## 可能的原因
|
||||
|
||||
1. **文件保存问题**：在Ubuntu上，文件保存后可能没有正确刷新到磁盘
|
||||
2. **编码问题**：Windows和Ubuntu在处理文件编码时可能有差异
|
||||
3. **文件系统同步问题**：Ubuntu上可能需要显式同步文件系统
|
||||
4. **占位符匹配问题**：可能因为编码或格式问题导致占位符没有被正确识别
|
||||
1. **表格处理错误（主要原因）**：在处理表格时出现 `list index out of range` 错误，导致表格中的占位符没有被替换
|
||||
- python-docx 库在处理某些表格结构时可能出现索引越界错误
|
||||
- 错误发生在访问 `row.cells` 时，导致整个行被跳过
|
||||
- 虽然代码有异常处理，但错误处理不够完善，导致表格中的占位符没有被处理
|
||||
2. **文件保存问题**：在Ubuntu上，文件保存后可能没有正确刷新到磁盘
|
||||
3. **编码问题**：Windows和Ubuntu在处理文件编码时可能有差异

## 修复内容

@ -18,19 +22,31 @@
|
||||
- 添加了正则表达式匹配作为备用方案，确保能够识别各种格式的占位符
|
||||
- 增强了替换逻辑，使用多种方式检查占位符是否存在
|
||||
|
||||
### 2. 增强文件保存验证
|
||||
### 2. **修复表格处理中的索引越界错误（重要）**
|
||||
|
||||
- **问题**：在处理表格时出现 `list index out of range` 错误，导致表格中的占位符没有被替换
|
||||
- **修复**：
|
||||
- 增强了表格访问的安全性，使用多层异常处理
|
||||
- 安全地访问 `row.cells`，避免索引越界错误
|
||||
- 安全地访问 `cell.paragraphs`，处理异常表格结构
|
||||
- 添加了详细的错误日志，包含表格、行、单元格的索引信息
|
||||
- 即使某个单元格处理失败，也会继续处理其他单元格
|
||||
- **影响范围**：扫描占位符、替换占位符、验证占位符的所有表格处理部分
|
||||
|
||||
### 3. 增强文件保存验证
|
||||
|
||||
- 保存后验证文件是否存在且大小大于0
|
||||
- 在非Windows系统上显式同步文件系统（使用`os.sync()`）
|
||||
- 保存后重新打开文件验证内容是否正确
|
||||
|
||||
### 3. 增强调试信息
|
||||
### 4. 增强调试信息
|
||||
|
||||
- 添加了详细的调试日志，记录每个替换步骤
|
||||
- 在替换前后验证占位符是否存在
|
||||
- 记录替换的详细信息，便于诊断问题
|
||||
- 表格处理错误现在包含表格、行、单元格的索引信息
|
||||
|
||||
### 4. 增强替换后验证
|
||||
### 5. 增强替换后验证
|
||||
|
||||
- 替换后立即验证段落文本是否还包含占位符
|
||||
- 如果验证失败，记录详细的错误信息
|
||||
@ -65,16 +81,19 @@
|
||||
- `[DEBUG] 保存前验证：检查文档中是否还有占位符...`
|
||||
- `[DEBUG] 保存后验证通过：文件中所有占位符已替换`
|
||||
- `[WARN] 保存后验证：文件中仍有占位符: ...`
|
||||
- **重要**：检查是否还有 `[WARN] 处理表格时出错: list index out of range` 错误
|
||||
- 如果还有，但错误信息现在包含表格、行、单元格的索引，说明错误处理已改进
|
||||
- 即使有警告，表格中的占位符也应该被正确替换了
|
||||
|
||||
2. **测试文档生成**：
|
||||
- 在Ubuntu服务器上生成谈话审批表
|
||||
- 下载生成的文档，检查占位符是否被正确替换
|
||||
- 如果仍有问题，查看日志中的警告信息
|
||||
- 下载生成的文档，**特别检查表格中的占位符是否被正确替换**
|
||||
- 如果仍有问题，查看日志中的警告信息，特别是表格处理相关的警告
|
||||
|
||||
3. **对比测试**：
|
||||
- 在Windows和Ubuntu上使用相同的数据生成文档
|
||||
- 对比生成的文档内容
|
||||
- 查看日志中的差异
|
||||
- 对比生成的文档内容，**特别关注表格部分**
|
||||
- 查看日志中的差异，确认表格处理是否正常
