Auto-Import Implementation Summary

What was implemented:

1. Dependencies (pyproject.toml)

• Created pyproject.toml in quiz/ directory
• Added Django and watchdog dependencies
• Configured for uv package manager

2. Question Importer (quiz/utils/importer.py)

• ImportStats class: Tracks import statistics including:
  • Total files found
  • MCQ vs non-MCQ questions
  • Questions with answers vs TODO placeholders
  • Created vs updated counts
  • Per-folder completion statistics
• parse_markdown_question(): Parses markdown files to extract:
  • Question text
  • Options (supports both - A: and - A formats)
  • Correct answer from spoiler blocks
  • Skips questions with "TODO" answers
• import_question_file(): Imports a single question file
• import_questions(): Bulk import with statistics
• delete_question_by_path(): Removes deleted questions from database

3. File System Watcher (quiz/utils/watcher.py)

• QuestionFileHandler: Handles file system events with:
  • 2-second debounce for file changes
  • Auto-import on file create/modify
  • Auto-delete on file removal
  • Real-time console feedback
• QuestionWatcher: Main watcher class using watchdog Observer
• start_watcher_thread(): Starts watcher in background daemon thread
  • Performs initial full import on startup
  • Displays comprehensive statistics
  • Continues watching for changes

4. Django Integration

• Updated QuizAppConfig.ready() in apps.py:
  • Automatically starts watcher thread on Django startup
  • Runs in daemon thread (doesn't block shutdown)
  • Only runs in main process (not reloader)
• Updated import_questions management command:
  • Uses refactored importer
  • Shows detailed statistics output
• Added QUESTION_WATCH_PATH setting to settings.py

Current Statistics:

Total .md files found:     312
MCQ questions found:       162
Non-MCQ skipped:           152
Questions with answers:    6
Questions with TODO:       154
Overall completion:        3.7%

Completion by Exam Folder:
2022-01-15             2/ 25 MCQ (  8.0%)
2022-06-01             4/ 19 MCQ ( 21.1%)
2023-01-11             0/ 17 MCQ (  0.0%)
2023-05-31             0/ 10 MCQ (  0.0%)
2024-01-10             0/ 14 MCQ (  0.0%)
2024-05-29             0/ 14 MCQ (  0.0%)
2025-01-15             0/ 16 MCQ (  0.0%)
2025-02-08             0/ 16 MCQ (  0.0%)
2025-06-03             0/ 16 MCQ (  0.0%)
2025-08-08             0/ 15 MCQ (  0.0%)

How it works:

1. On Django startup:

   • Background thread starts automatically
   • Performs initial import of all questions
   • Displays comprehensive statistics
   • Begins watching for file changes

2. When you edit a question in Obsidian:

   • Watcher detects file change
   • Waits 2 seconds (debounce multiple saves)
   • Automatically imports/updates the question
   • Shows console feedback

3. When you delete a question file:

   • Watcher detects deletion
   • Removes question from database

4. Manual import:

   • Run: python3 manage.py import_questions
   • Shows same detailed statistics

Future considerations:

Multi-select questions support:

Currently the Question.correct_answer field is max_length=1, which only supports single answers. Many questions have "Välj två alternativ" and answers like "B och D" or "B, D".

To support multi-select:

1. Update Question.correct_answer to max_length=50
2. Create Django migration
3. Update parse_markdown_question() to extract multiple letters (e.g., "B och D" → "B,D")
4. Update views.py answer validation to compare sorted comma-separated values
5. Update quiz UI to allow selecting multiple options

Answer format normalization:

Need to standardize multi-select answer format in Obsidian:

• Current: "B och D", "B, D", "BD"
• Recommended: "B,D" (sorted, comma-separated, no spaces)

Question types not yet supported:

• frågetyp/hotspot: Image-based clickable questions
• frågetyp/dnd-text: Drag-and-drop text matching
• frågetyp/textfält: Free text input questions
• frågetyp/sammansatt: Multi-part questions

These are currently skipped during import.

Testing the implementation:

1. Start Django server:

   cd /Users/johandahlin/dev/medical-notes/quiz
   python3 manage.py runserver
   

   You'll see the initial import statistics on startup.

2. Test auto-import:

   • Open a question in Obsidian with "TODO" in spoiler block
   • Replace "TODO" with a letter (e.g., "B")
   • Save the file
   • Check Django console for auto-import message

3. Test manual import:

   python3 manage.py import_questions
   

4. Check database:

   python3 manage.py shell
   >>> from quiz.models import Question
   >>> Question.objects.count()
