（阶段三：整合）面向用户面向商户，场景之：shop-拓冰建站

1. 明确边界：cms配置的 PageInstance.sections 数组只用来配置

【默认内容 + 主题颜色（未来开放）】

[section_display]props:// 商户定义“这个模块默认展示哪些分类”category_ids_default: ['software', 'education'], sort_tag_default: 'latest' priceRangeBreakpoints: [20, 40, 80] pagination: { pageSize: 12 },CTA: {title: "现在开始",buttonText: "立即购买",description: "xxxxx"position: 6}
}[section_detail]
------ 更新设计：“持久化时扁平，运行时结构化”-------props: {category_ids_default: ['software', 'education'],sort_tag_default: 'latest',price_range_breakpoints: [20, 40, 80],page_size: 12,CTA_title: '立即购买',CTA_buttonText: '现在开始',CTA_description: 'xxxxx',CTA_position: 6
}

渲染前将扁平字段还原成对象：

const CTA = {title: props.CTA_title,description: props.CTA_description,buttonText: props.CTA_buttonText,position: props.CTA_position,
}

数据型，如category，依然是放在数据库的table里面

2. 细说price range设计

CMS部分

1. 💡 商户只输入数字数组（比如在 UI 上输入 tag：`20`、`40`、`80`）：

type PriceBreakpoints = number[] // e.g. [20, 40, 80]

SectionInstance.props存储

props: {priceRangeBreakpoints: [20, 40, 80]
}

前端渲染部分：根据 priceRangeBreakpoints 转化成标签

2. ✅ 平台自动转成区间列表：

type PriceRangeOption = {label: stringmin?: numbermax?: number
}function generatePriceRanges(breakpoints: number[]): PriceRangeOption[] {const sorted = [...breakpoints].sort((a, b) => a - b)const ranges: PriceRangeOption[] = []if (sorted.length === 0) return []// Less than first
  ranges.push({max: sorted[0],label: `Less than $${sorted[0]}`})for (let i = 0; i < sorted.length - 1; i++) {ranges.push({min: sorted[i],max: sorted[i + 1],label: `$${sorted[i]} - $${sorted[i + 1]}`})}// More than last
  ranges.push({min: sorted[sorted.length - 1],label: `More than $${sorted[sorted.length - 1]}`})return ranges
}

sql查询部分：

标签为：

[{ max: 20, label: "Less than $20" },{ min: 20, max: 40, label: "$20 - $40" },{ min: 40, max: 80, label: "$40 - $80" },{ min: 80, label: "More than $80" }
]

当用户点击某个 price tag，你将这个 { min?, max? } 作为 query param 发给后端：

GET /api/products?price_min=20&price_max=40

后端查询：

function getProducts({ price_min, price_max }) {const conditions = []if (price_min !== undefined) {conditions.push(`price >= ${price_min}`)}if (price_max !== undefined) {conditions.push(`price < ${price_max}`)}const whereClause = conditions.length > 0 ? `WHERE ${conditions.join(' AND ')}` : ''const sql = `SELECT * FROM products${whereClause}ORDER BY price ASCLIMIT 20 OFFSET 0`return db.query(sql)
}
