+# 提示词模版选择功能实现总结
+
+## 功能概述
+实现了用户在创建会议时可以选择使用的总结模版功能。支持两种场景：
+1. 手动生成会议总结时选择模版
+2. 上传音频文件时选择模版，自动总结时使用该模版
+
+## 实现的功能点
+
+### 1. 新增API接口 ✅
+**文件**: `app/api/endpoints/prompts.py`
+- 新增 `GET /prompts/active/{task_type}` 接口
+- 功能：获取指定任务类型的所有启用状态的提示词模版
+- 返回字段：id, name, is_default
+- 按默认模版优先、创建时间倒序排列
+
+### 2. 修改LLM服务 ✅
+**文件**: `app/services/llm_service.py`
+- 修改 `get_task_prompt()` 方法，增加 `prompt_id` 可选参数
+- 逻辑：
+  - 如果指定 prompt_id，查询该ID对应的提示词（需验证task_type和is_active）
+  - 如果不指定，使用默认提示词（is_default=TRUE）
+  - 如果都查不到，返回代码中的默认值
+
+### 3. 修改会议总结服务 ✅
+**文件**: `app/services/async_meeting_service.py`
+
+#### 3.1 修改任务创建
+- `start_summary_generation()`: 增加 `prompt_id` 参数
+- 将 prompt_id 存储到 Redis 和数据库
+
+#### 3.2 修改任务处理
+- `_process_task()`: 从 Redis 读取 prompt_id，传递给 `_build_prompt()`
+- `_build_prompt()`: 增加 `prompt_id` 参数，传递给 `llm_service.get_task_prompt()`
+- `_save_task_to_db()`: 增加 `prompt_id` 参数，存储到数据库
+
+#### 3.3 修改自动总结监控
+- `monitor_and_auto_summarize()`: 增加 `prompt_id` 参数
+- 在转录完成后启动总结任务时，传递 prompt_id
+
+### 4. 修改音频服务 ✅
+**文件**: `app/services/audio_service.py`
+- `handle_audio_upload()`: 增加 `prompt_id` 参数
+- 将 prompt_id 传递给 `monitor_and_auto_summarize()`
+
+### 5. 修改会议API接口 ✅
+**文件**: `app/api/endpoints/meetings.py`
+
+#### 5.1 手动生成总结
+- `GenerateSummaryRequest` 模型：增加 `prompt_id` 字段
+- `POST /meetings/{meeting_id}/generate-summary-async`: 传递 prompt_id 给服务层
+
+#### 5.2 音频上传
+- `POST /meetings/upload-audio`: 增加 `prompt_id` 表单参数
+- 将 prompt_id 传递给 `handle_audio_upload()`
+
+### 6. 数据库迁移 ✅
+**文件**: `sql/add_prompt_id_to_llm_tasks.sql`
+- 为 `llm_tasks` 表添加 `prompt_id` 列
+- 类型：int(11)
+- 可空：YES
+- 默认值：NULL
+- 索引：idx_prompt_id
+
+## 数据流向
+
+### 手动生成总结
+```
+前端 → POST /meetings/{id}/generate-summary-async (prompt_id)
+     → async_meeting_service.start_summary_generation(prompt_id)
+     → 存储到 Redis 和 DB (llm_tasks.prompt_id)
+     → _process_task() 读取 prompt_id
+     → _build_prompt(prompt_id)
+     → llm_service.get_task_prompt('MEETING_TASK', prompt_id)
+     → 获取指定模版或默认模版
+```
+
+### 音频上传自动总结
+```
+前端 → POST /meetings/upload-audio (prompt_id, auto_summarize=true)
+     → handle_audio_upload(prompt_id)
+     → transcription_service.start_transcription()
+     → monitor_and_auto_summarize(prompt_id)
+     → 等待转录完成
+     → start_summary_generation(prompt_id)
+     → （后续流程同手动生成总结）
+```
+
+## 向后兼容性
+
+所有新增的 `prompt_id` 参数都是可选的（Optional[int] = None），确保：
+1. 不传递 prompt_id 时，自动使用默认模版
+2. 现有代码无需修改即可正常工作
+3. 数据库中 prompt_id 允许为 NULL
+
+## 测试结果
+
+执行 `test_prompt_id_feature.py` 测试脚本，所有测试通过：
+- ✅ 获取启用的提示词列表 (6个模版)
+- ✅ 通过prompt_id获取提示词内容
+- ✅ 获取默认提示词（不指定prompt_id）
+- ✅ 验证方法签名支持prompt_id参数
+- ✅ 验证数据库schema包含prompt_id列
