- Task 5：expectImportLog 的行数参数显式转 int64。database/sql 会把实参归一成 driver.Value（int→int64），sqlmock 按类型比对，传 Go int 必然匹配不上 - Task 5：expectImportLog 补 fileName 参数，模板非法那条用例传的文件名与其它用例不同 - Task 5：事务内 SQL 的期望顺序改为「推进 code_rules → 分批 INSERT」， 与已提交的 ImportTx 实现（material.go:480 在 :485 之前）一致 - Task 6：测试片段补上缺失的 strings import 按修正后的片段替换 internal/service/material_import_test.go 实跑，5 个用例全通过。

# 物料批量导入实现计划
|
||
|
||
> **For agentic workers:** 使用 `superpowers:executing-plans` 按任务执行；步骤使用复选框（`- [ ]`）追踪。
|
||
|
||
**Goal:** 物料页面提供「下载模板」与「批量导入」两个入口，用户上传填好的 .xlsx 后，后端逐行校验并在同一个请求内事务入库，失败时整批不入库并返回逐行错误明细。
|
||
|
||
**Architecture:** 新增 `internal/service/material_import*.go` 负责 xlsx 解析、模板生成与逐行校验；`internal/repository/material.go` 新增批量入库方法（单事务内锁编码规则、分配编码、分批多值插入）；`internal/handler/material_import.go` 暴露两个 HTTP 接口。每次导入（无论成败）写一条 `material_import_logs` 记录；逐行错误只在响应里返回，不落库。
|
||
|
||
**Tech Stack:** Go 1.21、Gin、MySQL 8.0、`github.com/xuri/excelize/v2 v2.8.1`、sqlmock、Vue 3、Pinia、Element Plus、Vitest。
|
||
|
||
**Spec:** 本计划正文「设计约定」一节即本次交付的完整规格（源自需求方给出的《物料批量导入功能设计（最终版）》及后续澄清）。用户故事 `docs/MMS-用户故事-v2.3.md` 的 BAT-001、5.8.1 为背景需求。
|
||
|
||
## Global Constraints
|
||
|
||
- Excel 库固定 `github.com/xuri/excelize/v2 v2.8.1`：**不得升级到 v2.9+**，v2.9 起要求 Go ≥1.23，而 `Dockerfile` 使用 `golang:1.21-alpine`（已实测 v2.8.1 可编译、可 `OpenReader`/`WriteToBuffer`）。
|
||
- 文件限制：仅 `.xlsx`，≤ 5 MB，数据区 ≤ 20,000 行（不含表头）。
|
||
- 首版仅支持**新增**物料，不做更新、不做分类/单位的自动创建。
|
||
- 物料编码由系统按小类编码规则生成，**不接受 Excel 中的编码列**；小类未配置启用的编码规则时该行报错。
|
||
- 任意一行校验失败 → 整批不入库，返回全部逐行错误。
|
||
- 所有接口必须挂 `middleware.AuthMiddleware(), middleware.OrganizationMiddleware()`，公司取服务端上下文，忽略请求体伪造值。
|
||
- 注释、提交信息、用户可见文案全部用中文（与仓库既有风格一致）。
|
||

||
|
||
## 设计约定
|
||
|
||
### 1. 流程
|
||
|
||
下载模板 → 填写 → 上传 → 后端解析 → 逐行校验 → **全部通过即在同一个请求内事务入库** → 返回结果。
|
||
|
||
**已确认去掉「预览确认」环节**：不再有暂存任务 ID、不再有确认接口，也不存在"确认时重新校验"。校验失败时整批不入库，错误明细随响应返回。
|
||
|
||
### 2. 模板
|
||
|
||
两个工作表：
|
||
|
||
- `填写说明`：字段名、是否必填、示例、填写规则。
|
||
- `物料数据`：第 1 行表头，数据从第 2 行开始。
|
||
|
||
模板生成的表头是 5 列：`物料名称`、`规格`、`单位`、`大类`、`小类`。解析时**按列名定位，不按列位置**：
|
||
|
||
- 必填列 `物料名称`、`大类`、`小类` 缺任何一列 → 报「模板格式不正确，请重新下载最新模板」；
|
||
- 选填列 `规格`、`单位` 可以整列删掉，取值按空处理；
|
||
- 列顺序可以随意调整；
|
||
- 表头允许带首尾空格与末尾的 `*` 必填标记；不认识的列忽略。
|
||
|
||
「单元格留空」和「整列缺失」是两回事：规格与单位留空属于合法的选填，不会报错；只有必填列缺失才判定模板不合法。
|
||
|
||
分类**按名称填写**，后端按「大类名 + 小类名」组合在本公司内匹配（小类名在本公司内会重名，如「其他」在 A07/B07/C03/D04/F05 都叫「其他」，因此必须两级组合）。单位按名称匹配，同时兼容按编码匹配（如 `kg` 与 `千克`）。
|
||
|
||
### 3. 接口
|
||
|
||
| 方法 | 路径 | 说明 |
|
||
| ---- | ------------------------------- | -------------------------------------- |
|
||
| GET | `/api/material-import/template` | 下载 xlsx 模板，返回文件流 |
|
||
| POST | `/api/material-import` | `multipart/form-data`，字段名 `file`，上传即入库 |
|
||
|
||
**路由必须挂在独立前缀 `/material-import`**：`materials` 组下已有 `GET /:id`，gin 的路由树不允许同一段既有静态前缀又有 `:id` 通配，把 `/materials/import/...` 加进该组会直接 panic。
|
||
|
||
成功响应 `201 Created`：
|
||
|
||
```json
|
||
{
|
||
"code": 0,
|
||
"message": "成功导入 200 条物料",
|
||
"data": { "total_rows": 200, "success_rows": 200, "failed_rows": 0, "errors": [] }
|
||
}
|
||
```
|
||
|
||
校验失败 `400 Bad Request`（HTTP 状态 400，但 `data` 带完整明细）：
|
||
|
||
```json
|
||
{
|
||
"code": 400,
|
||
"message": "有 3 行校验未通过，本次未导入任何数据",
|
||
"data": {
|
||
"total_rows": 200, "success_rows": 0, "failed_rows": 3,
|
||
"errors": [
|
||
{ "row": 3, "data": { "name": "", "spec": "M8x30", "unit": "个", "major": "机械结构类", "minor": "标准件" }, "reason": "物料名称不能为空" }
|
||
]
|
||
}
|
||
}
|
||
```
|
||
|
||
`row` 是 Excel 中的真实行号（从 1 开始，含表头行），用户可直接对着 Excel 定位。
|
||
|
||
### 4. 校验规则（逐行）
|
||
|
||
| 列 | 规则 |
|
||
| ---- | ------------------------------------------- |
|
||
| 物料名称 | 必填，去首尾空格后非空，≤ 200 字 |
|
||
| 规格 | 选填，≤ 200 字 |
|
||
| 单位 | 选填；为空时默认「个」。非空时必须在当前公司已启用单位中按名称或编码匹配到 |
|
||
