# Legacy Playlist Routes & Templates

## Status: DEPRECATED ❌

The `playlist/` folder contains legacy code that has been superseded by the content management interface.

## What Changed

### Old Workflow (DEPRECATED)
- Route: `/playlist/<player_id>` 
- Template: `playlist/manage_playlist.html`
- Used for managing playlists at the player level

### New Workflow (ACTIVE) ✅
- Route: `/content/playlist/<playlist_id>/manage`
- Template: `content/manage_playlist_content.html`
- Used for managing playlists in the content area
- Accessed from: Players → Manage Player → "Edit Playlist Content" button

## Migration Notes

**January 17, 2026:**
- Moved `app/templates/playlist/` to `old_code_documentation/playlist/`
- Updated `/playlist/<player_id>` route to redirect to the new content management interface
- All playlist operations now go through the content management area (`manage_playlist_content.html`)

## Why the Change?

1. **Unified Interface**: Single playlist management interface instead of duplicate functionality
2. **Better UX**: Content management area is the primary interface accessed from players
3. **Maintenance**: Reduces code duplication and maintenance burden

## Routes Still in Code

The routes in `app/blueprints/playlist.py` still exist but are now legacy:
- `@playlist_bp.route('/<int:player_id>')` - Redirects to content management
- `@playlist_bp.route('/<int:player_id>/add')` - No longer used
- `@playlist_bp.route('/<int:player_id>/remove/<int:content_id>')` - No longer used
- etc.

These can be removed in a future cleanup if needed.

## Features in New Interface

The new `manage_playlist_content.html` includes all features plus:
- ✅ Drag-to-reorder functionality
- ✅ Duration spinner buttons (⬆️ ⬇️)
- ✅ Audio on/off toggle
- ✅ Edit mode toggle for PDFs/images
- ✅ Dark mode support
- ✅ Bulk delete with checkboxes
