Fixes Summary: Bilingual File and Message Section Issues

Date: 2025-11-12
Issues Fixed: Bilingual file persistence, Message section content, Content duplication

---

Issues Identified

1. Bilingual file not saved to current directory

   • File was created in temp directory but not copied to current directory
   • File was lost after temp directory cleanup

2. Message section not appearing correctly

   • Bilingual file path wasn't being found correctly
   • Message section was empty or had wrong content

3. Content duplication

   • PDF content was being processed as a document, causing duplication
   • Bilingual file content was mixed with extracted PDF content
   • Same content appeared in multiple sections

4. Qwen2.5 not used in translate_document

   • translate_document() was creating DocumentProcessingAgent without use_qwen_translation=True

---

Fixes Applied

1. Save Bilingual File to Current Directory ✅

File: app.py

Change:

# Copy bilingual file to current directory for persistence and easy access
bilingual_filename = os.path.basename(bilingual_path_temp)
bilingual_path = bilingual_filename  # Save in current directory
shutil.copy2(bilingual_path_temp, bilingual_path)
progress(0.5, desc=f"💾 Saved bilingual translation to {bilingual_filename}...")

Result: Bilingual file is now saved to current directory (e.g., test_sermon_bilingual.txt)

---

2. Use Qwen2.5 in translate_document ✅

File: app.py

Change:

# Initialize processor with Qwen2.5 translation enabled
processor = DocumentProcessingAgent(GEMMA_BACKEND_URL, use_qwen_translation=True)

Result: Translation now uses Qwen2.5 by default

---

3. Prevent PDF and Bilingual File Duplication ✅

File: document_processing_agent.py

Change:

async def process_documents(self, document_paths: List[str]) -> List[DocumentContent]:
    """Process multiple documents and extract structured content"""
    results = []
    
    for doc_path in document_paths:
        # Skip bilingual text files - they're handled separately for Message section
        if doc_path and isinstance(doc_path, str) and doc_path.endswith('_bilingual.txt'):
            continue
        
        # Skip PDF files - they're only used for date extraction, not content extraction
        # PDF content should not be processed as it causes duplication
        if doc_path and isinstance(doc_path, str) and doc_path.lower().endswith('.pdf'):
            continue
        
        # ... process other documents

Result:

• PDF files are skipped during document processing (only used for date extraction)
• Bilingual files are skipped during document processing (handled separately)
• No duplication from PDF or bilingual file content

---

4. Message Section Uses Only Bilingual Content ✅

File: document_processing_agent.py

Change:

# Replace Message section with Bilingual Document Translation
# Load bilingual document and format it - this is the ONLY source for Message section
bilingual_content = self._load_bilingual_document(document_sources)
messages_formatted = "Sermon message to be prepared"

if bilingual_content and bilingual_content.strip():
    # ... format bilingual content ...
    messages_formatted = f"""*Date: {formatted_date}*

{bilingual_text}"""
else:
    # No bilingual document available - use fallback message
    # Don't use aggregated_content.get('messages') to avoid duplication from PDF processing
    messages_formatted = "Sermon message to be prepared"

Result:

• Message section ONLY uses bilingual file content
• No mixing with extracted PDF content
• No duplication

Expected Behavior After Fixes

File Flow

1. DOCX Upload → Extract content
2. Translation → Create {docx_name}_bilingual.txt in temp directory
3. Copy to Current Directory → Save {docx_name}_bilingual.txt to current directory
4. Generate Program → Use bilingual file for Message section, PDF for date only

Message Section Content

• Source: Only from {docx_name}_bilingual.txt
• Format:

  ## Message
  
  *Date: November 9, 2025*
  
  [Chinese paragraph 1]
  [English translation 1]
  
  [Chinese paragraph 2]
  [English translation 2]
  ...
  

No Duplication

• ✅ PDF content not processed as document
• ✅ Bilingual file not processed as document
• ✅ Message section only uses bilingual file
• ✅ No duplicate content in other sections

---

Testing

To verify fixes:

1. Check bilingual file exists:

   ls -la *_bilingual.txt
   

2. Check Message section:

   • Open generated markdown file
   • Verify Message section contains bilingual content
   • Verify no duplication from PDF

3. Check no duplication:

   • Verify content doesn't appear multiple times
   • Verify PDF content not in Message section
   • Verify bilingual content only in Message section

Files Modified

• app.py - Save bilingual file, use Qwen2.5
• document_processing_agent.py - Skip PDF/bilingual processing, Message section fix