| 大类 | 必填，必须是当前公司已启用的顶层分类名称 |
|
||
| 小类 | 必填，必须是该大类下已启用的小类名称 |
|
||
| 编码规则 | 该小类必须存在 `status='active'` 的 `code_rules` 记录 |
|
||
|
||
同一行可产生多条原因，用中文分号连接。
|
||
|
||
### 5. 编码生成与并发
|
||
|
||
- 入库事务内按 `category_id` **升序**依次 `SELECT ... FOR UPDATE` 锁定 `code_rules` 行（升序加锁避免多事务互相等待造成死锁）。
|
||
- 每个小类一次性取出已占用编码集合（`SELECT material_code FROM materials WHERE organization_id=? AND material_code LIKE ?`），在内存里顺序分配，跳过已占用号（库中可能存在手工录入、落在号段内的编码）。
|
||
- 分配完成后 `UPDATE code_rules SET next_sequence = ?`。
|
||
- 校验阶段不生成编码，预览/响应里也不承诺最终编码。
|
||
|
||
### 6. 事务与记录
|
||
|
||
- 整批入库在**一个事务**内：分配编码 → 分批多值 INSERT 物料（每批 500 行）→ 回填 ID → 批量写 `material_logs`（每条物料一条 `CREATE` 审计记录，与单条新增保持一致）。
|
||
- 任一行插入失败则整体回滚。
|
||
- 每次导入（成功或失败）都写一条 `material_import_logs`：操作人、公司、时间、文件名、总行数、成功数、失败数、状态、失败原因摘要。**逐行错误明细不落库**，只在响应里返回。
|
||
|
||
### 7. 权限
|
||
|
||
沿用物料新增的权限口径：仅要求登录 + 当前公司可访问（与 `POST /api/materials` 相同，不额外要求 `super_admin`）。公司取自 `X-Organization-ID` 经中间件校验后的上下文。
|
||
|
||
### 8. 防止重复提交
|
||
|
||
去掉预览与暂存后没有服务端幂等键（设计第 7 点原文的「任务 ID 作为幂等键」随预览一起取消），靠两道前端约束：
|
||
|
||
- 保存互斥：整个上传流程包在 `runWithSaving` 里，飞行期间禁止切换公司；
|
||
- 入口状态：`importing` 标志守住 `triggerImport`，上传期间再点不会重新选文件；`handleImportFile` 在发起请求前就把 input 的 `value` 清空，避免同一个文件连续触发两次 `change`。
|
||
|
||
后端不做文件级去重：同一份文件重复上传会真的导入两遍（编码不同）。这是首版明确接受的取舍，见文末「已知取舍」。

## Task 1: 数据库表与模型
|
||
|
||
**Files:**
|
||
|
||
- Create: `internal/model/material_import.go`
|
||
- Create: `scripts/upgrades/2026-10-10-material-bulk-import.sql`
|
||
- Modify: `scripts/init.sql`（在 `code_rules` 建表语句之后追加）
|
||
|
||
**Interfaces:**
|
||
|
||
- Produces: `model.MaterialImportRow`、`model.MaterialImportError`、`model.MaterialImportResult`、`model.MaterialImportLog`
|
||
|
||
- Produces: 表 `material_import_logs`
|
||
|
||
- [ ] **Step 1: 在 init.sql 增加建表语句**
|
||
|
||
在 `scripts/init.sql` 的 `code_rules` 那行之后插入：
|
||
|
||
```sql
|
||
CREATE TABLE material_import_logs (id BIGINT AUTO_INCREMENT PRIMARY KEY, organization_id BIGINT NOT NULL, operator VARCHAR(100) NOT NULL, file_name VARCHAR(255) NOT NULL, total_rows INT NOT NULL DEFAULT 0, success_rows INT NOT NULL DEFAULT 0, failed_rows INT NOT NULL DEFAULT 0, status VARCHAR(20) NOT NULL, failure_reason VARCHAR(1000) NOT NULL DEFAULT '', created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP, KEY idx_material_import_logs_org_created(organization_id,created_at), FOREIGN KEY(organization_id) REFERENCES organizations(id)) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
|
||
```
|
||
|
||
- [ ] **Step 2: 写增量升级脚本**
|
||
|
||
创建 `scripts/upgrades/2026-10-10-material-bulk-import.sql`，内容与上一步完全相同的 `CREATE TABLE material_import_logs`，并在末尾追加迁移登记：
|
||
|
||
```sql
|
||
INSERT INTO schema_migrations(version,status,completed_at,details) VALUES('2026-10-10-material-bulk-import','completed',NOW(),JSON_OBJECT('version','2026-10-10-material-bulk-import','source','upgrade'));
|
||
```
|
||
|
||
- [ ] **Step 3: 写模型**
|
||
|
||
创建 `internal/model/material_import.go`：
|
||
|
||
```go
|
||
package model
|
||
|
||
import "time"
|
||
|
||
// MaterialImportRow 是解析后的一行原始数据。Row 保留 Excel 真实行号（从 1
|
||
// 开始、含表头行），校验失败时用它定位，用户可直接对着 Excel 找。
|
||
type MaterialImportRow struct {
|
||
Row int
|
||
Name string
|
||
Spec string
|
||
Unit string
|
||
MajorName string
|
||
MinorName string
|
||
}
|
||
|
||
// Data 返回该行的原始内容，用于错误明细里的"原始数据"。
|
||
func (r MaterialImportRow) Data() map[string]string {
|
||
return map[string]string{
|
||
"name": r.Name,
|
||
"spec": r.Spec,
|
||
"unit": r.Unit,
|
||
"major": r.MajorName,
|
||
"minor": r.MinorName,
|
||
}
|
||
}
|
||
|
||
// MaterialImportError 是一行的失败原因，Reason 可能包含多条，用中文分号连接。
|
||
type MaterialImportError struct {
|
||
Row int `json:"row"`
|
||
Data map[string]string `json:"data"`
|
||
Reason string `json:"reason"`
