Andika 1988787a1f Template-Based CSV Import System with R2 Storage ...

Solution: Updated backend/r2_storage.py:
  - Added ALLOWED_CSV_TYPES for CSV file validation
  - Added upload_bytes() method for uploading raw bytes to R2
  - Added download_file() method for retrieving files from R2
  - Added delete_multiple() method for bulk file deletion

  Comprehensive upload endpoint now stores CSVs in R2:
  r2_storage = get_r2_storage()
  for file_type, (content, filename) in file_contents.items():
      _, r2_key, _ = await r2_storage.upload_bytes(
          content=content,
          folder=f"imports/{job_id}",
          filename=f"{file_type}_{filename}",
          content_type='text/csv'
      )
      r2_keys[file_type] = r2_key

  3. Fixed JSON Serialization Error

  Problem: Object of type datetime is not JSON serializable when saving import metadata.

  Solution: Added serialize_for_json() helper in backend/server.py:
  def serialize_for_json(obj):
      """Recursively convert datetime objects to ISO strings for JSON serialization."""
      if isinstance(obj, (datetime, date)):
          return obj.isoformat()
      elif isinstance(obj, dict):
          return {k: serialize_for_json(v) for k, v in obj.items()}
      elif isinstance(obj, list):
          return [serialize_for_json(item) for item in obj]
      # ... handles other types

  4. Fixed Route Ordering (401 Unauthorized)

  Problem: /admin/import/comprehensive/upload returned 401 because FastAPI matched "comprehensive" as a {job_id} parameter.

  Solution: Moved comprehensive import routes BEFORE generic {job_id} routes in backend/server.py:
  # Correct order:
  @app.post("/api/admin/import/comprehensive/upload")  # Specific route FIRST
  # ... other comprehensive routes ...

  @app.get("/api/admin/import/{job_id}/preview")  # Generic route AFTER

  5. Improved Date Parsing

  Solution: Added additional date formats to backend/wordpress_parser.py:
  formats = [
      '%m/%d/%Y', '%Y-%m-%d', '%d/%m/%Y', '%B %d, %Y', '%b %d, %Y',
      '%Y-%m-%d %H:%M:%S',
      '%m/%Y',      # Month/Year: 01/2020
      '%m-%Y',      # Month-Year: 01-2020
      '%b-%Y',      # Short month-Year: Jan-2020
      '%B-%Y',      # Full month-Year: January-2020
  ]
