| 智能填表 | `template_fill_service.py` `fill_template()` | 使用 LLM 从源文档提取信息 |
|
||||
| 结果导出 | `templates.py` `/templates/export` | 导出为 Excel 或 Word |
|
||||
|
||||
### 8.2 源文档加载方式
|
||||
|
||||
模板填表服务支持两种方式加载源文档:
|
||||
|
||||
1. **通过 MongoDB 文档 ID**:`source_doc_ids`
|
||||
- 文档已上传并存入 MongoDB
|
||||
- 服务直接查询 MongoDB 获取文档内容
|
||||
|
||||
2. **通过文件路径**:`source_file_paths`
|
||||
- 直接读取本地文件
|
||||
- 使用对应的解析器解析内容
|
||||
|
||||
### 8.3 Word 表格模板解析
|
||||
|
||||
比赛评分表格通常是 Word 格式,`docx_parser.py` 提供了专门的解析方法:
|
||||
|
||||
```python
|
||||
# 提取表格模板字段
|
||||
fields = docx_parser.extract_template_fields_from_docx(file_path)
|
||||
|
||||
# 返回格式
|
||||
# [
|
||||
# {
|
||||
# "cell": "T0R1", # 表格0,行1
|
||||
# "name": "字段名",
|
||||
# "hint": "提示词",
|
||||
# "field_type": "text/number/date",
|
||||
# "required": True
|
||||
# },
|
||||
# ...
|
||||
# ]
|
||||
```
|
||||
|
||||
### 8.4 字段类型推断
|
||||
|
||||
系统支持从提示词自动推断字段类型:
|
||||
|
||||
| 关键词 | 推断类型 | 示例 |
|
||||
|--------|----------|------|
|
||||
| 年、月、日、日期、时间、出生 | date | 出生日期 |
|
||||
| 数量、金额、比率、%、率、合计 | number | 增长比率 |
|
||||
| 其他 | text | 姓名、地址 |
|
||||
|
||||
