 # Article Writer - 文章编写系统

-基于 Flask + LLM 的智能文章编写系统，支持主题管理、素材收集和大模型生成文章。
+基于 Flask + LLM 的智能文章编写系统，支持主题管理、素材收集、分类标签和大模型生成文章。

 ## 功能

 - 主题管理：创建、编辑、删除文章主题
- 素材收集：支持文本素材和图片素材
- Prompt编辑：每个主题可自定义生成提示词
+- 分类系统：多级分类，每个主题可归属多个分类
+- 标签系统：灵活标签，每个主题支持多个标签，支持新建标签
+- 素材收集：支持文本素材和图片素材（含Ctrl+V粘贴截图）
+- Prompt编辑：每个主题可自定义生成提示词，支持历史记录
 - 大模型生成：调用 LLM 根据素材自动生成文章
- 文章管理：查看、编辑、删除生成的文章
+- 文章管理：查看、编辑、删除、复制、下载生成的文章

 ## 技术栈

 - 后端：Python 3 + Flask + SQLite
- 前端：HTML/CSS/JS（原生）
+- 前端：HTML/CSS/JS（Bootstrap 5 暗色主题）
 - LLM：兼容 OpenAI API 格式的大模型接口

+## 数据结构
+
+- **topics** - 文章主题
+- **categories** - 分类（支持多对多关联）
+- **tags** - 标签（支持多对多关联，自动清理孤立标签）
+- **topic_categories** - 主题-分类关联表
+- **topic_tags** - 主题-标签关联表
+- **materials** - 素材（文本/图片）
+- **articles** - 生成的文章

+- `POST /api/categories` - 创建分类
+- `PUT /api/categories/<id>` - 更新分类
+- `DELETE /api/categories/<id>` - 删除分类
+
+### 标签
+- `GET /api/tags` - 标签列表（含主题计数）
+- `POST /api/tags` - 创建标签
+- `DELETE /api/tags/<id>` - 删除标签
+
+### 主题
+- `POST /api/topics` - 创建主题（支持 category_ids, tag_ids, new_tags）
+- `PUT /api/topics/<id>` - 更新主题（支持更新分类和标签关联）
