name: cc-field-mapping-safety
description: 当重构涉及字段映射(dataIndex、枚举映射、类型转换)时触发。防止字段名推测错误,确保字段映射的正确性。
---

# 字段映射安全规范

## 触发场景

- 重构表格列定义(dataIndex、columns)
- 重构枚举类型映射(typeMap、statusMap)
- 重构数据转换逻辑(render 函数、formatter)
- 类型定义中有多个相似字段(changedAt vs createdAt)

---

## 核心原则

**不要根据类型定义推测字段名,必须查看原始代码的实际使用**

---

## 检查清单

### 1. 字段名验证

- [ ] 查看原始代码的 dataIndex
- [ ] 查看后端 API 返回的实际字段名
- [ ] 优先使用必填字段,避免可选字段
- [ ] 注意字段名的细微差异(changedAt vs createdAt、changeType vs operationType)

### 2. 枚举映射验证

- [ ] 对照原始代码,逐个检查枚举值
- [ ] 确保映射完整(不遗漏任何枚举值)
- [ ] 检查枚举值的拼写(UPLOAD vs Upload)
- [ ] 检查枚举值的颜色、文本是否一致

### 3. 运行时测试

- [ ] TypeScript 类型检查通过(必要但不充分)
- [ ] 在实际环境中测试功能
- [ ] 检查是否显示 "Invalid Date"、"undefined"、空白
- [ ] 检查枚举值是否都有对应的映射

---

## 常见陷阱

### 陷阱 1: 类型定义有歧义

**场景**:类型定义中有多个相似字段

```typescript
interface InvoiceHistory {
  changedAt?: string  // 可选字段
  createdAt: string   // 必填字段
  changeType?: string // 错误字段
  operationType: string // 正确字段
}
```

**错误做法**:
```typescript
// ❌ 根据类型定义推测,选择了可选字段
dataIndex: 'changedAt'  // 可能为 undefined → Invalid Date
dataIndex: 'changeType' // 字段不存在 → 显示为空
```

**正确做法**:
```typescript
// ✅ 查看原始代码的实际使用
git show HEAD~1:src/components/InvoiceHistoryTab.tsx

// 原始代码使用 createdAt(必填)和 operationType(正确)
dataIndex: 'createdAt'
dataIndex: 'operationType'
```

### 陷阱 2: 枚举映射不完整

**场景**:重构时遗漏部分枚举值

**错误做法**:
```typescript
// ❌ 只保留了 3 个类型
typeMap: {
  CREATE: { text: '创建', color: 'green' },
  UPDATE: { text: '更新', color: 'blue' },
  DELETE: { text: '删除', color: 'red' },
}
```

**正确做法**:
```typescript
// ✅ 查看原始代码,确保完整
git show HEAD~1:src/components/InvoiceHistoryTab.tsx

// 原始代码有 10 个类型
typeMap: {
  UPLOAD: { text: '上传发票', color: 'blue' },
  OCR_START: { text: '开始OCR', color: 'cyan' },
  OCR_SUCCESS: { text: 'OCR成功', color: 'green' },
  OCR_FAILED: { text: 'OCR失败', color: 'red' },
  OCR_RETRY: { text: '重试OCR', color: 'orange' },
  MANUAL_EDIT: { text: '手动编辑', color: 'orange' },
  LINK_ORDER: { text: '关联订单', color: 'purple' },
  UNLINK_ORDER: { text: '取消关联', color: 'magenta' },
  FIELD_CONFIRM: { text: '确认字段', color: 'green' },
  DELETE: { text: '删除发票', color: 'red' },
}
```

### 陷阱 3: TypeScript 无法检测

**场景**:字段名错误但 TypeScript 不报错

```typescript
// ❌ TypeScript 不会报错(changedAt 在类型定义中存在)
dataIndex: 'changedAt'  // 类型检查通过
render: (val: string) => new Date(val).toLocaleString()
// 运行时:val 为 undefined → Invalid Date
```

**正确做法**:
```typescript
// ✅ 运行时测试 + 防御性编程
dataIndex: 'createdAt'
render: (val: string) => {
  if (!val) return '-'
  try {
    return new Date(val).toLocaleString('zh-CN')
  } catch {
    return val
  }
}
```

### 陷阱 4: rowKey 使用可选字段

**场景**:rowKey 使用了可能为 undefined 的字段

**错误做法**:
```typescript
// ❌ changedAt 可能为 undefined
rowKey={(record, index) => `${record.changedAt}-${index}`}
// 结果:undefined-0, undefined-1 → key 重复
```