|
||
}
|
||
|
||
// MaterialImportResult 是一次导入的返回值。校验失败时 SuccessRows 为 0、
|
||
// Errors 非空；成功时 Errors 为空数组（不是 null）。
|
||
type MaterialImportResult struct {
|
||
TotalRows int `json:"total_rows"`
|
||
SuccessRows int `json:"success_rows"`
|
||
FailedRows int `json:"failed_rows"`
|
||
Errors []MaterialImportError `json:"errors"`
|
||
}
|
||
|
||
// MaterialImportLog 是一次导入的持久化记录，成功或失败都会写一条。
|
||
type MaterialImportLog struct {
|
||
ID int64 `json:"id"`
|
||
OrganizationID int64 `json:"organization_id"`
|
||
Operator string `json:"operator"`
|
||
FileName string `json:"file_name"`
|
||
TotalRows int `json:"total_rows"`
|
||
SuccessRows int `json:"success_rows"`
|
||
FailedRows int `json:"failed_rows"`
|
||
Status string `json:"status"`
|
||
FailureReason string `json:"failure_reason"`
|
||
CreatedAt time.Time `json:"created_at"`
|
||
}
|
||
|
||
const (
|
||
MaterialImportStatusSuccess = "success"
|
||
MaterialImportStatusFailed = "failed"
|
||
)
|
||
```
|
||
|
||
- [ ] **Step 4: 编译验证**
|
||
|
||
Run: `go build ./...`
|
||
Expected: 通过。
|
||
|
||
- [ ] **Step 5: 重建本地数据库（旧库无增量升级路径）**
|
||
|
||
Run: `docker compose down -v && docker compose up -d db`
|
||
说明：本地库只认 `init.sql`，不执行 `upgrades/` 脚本；这一步之后表才会存在。
|
||
|
||
- [ ] **Step 6: Commit**
|
||
|
||
```bash
|
||
git add scripts/init.sql scripts/upgrades/2026-10-10-material-bulk-import.sql internal/model/material_import.go
|
||
git commit -m "feat: 新增物料导入记录表与模型"
|
||
```
|
||
|
||

|
||
|
||
## Task 2: Excel 模板生成与解析
|
||
|
||
**Files:**
|
||
|
||
- Create: `internal/service/material_import_excel.go`
|
||
- Test: `internal/service/material_import_excel_test.go`
|
||
- Modify: `go.mod`、`go.sum`
|
||
|
||
**Interfaces:**
|
||
|
||
- Produces: `BuildMaterialImportTemplate() ([]byte, error)`
|
||
|
||
- Produces: `ParseMaterialImportFile(r io.Reader) ([]model.MaterialImportRow, error)`
|
||
|
||
- Produces: 错误变量 `ErrImportTemplateInvalid`、`ErrImportTooManyRows`
|
||
|
||
- [ ] **Step 1: 引入 excelize v2.8.1**
|
||
|
||
```bash
|
||
go get github.com/xuri/excelize/v2@v2.8.1
|
||
```
|
||
|
||
Run: `grep excelize go.mod`
|
||
Expected: `github.com/xuri/excelize/v2 v2.8.1`（**不可为 v2.9+**）
|
||
|

## Task 3: 批量入库（编码分配 + 事务插入）
|
||
|
||
**Files:**
|
||
|
||
- Modify: `internal/repository/material.go`（追加方法，不改动已有函数）
|
||
- Modify: `internal/repository/material_log.go`（追加 `CreateBatchTx`）
|
||
- Test: `internal/repository/material_import_test.go`
|
||
|
||
**Interfaces:**
|
||
|
||
- Consumes: `model.Material`、`sqlExecer`（已存在）、`lockCodeRule`（已存在，`material.go:84`）
|
||
|
||
- Produces: `(*MaterialRepo) ImportTx(tx *sql.Tx, organizationID int64, materials []*model.Material) error`
|
||
|

**注意：** 仓库里 `insertMaterialStmt` 定义在 `internal/service/material_test.go`（service 包），repository 包内没有同名常量。批量插入是**多值**语句，所以要在 `internal/repository/material_import_test.go` 里按参与行数拼出期望文本。测试里用到的是两行一批：
|
||
|
||
```go
|
||
const insertMaterialBatchStmt = `INSERT INTO materials (organization_id, material_code, name, material_image, spec, manufacturer_model, category_id, base_unit_id, unit, status, version) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?), (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)`
|
||
```
|
||
|
||
行数更多的场景（如 501 行那一条）用 `mock.ExpectExec("INSERT INTO materials")` 松匹配即可，不必拼 501 组占位符。

在 `pkg/response/response.go` 的 `Error` 之后追加：
|
||
|
||
```go
|
||
// ErrorWithData 返回带业务数据的错误响应。批量导入校验失败时需要把逐行错误
|
||
// 一起带回去，不能只给一句话。
|
||
func ErrorWithData(c *gin.Context, httpStatus int, message string, data interface{}) {
|
||
c.JSON(httpStatus, Response{
|
||
Code: httpStatus,
|
||
Message: message,
|
||
Data: data,
|
||
})
|
||
}
|
||
```
|
||
|
||
- [ ] **Step 2: 写失败的测试**
|
||
|
||
