📋 Pending Tasks

Models (Priority: Critical)

Need to copy and adapt from v1 with improvements:

1. User Model - Add indexes on username
2. Player Model - Add indexes on auth_code, group_id, last_seen
3. Group Model - Add indexes on name
4. Content Model - Add indexes on content_type, position, uploaded_at
5. ServerLog Model - Add indexes on level, timestamp
6. PlayerFeedback Model - Add indexes on player_id, timestamp
7. Association Tables - group_content for many-to-many relationship

Utils (Priority: Critical)

Need to copy and adapt from v1 with type hints:

1. logger.py - Logging utility with type hints
2. uploads.py - File upload utilities with progress tracking
3. group_player_management.py - Group/player management functions
4. pptx_converter.py - PowerPoint conversion utility

Templates (Priority: High)

Need to copy from v1 and update route references:

1. Update all url_for() calls to use blueprint naming:

   • url_for('login') → url_for('auth.login')
   • url_for('dashboard') → url_for('main.dashboard')
   • url_for('add_player') → url_for('players.add_player')
   • etc.

2. Organize templates into subdirectories:

   • auth/ - login.html, register.html
   • admin/ - admin.html
   • players/ - players_list.html, add_player.html, edit_player.html, player_page.html, player_fullscreen.html
   • groups/ - groups_list.html, create_group.html, edit_group.html, manage_group.html, group_fullscreen.html
   • content/ - content_list.html, upload_content.html, edit_content.html
   • errors/ - 404.html, 403.html, 500.html
   • base.html - Main layout template

Docker Configuration (Priority: High)

1. Dockerfile - Multi-stage build targeting 800MB
2. docker-compose.yml - Services: digiserver, redis, optional worker
3. nginx.conf - Reverse proxy configuration
4. .dockerignore - Docker ignore patterns

Testing (Priority: Medium)

1. tests/conftest.py - Test fixtures
2. tests/test_auth.py - Authentication tests
3. tests/test_players.py - Player management tests
4. tests/test_groups.py - Group management tests
5. tests/test_content.py - Content management tests
6. tests/test_api.py - API endpoint tests

Git Repository (Priority: Medium)

1. Initialize Git repository
2. Create initial commit
3. Push to remote (if desired)

🎯 Next Steps

Immediate Actions

1. Copy models from v1 - Add to app/models/ with:

   • Type hints
   • Database indexes
   • Proper relationships
   • __repr__ methods

2. Copy utils from v1 - Add to app/utils/ with:

   • Type hints
   • Improved error handling
   • Documentation

3. Create model init file - app/models/__init__.py to export all models

After Models/Utils

4. Copy templates from v1 - Update route references to blueprint naming
5. Create Docker configuration - Multi-stage build with optimization
6. Test application - Ensure all routes work correctly
7. Initialize Git - Create repository and initial commit

📝 Notes

Architecture Decisions

• Blueprint organization: Logical separation by functionality
• Caching strategy: Redis for production, SimpleCache for development
• Authentication: Flask-Login for web, Bearer tokens for API
• Rate limiting: In-memory for now, should use Redis in production
• File uploads: Direct save with progress tracking, can add Celery for async processing

Optimization Opportunities

• Add Celery for async video processing
• Implement WebSocket for real-time player updates
• Add comprehensive database migrations
• Implement API versioning (v1, v2)
• Add comprehensive test coverage
• Add Sentry for error tracking

Migration from v1

When copying from v1, remember to:

• Update all route references to blueprint naming
• Add type hints to all functions
• Add database indexes for performance
• Update imports to match new structure
• Update static file paths in templates
• Test all functionality thoroughly

🚀 Ready for Next Phase

The blueprint architecture is now fully implemented with all 6 blueprints:

• ✅ main (dashboard, health)
• ✅ auth (login, register, logout)
• ✅ admin (user management, system settings)
• ✅ players (CRUD, fullscreen, bulk ops)
• ✅ groups (CRUD, manage, fullscreen)
• ✅ content (upload, manage, API)
• ✅ api (REST endpoints, authentication, rate limiting)

Ready to proceed with models and utils migration!