**正确做法**:
```typescript
// ✅ 使用必填字段 id
rowKey={(record) => record.id}
```

### 陷阱 5: 同步覆盖时未考虑"源端缺失"和"人工调整"

**场景**:从外部源(雷珏、ERP、CRM)定时/手动同步数据到本系统,每次同步都直接覆盖目标字段。

#### 风险 5.1:源端字段为 null/缺失 → 清空目标端已有值

```java
// ❌ 源端这次没返回 categoryId,目标端 categoryId 被清成 null
public void syncFromExternal(ExternalDetail detail) {
    Product product = productRepository.findById(detail.getProductId()).orElseThrow();
    Long categoryId = resolveCategory(detail);  // 可能返回 null
    product.setCategoryId(categoryId);  // null 也覆盖 → 用户之前手动设置的分类被清空
    productRepository.save(product);
}

// ✅ 源端缺失则不覆盖
public void syncFromExternal(ExternalDetail detail) {
    Product product = productRepository.findById(detail.getProductId()).orElseThrow();
    Long categoryId = resolveCategory(detail);
    if (categoryId != null && !Objects.equals(product.getCategoryId(), categoryId)) {
        product.setCategoryId(categoryId);
        productRepository.save(product);
    }
}
```

#### 风险 5.2:用户手动调整后被下一次同步覆盖

**场景**:用户在系统里把雷珏导入的商品分类从「家居」改到「办公用品」,下次雷珏导入又强制覆盖回「家居」→ 用户操作被悄悄丢弃。

**伴随策略(last-sync-value pattern)**:在 mapping 表里记录"上次同步时给目标端的值",再覆盖前判断目标端是否仍等于该值。如果不等说明用户手动改过,跳过覆盖。

```java
// 1. mapping 表新增 last_category_id 字段
@Entity
public class LeijueProductMapping {
    private Long productId;
    private Long lastCategoryId;  // 上次同步时设置的 categoryId
    // ...
}

// 2. 同步时按"伴随策略"判定
private boolean syncCategoryField(Product product, Long newCategoryId, Long lastCategoryId) {
    if (newCategoryId == null) return false;  // 源缺失不动(风险 5.1)

    boolean isInitial = product.getCategoryId() == null;
    boolean followingLastSync = Objects.equals(product.getCategoryId(), lastCategoryId);

    if (isInitial || followingLastSync) {
        product.setCategoryId(newCategoryId);
        return true;
    } else {
        log.info("跳过覆盖,目标已被人工调整: productId={}, current={}, lastSync={}, source={}",
                product.getId(), product.getCategoryId(), lastCategoryId, newCategoryId);
        return false;
    }
}

// 3. 同步成功后更新 lastCategoryId
if (newCategoryId != null) {
    mapping.setLastCategoryId(newCategoryId);
}
```

#### 决策矩阵

| 源端值 | 目标当前值 == lastSyncValue | 决策 |
|--------|----------------------------|------|
| null | 任意 | **不动**(源缺失不清空) |
| 有值 | true(仍是上次同步值) | **覆盖**(用户未改过,跟随同步) |
| 有值 | false(与上次不一致) | **跳过**(用户改过,不要覆盖) |
| 有值 | 目标为 null | **覆盖**(首次同步) |

#### 何时不需要伴随策略

- 不可由用户编辑的字段(如外部唯一 ID、订单号、外部状态码):直接覆盖即可
- 计算字段(如统计快照):每次重算覆盖
- 主数据强一致场景(如供应商目录):明确以外部为准

#### 检查清单

- [ ] 同步流程里写 `entity.setXxx(newValue)` 前是否有 null 判断
- [ ] 源端字段为 null 时是否会错误清空目标端
- [ ] 用户可编辑的字段是否考虑"人工调整不被覆盖"
- [ ] 需要伴随策略的字段是否在 mapping 表里有 `last_xxx` 列
- [ ] 跳过同步时是否打 `log.info` 便于排查

---

## 验证流程

### 1. 静态检查

```bash
# TypeScript 类型检查
npm run type-check

# ESLint 检查
npm run lint
```

### 2. 运行时测试

- [ ] 在开发环境中测试功能
- [ ] 检查是否显示 "Invalid Date"
- [ ] 检查是否显示 "undefined" 或空白
- [ ] 检查枚举值是否都有对应的映射
- [ ] 检查 rowKey 是否唯一

### 3. 对比验证

```bash
# 查看原始代码
git show HEAD~1:src/components/InvoiceHistoryTab.tsx

# 制作对比清单
| 字段 | 原始代码 | 重构后 | 状态 |
|------|---------|--------|------|
| 时间字段 | createdAt | changedAt | ❌ 错误 |
| 操作类型 | operationType | changeType | ❌ 错误 |
| 枚举映射 | 10 个 | 3 个 | ❌ 不完整 |
| rowKey | record.id | record.changedAt | ❌ 错误 |
```
