|
|
|
|
## 🔧 Critical Fixes Implemented
|
|
|
|
### 1. Database Persistence Issue ⭐ CRITICAL
|
|
**Problem**: Downloaded playlists lost on container rebuild
|
|
**Root Cause**: SQLite database not in persistent volume
|
|
**Solution**:
|
|
- Created `/app/data` volume mount
|
|
- Updated Django settings to use `/app/data/db.sqlite3`
|
|
- Added proper `.gitignore` for data directory
|
|
|
|
**Files Modified**:
|
|
- `docker-compose.yml` - Added data volume
|
|
- `backend/config/settings.py` - Updated database path
|
|
- Created `data/.gitignore`
|
|
|
|
**Verification**: ✅ Database now persists across `docker-compose down/up`
|
|
|
|
---
|
|
|
|
### 2. API Route Conflicts ⭐ HIGH
|
|
**Problem**: Playlist downloads conflicted with main playlist routes
|
|
**Root Cause**: Both viewsets at root path `''`
|
|
**Solution**: Moved downloads to dedicated `/downloads/` path
|
|
|
|
**Files Modified**:
|
|
- `backend/playlist/urls.py`
|
|
|
|
**Before**:
|
|
```python
|
|
path('', PlaylistListView),
|
|
path('', include('playlist.urls_download')), # ❌ CONFLICT
|
|
```
|
|
|
|
**After**:
|
|
```python
|
|
path('downloads/', include('playlist.urls_download')), # ✅ NO CONFLICT
|
|
path('', PlaylistListView),
|
|
path('<str:playlist_id>/', PlaylistDetailView),
|
|
```
|
|
|
|
**API Endpoints Now**:
|
|
- `/api/playlist/` - List/create playlists
|
|
- `/api/playlist/<id>/` - Playlist details
|
|
- `/api/playlist/downloads/` - Download management
|
|
- `/api/playlist/downloads/<id>/` - Download details
|
|
- `/api/playlist/downloads/active/` - Active downloads
|
|
- `/api/playlist/downloads/completed/` - Completed downloads
|
|
|
|
**Verification**: ✅ No route conflicts, all endpoints accessible
|
|
|
|

|
|
|
|
### 3. PWA Offline Enhancement ⭐ HIGH
|
|
**Problem**: No dedicated offline caching for playlists
|
|
**Solution**: Complete offline playlist system
|
|
|
|
**New Features**:
|
|
1. **Service Worker Handlers**
|
|

|
|
- `REMOVE_PLAYLIST_CACHE` - Remove cached playlist
|
|
- Intelligent cache-first strategy for audio
|
|
- Network-first for API with fallback
|
|
|
|
2. **IndexedDB Storage**
|
|
- `savePlaylist()` - Store playlist metadata
|
|
- `getOfflinePlaylists()` - Get all offline playlists
|
|
- `updatePlaylistSyncStatus()` - Track sync state
|
|
- `clearAllData()` - Clear all offline data
|
|
|
|
3. **PWA Manager**
|
|
- `cachePlaylist(id, urls)` - Download for offline
|
|
- `removePlaylistCache(id, urls)` - Clear cache
|
|
- Storage quota tracking
|
|
- Online/offline detection
|
|
|
|
4. **React Context API**
|
|
- `usePWA()` hook with all features
|
|
- Real-time online/offline state
|
|
- Cache size monitoring
|
|
- Installation state tracking
|
|
|
|
**Files Modified**:
|
|
- `frontend/src/utils/offlineStorage.ts` - Added playlist methods
|
|
- `frontend/src/utils/pwa.ts` - Added caching functions
|
|
- `frontend/src/context/PWAContext.tsx` - Exposed new APIs
|
|
- `frontend/public/service-worker.js` - Enhanced caching
|
|
|
|
**Verification**: ✅ Playlists work offline, cache persists
|
|
|
|

|
|
|
|
### 4. Security Audit ⭐ CRITICAL

|
|
|
|
**Findings**: ✅ All Secure
|
|
|
|
#### Public Endpoints (No Auth)

|
- ✅ `/api/user/login/` - Login only
|
|
- ✅ `/api/user/register/` - Registration only

|
|
|
#### Authenticated Endpoints (Token Required)
|
|
- ✅ `/api/playlist/*` - Owner isolation via `IsOwnerOrAdmin`
|
|
- ✅ `/api/playlist/downloads/*` - Owner isolation enforced
|
|
- ✅ `/api/audio/*` - User-scoped queries
|
|
- ✅ `/api/channel/*` - Read all, write admin only
|
|
|
|
#### Admin-Only Endpoints
|
|
- ✅ `/api/download/*` - AdminOnly permission
|
|
- ✅ `/api/task/*` - AdminOnly permission
|
|
- ✅ `/api/appsettings/*` - AdminOnly permission
|
|
- ✅ `/admin/*` - Superuser only
|
|
|
|
#### Security Mechanisms
|
|
- ✅ Token authentication (REST Framework)
|
|
- ✅ Session authentication (fallback)
|
|
- ✅ CORS properly configured
|
|
- ✅ CSRF protection enabled
|
|
- ✅ User isolation in queries
|
|
- ✅ Object-level permissions
|
|
- ✅ Admin-only write operations
|
|
- ✅ Proper password validation
|
|
|
|
**Files Verified**:
|
|
- `backend/config/settings.py` - Security settings
|
|
- `backend/common/permissions.py` - Permission classes
|
|
- All `views.py` files - Permission decorators
|
|
|
|
**Verification**: ✅ No security vulnerabilities found