创建 `internal/handler/material_import_test.go`：
|
||
|
||
```go
|
||
package handler
|
||
|
||
import (
|
||
"net/http"
|
||
"net/http/httptest"
|
||
"strings"
|
||
"testing"
|
||
|
||
"github.com/gin-gonic/gin"
|
||
"github.com/wmms/wmms/pkg/response"
|
||
)
|
||
|
||
func TestErrorWithDataKeepsPayload(t *testing.T) {
|
||
gin.SetMode(gin.TestMode)
|
||
recorder := httptest.NewRecorder()
|
||
c, _ := gin.CreateTestContext(recorder)
|
||
|
||
response.ErrorWithData(c, http.StatusBadRequest, "有 1 行校验未通过", map[string]interface{}{
|
||
"total_rows": 1, "failed_rows": 1,
|
||
})
|
||
|
||
if recorder.Code != http.StatusBadRequest {
|
||
t.Fatalf("status = %d, want 400", recorder.Code)
|
||
}
|
||
body := recorder.Body.String()
|
||
if !strings.Contains(body, "有 1 行校验未通过") || !strings.Contains(body, `"failed_rows":1`) {
|
||
t.Fatalf("body = %s", body)
|
||
}
|
||
}
|
||
```
|
||
|
||
并在 `internal/handler/routes_test.go` 的 `TestPhaseOneAndLegacyRoutesAreRegistered` 里，往 `want` 切片的 `"POST /api/logs"` 那一行之后追加（该切片每项是 `"方法 路径"` 字符串）：
|
||
|
||
```go
|
||
"GET /api/material-import/template", "POST /api/material-import",
|
||
```
|
||
|
||
同文件的 `TestOrganizationBusinessRoutesRequireHeaderBeforeHandler` 会自动遍历到这两条新路由（它们不在豁免前缀里），断言缺少 `X-Organization-ID` 时返回 400，因此只要路由挂上了 `OrganizationMiddleware()` 就会被它覆盖，无需另写权限用例。
|
||
|
||
- [ ] **Step 3: 跑测试确认失败**
|
||
|
||
Run: `go test ./internal/handler/ -run 'ErrorWithData|Routes' -v`
|
||
Expected: FAIL（`ErrorWithData` 未定义 / 路由缺失）
|
||
|
||
- [ ] **Step 4: 实现 handler**
|
||
|
||
创建 `internal/handler/material_import.go`：
|
||
|
||
```go
|
||
package handler
|
||
|
||
import (
|
||
"errors"
|
||
"net/http"
|
||
"net/url"
|
||
"strconv"
|
||
|
||
"github.com/gin-gonic/gin"
|
||
"github.com/wmms/wmms/internal/middleware"
|
||
"github.com/wmms/wmms/internal/service"
|
||
"github.com/wmms/wmms/pkg/response"
|
||
)
|
||
|
||
// DownloadMaterialImportTemplate 返回物料导入模板文件。模板随代码生成，
|
||
// 不落盘，保证下载到的永远和当前校验规则一致。
|
||
func (h *Handler) DownloadMaterialImportTemplate(c *gin.Context) {
|
||
data, err := service.BuildMaterialImportTemplate()
|
||
if err != nil {
|
||
response.InternalError(c, "模板生成失败")
|
||
return
|
||
}
|
||
fileName := url.PathEscape("物料导入模板.xlsx")
|
||
c.Header("Content-Disposition", `attachment; filename="material-import-template.xlsx"; filename*=UTF-8''`+fileName)
|
||
c.Data(http.StatusOK, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", data)
|
||
}
|
||
|
||
// ImportMaterials 接收上传的 xlsx，校验通过即整批入库。
|
||
// 校验失败返回 400 且 data 里带逐行错误明细。
|
||
func (h *Handler) ImportMaterials(c *gin.Context) {
|
||
orgID, ok := organizationID(c)
|
||
if !ok {
|
||
return
|
||
}
|
||
|
||
file, err := c.FormFile("file")
|
||
if err != nil {
|
||
response.BadRequest(c, "请选择要导入的 xlsx 文件")
|
||
return
|
||
}
|
||
if file.Size > service.MaterialImportMaxBytes {
|
||
response.BadRequest(c, "文件超过 5MB 上限")
|
||
return
|
||
}
|
||
|
||
source, err := file.Open()
|
||
if err != nil {
|
||
response.BadRequest(c, "文件读取失败")
|
||
return
|
||
}
|
||
defer source.Close()
|
||
|
||
operator := middleware.GetCurrentUsername(c)
|
||
if operator == "" {
|
||
operator = "系统"
|
||
}
|
||
|
||
result, err := h.materialImportSvc.Import(orgID, operator, file.Filename, source)
|
||
if err != nil {
|
||
if errors.Is(err, service.ErrImportTemplateInvalid) || errors.Is(err, service.ErrImportTooManyRows) {
|
||
response.BadRequest(c, err.Error())
|
||
return
|
||
}
|
||
response.InternalError(c, err.Error())
|
||
return
|
||
}
|
||
if result.FailedRows > 0 {
|
||
response.ErrorWithData(c, http.StatusBadRequest,
|
||
"有 "+strconv.Itoa(result.FailedRows)+" 行校验未通过，本次未导入任何数据", result)
|
||
return
|
||
}
|
||
response.Created(c, "成功导入 "+strconv.Itoa(result.SuccessRows)+" 条物料", result)