+- ✅ 验证API端点定义正确
+
+## 使用示例
+
+### 1. 获取启用的会议任务模版列表
+```bash
+GET /api/prompts/active/MEETING_TASK
+Authorization: Bearer <token>
+```
+
+返回：
+```json
+{
+  "code": "200",
+  "message": "获取启用模版列表成功",
+  "data": {
+    "prompts": [
+      {"id": 1, "name": "默认会议总结", "is_default": true},
+      {"id": 5, "name": "产品会议总结", "is_default": false}
+    ]
+  }
+}
+```
+
+### 2. 手动生成总结时指定模版
+```bash
+POST /api/meetings/123/generate-summary-async
+Authorization: Bearer <token>
+Content-Type: application/json
+
+{
+  "user_prompt": "重点关注技术讨论",
+  "prompt_id": 5
+}
+```
+
+### 3. 上传音频时指定模版
+```bash
+POST /api/meetings/upload-audio
+Authorization: Bearer <token>
+Content-Type: multipart/form-data
+
+- audio_file: <file>
+- meeting_id: 123
+- auto_summarize: true
+- prompt_id: 5
+```
+
+## 文件变更列表
+
+1. `app/api/endpoints/prompts.py` - 新增API接口
+2. `app/api/endpoints/meetings.py` - 修改两个端点
+3. `app/services/llm_service.py` - 修改get_task_prompt方法
+4. `app/services/async_meeting_service.py` - 修改4个方法
+5. `app/services/audio_service.py` - 修改handle_audio_upload方法
+6. `sql/add_prompt_id_to_llm_tasks.sql` - 数据库迁移脚本
+7. `test_prompt_id_feature.py` - 测试脚本
+
+## 注意事项
+
+1. prompt_id 会与 task_type 一起验证，防止使用错误类型的模版
+2. 如果指定的 prompt_id 不存在或未启用，会自动使用默认模版
+3. 历史任务记录保留 prompt_id，即使对应的提示词被删除
+4. Redis 中 prompt_id 存储为字符串，使用时需转换为 int

+     → llm_service.get_task_prompt('KNOWLEDGE_TASK', prompt_id)
+     → 获取指定模版或默认模版
+```
+
+## 向后兼容性
+
+所有新增的 `prompt_id` 参数都是可选的（Optional[int] = None），确保：
+1. 不传递 prompt_id 时，自动使用默认模版
+2. 现有代码无需修改即可正常工作
+3. 数据库中 prompt_id 有默认值 0
+
+## 测试结果
+
+执行 `test_kb_prompt_id_feature.py` 测试脚本，所有测试通过：
+- ✅ 获取启用的知识库提示词列表 (3个模版)
+- ✅ 通过prompt_id获取提示词内容
+- ✅ 获取默认提示词（不指定prompt_id）
+- ✅ 验证方法签名支持prompt_id参数
+- ✅ 验证数据库schema包含prompt_id列
+- ✅ 验证API模型定义正确
+
+## 使用示例
+
+### 1. 获取启用的知识库任务模版列表
+```bash
+GET /api/prompts/active/KNOWLEDGE_TASK
+Authorization: Bearer <token>
+```
+
+返回：
+```json
+{
+  "code": "200",
+  "message": "获取启用模版列表成功",
+  "data": {
+    "prompts": [
+      {"id": 2, "name": "默认知识库生成", "is_default": true},
+      {"id": 13, "name": "分析总结模版", "is_default": false}
+    ]
+  }
+}
+```
+
+### 2. 创建知识库时指定模版
+```bash
+POST /api/knowledge-bases
+Authorization: Bearer <token>
+Content-Type: application/json
+
+{
+  "title": "产品会议知识库",
+  "is_shared": false,
+  "user_prompt": "重点提取产品功能相关信息",
+  "source_meeting_ids": "1,2,3",
+  "tags": "产品,功能",
+  "prompt_id": 13
+}
+```
+
+## 文件变更列表
+
+1. `app/models/models.py` - 修改CreateKnowledgeBaseRequest模型
+2. `app/services/async_knowledge_base_service.py` - 修改5个方法
+3. `app/api/endpoints/knowledge_base.py` - 修改create_knowledge_base端点
+4. `test_kb_prompt_id_feature.py` - 测试脚本
