFAULT 0 COMMENT '状态,0表示正常,1表示禁用', `remark` varchar(100) default null comment '备注', `created_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) COMMENT '创建时间', `updated_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6) COMMENT '更新时间', `deleted_at` timestamp(6) NULL DEFAULT NULL COMMENT '软删除时间', UNIQUE KEY `UK_attribute_id_name_deleted_at` (`attribute_id`,`name`,`deleted_at`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin COMMENT = "商品属性值表"; -
3、
spu表,或者直接叫商品表也可以的spu表比如我们说的苹果手机、华为手机、戴尔笔记本这样的叫spu-- ------------------------ -- 商品spu表 -- ------------------------ DROP TABLE IF EXISTS `spu`; CREATE TABLE `spu` ( `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT COMMENT '主键id', `name` varchar(50) not null COMMENT '商品名称', `keyword` varchar(50) not null COMMENT '关键词', `introduction` varchar(100) not null COMMENT '简介', `category_id` int(11) not null COMMENT '关联到category表主键id', `brand_id` int(11) default null comment '关联到brand表主键id', `pic_url` varchar(200) default null comment '封面图', `video_url` varchar(200) default null comment '视频地址', `slider_pic_urls` varchar(500) default null COMMENT '商品轮播图地址', `unit` int(11) default null comment '单位,关联到dict表主键id', `spec_type` tinyint(4) default 0 comment '单双规格,0表示单规格,1表示多规格(sku)', `price` decimal(10,2) default '0.00' comment '商品单价', `market_price` decimal(10,2) default '0.00' comment '商品市场价', `discount_price` decimal(10,2) default '0.00' comment '商品折扣价', `vip_price` decimal(10,2) default '0.00' comment '商品vip价', `cost_price` decimal(10,2) default '0.00' comment '商品成本价', `stock` int(11) default 0 comment '库存(如果是多规格求和)', `sort` int(11) DEFAULT 1 COMMENT '排序', `status` tinyint(4) DEFAULT 0 COMMENT '状态,0表示正常,1表示禁用', `is_hot` tinyint(4) DEFAULT 0 COMMENT '是否热销,0表示不是,1表示是', `is_benefit` tinyint(4) DEFAULT 0 COMMENT '是否优惠推荐,0表示不是,1表示是', `is_best` tinyint(4) DEFAULT 0 COMMENT '是否精品,0表示不是,1表示是', `is_new` tinyint(4) DEFAULT 0 COMMENT '是否新品,0表示不是,1表示是', `is_good` tinyint(4) DEFAULT 0 COMMENT '是否优品推荐,0表示不是,1表示是', `give_integral` int(11) DEFAULT 0 COMMENT '赠送积分', `sales_count` int(11) DEFAULT 0 COMMENT '销量', `browse_count` int(11) DEFAULT 0 COMMENT '浏览数', `content` text NOT NULL COMMENT '商品详情', `attribute` varchar(1000) default null COMMENT '销售属性数组，JSON 格式', `remark` varchar(100) default null comment '备注', `created_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) COMMENT '创建时间', `updated_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6) COMMENT '更新时间', `deleted_at` timestamp(6) NULL DEFAULT NULL COMMENT '软删除时间', UNIQUE KEY `UK_name_deleted_at` (`name`,`deleted_at`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin COMMENT = "商品spu表"; -
4、
sku表上面说的苹果手机，可能是【黄色-128GB-大陆版】，【白色-256GB-港版】这样的叫
sku-- ------------------------ -- 商品sku表 -- ------------------------ DROP TABLE IF EXISTS `sku`; CREATE TABLE `sku` ( `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT COMMENT '主键id', `spu_id` int(11) NOT NULL comment '关联到spu主键id', `attribute_value` varchar(200) default null comment '销售属性值:用英文,拼接', `price` decimal(10,2) default '0.00' comment '商品单价', `market_price` decimal(10,2) default '0.00' comment '商品市场价', `discount_price` decimal(10,2) default '0.00' comment '商品折扣价', `vip_price` decimal(10,2) default '0.00' comment '商品vip价', `cost_price` decimal(10,2) default '0.00' comment '商品成本价', `bar_code` varchar(64) DEFAULT NULL COMMENT 'SKU 的条形码', `pic_url` varchar(200) NOT NULL COMMENT '图片地址', `stock` int DEFAULT NULL COMMENT '库存', `weight` double DEFAULT NULL COMMENT '商品重量，单位：kg 千克', `volume` double DEFAULT NULL COMMENT '商品体积，单位：m^3 平米', `sales_count` int DEFAULT NULL COMMENT '商品销量', `created_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) COMMENT '创建时间', `updated_at` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6) COMMENT '更新时间', `deleted_at` timestamp(6) NULL DEFAULT NULL COMMENT '软删除时间' ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin COMMENT = "商品sku表";
二、前端选择销售属性
-
1、最后效果图
-
2、上面的数据提前手动插入到数据库中的
- 3、后端提供一个接口先查询全部的商品属性，在根据商品属性的
id去查询商品属性值，这块可以自己见代码
三、选择商品属性生成SKU
- 1、效果展示
-
2、由销售属性来生成下面的表格的方法
const checkPropertyList = ref([]); /** * 生成sku数据 * @param {*} skuAttribute 选中的商品属性 */ const generateSku = (skuAttribute) => { console.log(JSON.stringify(skuAttribute)); const attrValue = []; // 获取选中的属性 const checkList = []; for (const item of skuAttribute) { attrValue.push(item.attributeItem.filter((it) => item.checkList.includes(it.id))); checkList.push(item.id); // 选中的主键id } checkPropertyList.value = checkList; console.log(attrValue, '???'); if (attrValue.length == 0) { tableData.value = []; return; } // 处理添加一个属性的时候表格置空 if (!attrValue[attrValue.length - 1].length) { return; } // 循环组成sku数据 const skuList = attrValue .reduce((pre, cur) => { let res = []; for (const item of pre) { for (const it of cur) { let t = item.name + ',' + it.name; res.push({ name: t, url: item.url || it.url || '', }); } } return res; }) .map((it) => { const oldData = afterSku.value.find((item) => item.name == it.name); return { ...it, id: oldData ? oldData.id : '', price: oldData ? oldData.price : '', // 单价 stock: oldData ? oldData.stock : '', // 库存 }; }); tableData.value = skuList; }; -
3、在什么时候调用上面这个方法呢?,直接监听销售属性的变化就可以
watch( () => skuAttributes.value, (newValue) => { generateSku(cloneDeep(newValue)); }, { deep: true, } ); // 监听sku表格的变化,并将当前sku进行备份 const afterSku = ref([]); watch( () => tableData.value, (value) => { afterSku.value = cloneDeep(value); }, { deep: true } ); -
4、点击按钮提交数据给后端
const submitHandler = async () => { ElMessage.success('请查看浏览器控制台'); console.log('销售属性:', JSON.stringify(skuAttributes.value)); console.log('表格数据:', JSON.stringify(tableData.value)); const postData = { name: '苹果13', keyword: '苹果手机', introduction: 'laboris sint in', categoryId: 10, brandId: 50, picUrl: 'http://dummyimage.com/400x400', videoUrl: 'http://voanozyj.vg/suuadzgv', sliderPicUrls: 'http://dummyimage.com/400x400', unit: 25, specType: 79, price: 90, marketPrice: 11, discountPrice: 82, vipPrice: 32, costPrice: 87, stock: 19, sort: 33, isHot: 0, isBenefit: 0, isBest: 0, isNew: 0, isGood: 0, giveIntegral: 43, content: '手机详情', remark: 'magna eu laboris', // 过滤掉没有选择的sku属性 attribute: JSON.stringify(skuAttributes.value), skuList: tableData.value.map((item) => { return { ...item, attributeValue: item.name, barCode: item.name, discountPrice: item.price, costPrice: item.price, picUrl: 'http://dummyimage.com/400x400', vipPrice: item.price, volume: 85, marketPrice: 26, weight: 50, }; }), }; console.log(JSON.stringify(postData), '提交数据'); const data = await SkuService.createSpuApi(postData); console.log(data); }; -
5、完整代码如下

四、前端实现sku选择