|
||
}
|
||
```
|
||
|
||
- [ ] **Step 5: 注册路由与服务**
|
||
|
||
`internal/handler/api.go`：
|
||
|
||
1. `Handler` 结构体加字段：
|
||
|
||
```go
|
||
materialImportSvc *service.MaterialImportService
|
||
```
|
||
|
||
2. `NewHandler()` 加：
|
||
|
||
```go
|
||
materialImportSvc: service.NewMaterialImportService(),
|
||
```
|
||
|
||
3. 在 `materials` 路由组之后加（**必须是独立前缀**）：
|
||
|
||
```go
|
||
// 物料批量导入单独挂前缀：materials 组已有 GET /:id，
|
||
// gin 的路由树不允许同段既有静态前缀又有通配参数。
|
||
materialImport := api.Group("/material-import")
|
||
materialImport.Use(middleware.AuthMiddleware(), middleware.OrganizationMiddleware())
|
||
{
|
||
materialImport.GET("/template", h.DownloadMaterialImportTemplate)
|
||
materialImport.POST("", h.ImportMaterials)
|
||
}
|
||
```
|
||
|
||
- [ ] **Step 6: 跑测试确认通过**
|
||
|
||
Run: `go test ./internal/handler/ -v -run 'ErrorWithData|Routes'`
|
||
Expected: PASS
|
||
|
||
- [ ] **Step 7: 起服务验证路由不 panic**
|
||
|
||
Run: `go build -o server.exe ./cmd/server && echo BUILD_OK`
|
||
Expected: `BUILD_OK`（gin 路由冲突会在注册时 panic，构建通过后由下一步的路由测试兜住）
|
||
|
||
- [ ] **Step 8: Commit**
|
||
|
||
```bash
|
||
git add internal/handler/material_import.go internal/handler/material_import_test.go internal/handler/api.go internal/handler/routes_test.go pkg/response/response.go
|
||
git commit -m "feat: 物料导入与模板下载接口"

|
||
## Task 7: 前端 API 与工具
|
||
|
||
**Files:**
|
||
|
||
- Modify: `frontend/src/api/materials.js`
|
||
- Create: `frontend/src/utils/exportCsv.js`
|
||
- Test: `frontend/src/utils/exportCsv.test.js`
|
||
|
||
**Interfaces:**
|
||
|
||
- Produces: `materialsApi.importFile(formData)`、`materialsApi.downloadImportTemplate()`
|
||
|
||
- Produces: `buildCsv(rows)`、`downloadCsv(fileName, csv)`
|
||
|
||
- [ ] **Step 1: 写失败的测试**
|
||
|
||
创建 `frontend/src/utils/exportCsv.test.js`：
|
||
|
||
```js
|
||
import { describe, expect, test } from 'vitest'
|
||
import { buildCsv } from './exportCsv'
|
||
|
||
describe('buildCsv', () => {
|
||
test('用逗号分隔并在行尾换行', () => {
|
||
const csv = buildCsv([
|
||
['行号', '失败原因'],
|
||
[3, '物料名称不能为空']
|
||
])
|
||
expect(csv).toBe('行号,失败原因\r\n3,物料名称不能为空\r\n')
|
||
})
|
||
|
||
test('包含逗号、引号、换行的字段用双引号包裹并转义', () => {
|
||
const csv = buildCsv([['规格', '备注'], ['M8,30', '含"引号"'], ['两\n行', '']])
|
||
expect(csv).toBe('规格,备注\r\n"M8,30","含""引号"""\r\n"两\n行",\r\n')
|
||
})
|
||
})
|
||
```
|
||
|
||
- [ ] **Step 2: 跑测试确认失败**
|
||
|
||
Run: `cd frontend && npx vitest run src/utils/exportCsv.test.js`
|
||
Expected: FAIL（模块不存在）
|
||
|
||
- [ ] **Step 3: 实现**
|
||
|
||
创建 `frontend/src/utils/exportCsv.js`：
|
||
|
||
```js
|
||
// 生成 CSV 文本。带 UTF-8 BOM，Excel 打开中文才不会乱码；字段里的
|
||
// 逗号、引号、换行按 RFC 4180 用双引号包裹并转义。
|
||
export function buildCsv(rows) {
|
||
const lines = rows.map(row => row.map(escapeCsvCell).join(','))
|
||
return '' + lines.map(line => line + '\r\n').join('')
|
||
}
|
||
|
||
function escapeCsvCell(value) {
|
||
const text = value === null || value === undefined ? '' : String(value)
|
||
if (/[",\r\n]/.test(text)) {
|
||
return `"${text.replace(/"/g, '""')}"`
|
||
}
|
||
return text
|
||
}
|
||
|
||
// 触发浏览器下载。用 Blob + a[download]，不依赖任何第三方库。
|
||
export function downloadCsv(fileName, csv) {
|
||
const blob = new Blob([csv], { type: 'text/csv;charset=utf-8' })
|
||
const url = URL.createObjectURL(blob)
|
||
const link = document.createElement('a')
|
||
link.href = url
|
||
link.download = fileName
|
||
document.body.appendChild(link)
|
||
link.click()
|
||
document.body.removeChild(link)
|
||
URL.revokeObjectURL(url)
|
||
}
|
||
```
|
||
|
||
- [ ] **Step 4: 跑测试确认通过**
|
||
|
||
Run: `cd frontend && npx vitest run src/utils/exportCsv.test.js`
|
||
Expected: PASS
|
||
|
||
- [ ] **Step 5: 加 API**
|
||