+
+## 与会议总结功能的一致性
+
+知识库的实现与会议总结功能保持一致：
+- 相同的prompt_id传递机制
+- 相同的Redis存储格式（字符串）
+- 相同的数据库字段类型
+- 相同的向后兼容策略
+- 相同的验证逻辑（task_type + is_active）
+
+## 注意事项
+
+1. prompt_id 会与 task_type='KNOWLEDGE_TASK' 一起验证
+2. 如果指定的 prompt_id 不存在或未启用，会自动使用默认模版
+3. 历史任务记录保留 prompt_id，即使对应的提示词被删除
+4. Redis 中 prompt_id 存储为字符串，使用时需转换为 int
+5. 数据库 prompt_id 默认值为 0（表示未指定）
+
+## 总结
+
+知识库提示词模版选择功能已完全实现并通过测试，与会议总结功能保持一致的设计和实现方式。用户现在可以在创建知识库时选择不同的生成模版，以满足不同场景的需求。

+# 客户端管理 - 专用终端类型添加说明
+
+## 概述
+
+本次更新在客户端管理系统中添加了"专用终端"（terminal）大类型，支持 Android 专用终端和单片机（MCU）平台。
+
+## 数据库变更
+
+### 1. 修改表结构
+
+执行 SQL 文件：`add_dedicated_terminal.sql`
+
+```bash
+mysql -u [username] -p [database_name] < backend/sql/add_dedicated_terminal.sql
+```
+
+**变更内容：**
+- 修改 `client_downloads` 表的 `platform_type` 枚举，添加 `terminal` 类型
+- 插入两条示例数据：
+  - Android 专用终端（platform_type: `terminal`, platform_name: `android`）
+  - 单片机固件（platform_type: `terminal`, platform_name: `mcu`）
+
+### 2. 新的平台类型
+
+| platform_type | platform_name | 说明 |
+|--------------|--------------|------|
+| terminal | android | Android 专用终端 |
+| terminal | mcu | 单片机（MCU）固件 |
+
+## API 接口变更
+
+### 1. 新增接口：通过平台类型和平台名称获取最新版本
+
+**接口路径：** `GET /api/downloads/latest/by-platform`
+
+**请求参数：**
+- `platform_type` (string, required): 平台类型 (mobile, desktop, terminal)
+- `platform_name` (string, required): 具体平台名称
+
+**示例请求：**
+```bash
+# 获取 Android 专用终端最新版本
+curl "http://localhost:8000/api/downloads/latest/by-platform?platform_type=terminal&platform_name=android"
+
+# 获取单片机固件最新版本
+curl "http://localhost:8000/api/downloads/latest/by-platform?platform_type=terminal&platform_name=mcu"
+```
+
+**返回示例：**
+```json
+{
+  "code": "200",
+  "message": "获取成功",
+  "data": {
+    "id": 7,
+    "platform_type": "terminal",
+    "platform_name": "android",
+    "version": "1.0.0",
+    "version_code": 1000,
+    "download_url": "https://download.imeeting.com/terminals/android/iMeeting-Terminal-1.0.0.apk",
+    "file_size": 25165824,
+    "release_notes": "专用终端初始版本\n- 支持专用硬件集成\n- 优化的录音功能\n- 低功耗模式\n- 自动上传同步",
+    "is_active": true,
+    "is_latest": true,
+    "min_system_version": "Android 5.0",
+    "created_at": "2025-01-15T10:00:00",
+    "updated_at": "2025-01-15T10:00:00",
+    "created_by": 1
+  }
+}
+```
+
+### 2. 更新接口：获取所有平台最新版本
+
+**接口路径：** `GET /api/downloads/latest`
+
+**变更：** 返回数据中新增 `terminal` 字段
+
+**返回示例：**
+```json
+{
+  "code": "200",
+  "message": "获取成功",
+  "data": {
+    "mobile": [...],
+    "desktop": [...],
+    "terminal": [
+      {
+        "id": 7,
+        "platform_type": "terminal",
+        "platform_name": "android",
+        "version": "1.0.0",
+        ...