|
||
在 `frontend/src/api/materials.js` 的 `materialsApi` 对象里追加两个方法（放在 `uploadImage` 之后）：
|
||
|
||
```js
|
||
importFile(formData) {
|
||
// silent：校验失败的明细要自己弹窗展示，不让拦截器先弹一句笼统提示
|
||
return request.post('/material-import', formData, {
|
||
headers: { 'Content-Type': 'multipart/form-data' },
|
||
silent: true
|
||
})
|
||
},
|
||
downloadImportTemplate() {
|
||
// 下载走原生 fetch：响应是文件流，axios 拦截器只认 JSON 的 code 字段
|
||
return fetch('/api/material-import/template', {
|
||
headers: downloadHeaders()
|
||
})
|
||
}
|
||
```
|
||
|
||
并在文件顶部补上取头信息的辅助：
|
||
|
||
```js
|
||
import { getOrganizationId } from '../utils/organizationContext'
|
||
|
||
// 下载接口绕开 axios，得自己带令牌与当前公司，否则 401 / 400。
|
||
// 令牌沿用拦截器同款读法（localStorage），避免在 API 模块里依赖 Pinia 激活时序。
|
||
function downloadHeaders() {
|
||
const token = localStorage.getItem('wmms_token')
|
||
const organizationId = getOrganizationId()
|
||
return {
|
||
...(token ? { Authorization: `Bearer ${token}` } : {}),
|
||
...(organizationId ? { 'X-Organization-ID': String(organizationId) } : {})
|
||
}
|
||
}
|
||
```
|
||
|
||
- [ ] **Step 6: 跑前端测试**
|
||
|
||
Run: `cd frontend && npx vitest run src/api`
|
||
Expected: 无新增失败
|
||
|
||
- [ ] **Step 7: Commit**
|
||
|
||
```bash
|
||
git add frontend/src/api/materials.js frontend/src/utils/exportCsv.js frontend/src/utils/exportCsv.test.js
|
||
git commit -m "feat: 物料导入前端接口与 CSV 导出工具"

|
||
**Files:**
|
||

- Create: `frontend/src/components/business/MaterialImportResult.vue`
|
||
- Test: `frontend/src/components/business/MaterialImportResult.test.js`

|
||
|
||
- [ ] **Step 1: 写失败的测试**
|
||
|

|
||
const now = new Date()
|
||
const pad = value => String(value).padStart(2, '0')
|
||
return `${now.getFullYear()}${pad(now.getMonth() + 1)}${pad(now.getDate())}`
|
||
+ `-${pad(now.getHours())}${pad(now.getMinutes())}${pad(now.getSeconds())}`
|
||
}
|

</script>
|

</style>
|

```
|
||
|
||
**注意：** `BasePagination` 的 props 是 `currentPage` / `pageSize` / `total`，emit 的是 `change`（`frontend/src/components/business/BasePagination.vue:18-24`），上面用法与之一致。
|
||
|
||
- [ ] **Step 4: 跑测试确认通过**
|
||
|
||
Run: `cd frontend && npx vitest run src/components/business/MaterialImportResult.test.js`
|
||
Expected: PASS（3 个测试）
|
||
|
||
- [ ] **Step 5: Commit**
|
||
|
||
```bash
|
||
git add frontend/src/components/business/MaterialImportResult.vue frontend/src/components/business/MaterialImportResult.test.js
|
||
git commit -m "feat: 物料导入结果弹窗组件"
|
||
```

|
||
## Task 9: 物料页面接入
|
||
|
||
**Files:**
|
||
|
||
- Modify: `frontend/src/views/Materials.vue`
|
||
- Test: `frontend/src/views/Materials.test.js`（追加）
|
||
|
||
**Interfaces:**
|
||
|
||
- Consumes: `materialsApi.importFile`、`materialsApi.downloadImportTemplate`、`MaterialImportResult.vue`、`useSavingGuard`
|
||
|
||
- [ ] **Step 1: 写失败的测试**
|
||
|
||
在 `frontend/src/views/Materials.test.js` 末尾追加（沿用文件里已有的 `mountMaterials()`、mock 结构）：
|
||
|
||
```js
|
||
test('批量导入成功后提示成功并刷新列表', async () => {
|
||
materialsApi.importFile.mockResolvedValue({
|
||
data: { total_rows: 2, success_rows: 2, failed_rows: 0, errors: [] }
|
||
})
|
||
|
||
const wrapper = mountMaterials()
|
||
await flushPromises()
|
||
|
||
await setupState(wrapper).handleImportFile({
|
||
target: { files: [new File(['x'], '物料.xlsx')], value: '物料.xlsx' }
|
||
})
|
||
await flushPromises()
|
||
|
||
expect(materialsApi.importFile).toHaveBeenCalled()
|
||
expect(materialsStore.fetchMaterials).toHaveBeenCalled()
|
||
expect(ElMessage.success).toHaveBeenCalledWith('成功导入 2 条物料')
|
||
wrapper.unmount()
|
||
})
|
||
|
||
test('批量导入失败时展示错误明细且不刷新列表', async () => {
|
||
const error = new Error('校验未通过')
|
||
error.response = {
|
||
data: {
|
||
code: 400,
|
||
message: '有 1 行校验未通过，本次未导入任何数据',
|
||
data: {
|
||
total_rows: 1, success_rows: 0, failed_rows: 1,
|
||
errors: [{ row: 2, data: { name: '', spec: '', unit: '', major: '', minor: '' }, reason: '物料名称不能为空' }]
|
||
}
|
||
}
|
||
}
|
||
materialsApi.importFile.mockRejectedValue(error)
|
||
|
||
const wrapper = mountMaterials()
|
||
await flushPromises()
|
||
|
||
await setupState(wrapper).handleImportFile({
|
||
target: { files: [new File(['x'], '物料.xlsx')], value: '物料.xlsx' }
|
||
})
|
||
await flushPromises()
|
||
|
||
expect(setupState(wrapper).importResult.failed_rows).toBe(1)
|
||
expect(materialsStore.fetchMaterials).not.toHaveBeenCalled()
|
||
wrapper.unmount()
|
||
})
|
||
```
|
||
|
||
**注意：** `Materials.test.js` 目前 mock 的是 `vi.mock('../stores/materials')` 与 `vi.mock('../../api/masterData')`，需要在顶部补 `vi.mock('../../api/materials')`，导出 `materialsApi`（含 `importFile`/`downloadImportTemplate` 两个 `vi.fn()`）；`ElMessage` 的 spy 若尚未建立，按文件里既有的 `vi.mock('element-plus')` 方式补齐。
|
||
|
||
- [ ] **Step 2: 跑测试确认失败**
|
||
|
||
Run: `cd frontend && npx vitest run src/views/Materials.test.js`
|
||
Expected: 新增的两个用例 FAIL
|
||
|
||
- [ ] **Step 3: 实现页面接入**
|
||
|
||
`frontend/src/views/Materials.vue` 改动：
|
||
|
||
1. 顶部按钮区（第 3-6 行）加两个按钮和一个隐藏的文件输入：
|
||
|
||
```vue
|
||
<div class="page-header">
|
||
<h2>物料主数据</h2>
|
||
<div class="header-actions">
|
||
<el-button @click="handleDownloadTemplate">下载模板</el-button>
|
||
<el-button @click="triggerImport">批量导入</el-button>
|
||
<el-button type="primary" @click="showAddModal">新增物料</el-button>
|
||
<input
|
||
ref="importInput"
|
||
type="file"
|
||
accept=".xlsx"
|
||
style="display: none"
|
||
@change="handleImportFile"
|
||
/>
|
||
</div>
|
||
</div>
|
||
```
|
||
|
||
2. 在页面底部加导入结果弹窗：
|
||
|
||
```vue
|
||
<el-dialog v-model="importDialogVisible" title="批量导入结果" width="900px" @closed="handleImportDialogClosed">
|
||
<MaterialImportResult v-if="importResult" :result="importResult" @close="importDialogVisible = false" />
|
||
</el-dialog>
|
||
```
|
||
|
||
3. `script setup` 里补充：
|
||
|
||
```js
|
||
import MaterialImportResult from '../components/business/MaterialImportResult.vue'
|
||
import { materialsApi } from '../api/materials'
|
||
|
||
const importInput = ref(null)
|
||
const importDialogVisible = ref(false)
|
||
const importResult = ref(null)
|
||
const importing = ref(false)
|
||
|
||
function triggerImport() {
|
||
if (importing.value) return
|
||
importInput.value?.click()
|
||
}
|
||
|
||
async function handleImportFile(event) {
|
||
const file = event.target.files?.[0]
|
||
// 清空 input，否则连续选同一个文件不会再触发 change
|
||
event.target.value = ''
|
||
if (!file) return
|
||
if (!file.name.toLowerCase().endsWith('.xlsx')) {
|
||
ElMessage.warning('只支持 .xlsx 文件')
|
||
return
|
||
}
|
||
if (file.size > 5 * 1024 * 1024) {
|
||
ElMessage.warning('文件不能超过 5MB')
|
||
return
|
||
}
|
||
|
||
const formData = new FormData()
|
||
formData.append('file', file)
|
||
|
||
importing.value = true
|
||
try {
|
||
// 导入是写请求：包进保存互斥，飞行期间禁止切换公司
|
||
const res = await runWithSaving(() => materialsApi.importFile(formData))
|
||
const result = res.data
|
||
await materialsStore.fetchMaterials(1, '', 'all')
|
||
searchKeyword.value = ''
|
||
ElMessage.success(`成功导入 ${result.success_rows} 条物料`)
|
||
} catch (e) {
|
||
// 校验失败时响应里带逐行明细，弹窗展示；其余错误交给拦截器之外的兜底提示
|
||
const detail = e?.response?.data?.data
|
||
if (detail && Array.isArray(detail.errors)) {
|
||
importResult.value = detail
|
||
importDialogVisible.value = true
|
||
} else if (!e?.response) {
|
||
console.error('批量导入失败:', e)
|
||
ElMessage.error(errorText(e, '批量导入失败'))
|
||
}
|
||
} finally {
|
||
importing.value = false
|
||
}
|
||
}
|
||
|
||
function handleImportDialogClosed() {
|
||