+      },
+      {
+        "id": 8,
+        "platform_type": "terminal",
+        "platform_name": "mcu",
+        "version": "1.0.0",
+        ...
+      }
+    ]
+  }
+}
+```
+
+### 3. 已有接口说明
+
+**原有接口：** `GET /api/downloads/{platform_name}/latest`
+
+- 此接口标记为【已废弃】，建议使用新接口 `/downloads/latest/by-platform`
+- 原因：只通过 `platform_name` 查询可能产生歧义（如 mobile 的 android 和 terminal 的 android）
+- 保留此接口是为了向后兼容，但新开发应使用新接口
+
+## 使用场景
+
+### 场景 1：专用终端设备版本检查
+
+专用终端设备（如会议室固定录音设备、单片机硬件）启动时检查更新：
+
+```javascript
+// Android 专用终端
+const response = await fetch(
+  '/api/downloads/latest/by-platform?platform_type=terminal&platform_name=android'
+);
+const { data } = await response.json();
+
+if (data.version_code > currentVersionCode) {
+  // 发现新版本，提示更新
+  showUpdateDialog(data);
+}
+```
+
+### 场景 2：后台管理界面展示
+
+管理员查看所有终端版本：
+
+```javascript
+const response = await fetch('/api/downloads?platform_type=terminal');
+const { data } = await response.json();
+
+// data.clients 包含所有 terminal 类型的客户端版本
+renderClientList(data.clients);
+```
+
+### 场景 3：固件更新服务器
+
+单片机设备定期轮询更新：
+
+```c
+// MCU 固件代码示例
+char url[] = "http://api.imeeting.com/downloads/latest/by-platform?platform_type=terminal&platform_name=mcu";
+http_get(url, response_buffer);
+
+// 解析 JSON 获取 download_url 和 version_code
+if (new_version > FIRMWARE_VERSION) {
+    download_and_update(download_url);
+}
+```
+
+## 测试建议
+
+### 1. 数据库测试
+```sql
+-- 验证表结构修改
+DESCRIBE client_downloads;
+
+-- 验证数据插入
+SELECT * FROM client_downloads WHERE platform_type = 'terminal';
+```
+
+### 2. API 测试
+```bash
+# 测试新接口
+curl "http://localhost:8000/api/downloads/latest/by-platform?platform_type=terminal&platform_name=android"
+
+curl "http://localhost:8000/api/downloads/latest/by-platform?platform_type=terminal&platform_name=mcu"

+
+## 注意事项
+
+1. **执行 SQL 前请备份数据库**
+2. **ENUM 类型修改**：ALTER TABLE 会修改表结构，请在低峰期执行
+3. **新接口优先**：建议所有新开发使用 `/downloads/latest/by-platform` 接口
+4. **版本管理**：上传新版本时记得设置 `is_latest=TRUE` 并将同平台旧版本设为 `FALSE`
+5. **platform_name 唯一性**：如果 mobile 和 terminal 都有 android，建议：
+   - mobile 的保持 `android`
+   - terminal 的改为 `android_terminal` 或其他区分名称
+   - 或者始终使用新接口同时传递 platform_type 和 platform_name