importResult.value = null
|
||
}
|
||
|
||
async function handleDownloadTemplate() {
|
||
try {
|
||
const res = await runWithSaving(() => materialsApi.downloadImportTemplate())
|
||
if (!res.ok) {
|
||
ElMessage.error('模板下载失败')
|
||
return
|
||
}
|
||
const blob = await res.blob()
|
||
const url = URL.createObjectURL(blob)
|
||
const link = document.createElement('a')
|
||
link.href = url
|
||
link.download = '物料导入模板.xlsx'
|
||
document.body.appendChild(link)
|
||
link.click()
|
||
document.body.removeChild(link)
|
||
URL.revokeObjectURL(url)
|
||
} catch (e) {
|
||
console.error('下载模板失败:', e)
|
||
ElMessage.error('模板下载失败')
|
||
}
|
||
}
|
||
```
|
||
|
||
4. `<style scoped>` 里补：
|
||
|
||
```css
|
||
.header-actions { display: flex; gap: 8px; }
|
||
```
|
||
|
||
**注意：** `errorText` 已在页面中导入（第 458 行附近在用），无需重复导入。`runWithSaving` 已有。
|
||
|
||
- [ ] **Step 4: 跑测试确认通过**
|
||
|
||
Run: `cd frontend && npx vitest run src/views/Materials.test.js`
|
||
Expected: PASS
|
||
|
||
- [ ] **Step 5: 跑全量前端测试并比对错误数**
|
||
|
||
Run: `cd frontend && npx vitest run 2>&1 | tail -5`
|
||
Expected: 错误数不高于改动前基线（干净 master 为 172 errors、退出码 1，**以错误条数为准，不要以退出码判断**）
|
||
|
||
- [ ] **Step 6: Commit**
|
||
|
||
```bash
|
||
git add frontend/src/views/Materials.vue frontend/src/views/Materials.test.js
|
||
git commit -m "feat: 物料页面接入批量导入与模板下载"
|
||
```
|

|
||
|
||
## Task 10: 文档与端到端验证
|
||
|
||
**Files:**
|
||
|
||
- Modify: `docs/api.md`
|
||
|
||
- [ ] **Step 1: 补接口文档**
|
||
|
||
在 `docs/api.md` 的「图片上传」一行之后新增一行分组说明：
|
||
|
||
```markdown
|
||
| 物料批量导入 | `GET /material-import/template`、`POST /material-import` | 需登录 |
|
||
```
|
||
|
||
并在「## 1. 物料接口」章节末尾（`POST /materials/:id/restore` 之后）补完整接口说明：请求方式、模板列定义、5MB/20000 行限制、成功与失败响应示例、`row` 为 Excel 真实行号、首版仅新增、任意一行失败整批不入库。
|
||
|
||
- [ ] **Step 2: 端到端验证（真实服务 + 真实库）**
|
||
|
||
```bash
|
||
docker compose down -v && docker compose up -d --build
|
||
```
|
||
|
||
然后在 `frontend/` 下 `npm run build` 并重建镜像（**静态文件打进镜像，跑本地 dev/build 看不到效果；nginx 的 immutable 缓存要求浏览器硬刷新**）。
|
||
|
||
- [ ] **Step 3: 手工验证清单**
|
||
|
||
| 场景 | 期望 |
|
||
| ------------------------- | -------------------------------------------- |
|
||
| 下载模板 | 得到 xlsx，含「填写说明」「物料数据」两张表，表头 5 列 |
|
||
| 上传模板原样（无数据） | 提示没有数据行（0 行），不写记录或写 0 行记录 |
|
||
| 上传 2 行合法数据 | 201，列表出现 2 条物料，编码为 `小类前缀+序号`，日志页有 2 条 CREATE |
|
||
| 上传含空名称、错误大类、错误单位、无规则小类的文件 | 400，逐行错误行号与 Excel 一致，列表**没有**新增任何物料 |
|
||
| 上传同名同规格的重复文件两次 | 第二次仍成功（编码不同），确认首版不做重复检测 |
|
||
| 上传 .xls / .csv / 6MB 文件 | 400，提示格式或大小 |
|
||
| 非本公司分类名 | 400，提示分类不存在 |
|
||
| 导入过程中切公司 | 被保存互斥拦住 |
|
||
|
||
- [ ] **Step 4: 确认导入记录落库**
|
||
|
||
Run: `docker compose exec db mysql -uroot -pwmms1234 wmms -e "SELECT organization_id,operator,file_name,total_rows,success_rows,failed_rows,status,failure_reason,created_at FROM material_import_logs ORDER BY id DESC LIMIT 5"`
|
||
Expected: 每次导入（成功与失败）各一条
|
||
|
||
- [ ] **Step 5: 确认回滚确实生效**
|
||
|
||
上传一个"前 199 行合法、第 200 行非法"的文件，然后：
|
||
|
||
Run: `docker compose exec db mysql -uroot -pwmms1234 wmms -e "SELECT COUNT(*) FROM materials WHERE material_code LIKE 'A01%'"`
|
||
Expected: 数量与导入前一致（整批未落库）
|
||
|
||
- [ ] **Step 6: 提交文档**
|
||
|
||
```bash
|
||
git add docs/api.md
|
||
git commit -m "docs: 补充物料批量导入接口说明"
|
||
```
|
||
|
||
---
|
||
|
||
## 已知取舍
|
||
|
||
- **不做重复检测**：同一份文件里两行相同物料都会成功入库，同一份文件重复上传也会导入两遍（编码都不同）。用户故事 BAT-001 提到的「疑似重复物料」不在首版范围。
|
||
- **没有服务端幂等键**：设计原文的「任务 ID 防重复提交」随预览环节一起取消，改为纯前端约束，见「设计约定 8」。
|
||
- **错误明细不落库**：只随响应返回，前端用 CSV 导出。因此历史导入记录里只有汇总原因，翻不回逐行明细。
|
||
- **不使用 `material_types`、`material_unit_conversions`**：与现有单条新增保持一致。
|
||
- **不引入消息队列**：20000 行同步处理，前端超时沿用 axios 默认 30 秒；若实测慢，后续再谈异步。
|
||
- **`material_import_logs` 只写汇总**：第 8 点的「执行状态」只有 `success` / `failed` 两态，没有中间态。
