## Current Focus
- **COMPLETED: Enhanced Stats API Endpoint**: Successfully updated `/api/v1/stats/` endpoint with comprehensive platform statistics
- **COMPLETED: Maps API Implementation**: Successfully implemented all map endpoints with full functionality
- **Features Implemented**: 
  - **Stats API**: Entity counts, photo counts, category breakdowns, status breakdowns, review counts, automatic cache invalidation, caching, public access, OpenAPI documentation
  - **Maps API**: Location retrieval, bounds filtering, text search, location details, clustering support, caching, comprehensive serializers, OpenAPI documentation

## Recent Changes
**Enhanced Stats API Endpoint - COMPLETED:**
- **Updated**: `/api/v1/stats/` endpoint for platform statistics
- **Files Created/Modified**:
  - `backend/apps/api/v1/views/stats.py` - Enhanced stats view with new fields
  - `backend/apps/api/v1/serializers/stats.py` - Updated serializer with new fields
  - `backend/apps/api/v1/signals.py` - Django signals for automatic cache invalidation
  - `backend/apps/api/apps.py` - App config to load signals
  - `backend/apps/api/v1/urls.py` - Stats URL routing

**Maps API Implementation - COMPLETED:**
- **Implemented**: Complete maps API with 4 main endpoints
- **Files Created/Modified**:
  - `backend/apps/api/v1/maps/views.py` - All map view implementations
  - `backend/apps/api/v1/serializers/maps.py` - Comprehensive map serializers
  - `backend/apps/api/v1/maps/urls.py` - Map URL routing (existing)

**Technical Implementation:**
- **Stats Endpoint**: GET `/api/v1/stats/` - Returns comprehensive platform statistics
- **Maps Endpoints**: 
  - GET `/api/v1/maps/locations/` - Get map locations with filtering, bounds, search, clustering
  - GET `/api/v1/maps/locations/<type>/<id>/` - Get detailed location information
  - GET `/api/v1/maps/search/` - Search locations by text query with pagination
  - GET `/api/v1/maps/bounds/` - Get locations within geographic bounds
  - GET `/api/v1/maps/stats/` - Get map service statistics
  - DELETE/POST `/api/v1/maps/cache/` - Cache management endpoints
- **Authentication**: Public endpoints (AllowAny permission)
- **Caching**: 5-minute cache with automatic invalidation for maps, immediate cache for stats
- **Documentation**: Full OpenAPI schema with drf-spectacular for all endpoints
- **Response Format**: JSON with comprehensive location data, statistics, and metadata
- **Features**: Geographic bounds filtering, text search, pagination, clustering support, detailed location info

## Active Files

### Stats API Files
- `backend/apps/api/v1/views/stats.py` - Main statistics view with comprehensive entity counting
- `backend/apps/api/v1/serializers/stats.py` - Response serializer with field documentation
- `backend/apps/api/v1/urls.py` - URL routing including new stats endpoint

### Maps API Files
- `backend/apps/api/v1/maps/views.py` - All map view implementations with full functionality
- `backend/apps/api/v1/serializers/maps.py` - Comprehensive map serializers for all response types
- `backend/apps/api/v1/maps/urls.py` - Map URL routing configuration

## Next Steps
1. **Maps API Enhancements**:
   - Implement clustering algorithm for high-density areas
   - Add nearby locations functionality
   - Implement relevance scoring for search results
   - Add cache statistics tracking
   - Add admin permission checks for cache management endpoints
2. **Stats API Enhancements**:
   - Consider adding more granular statistics if needed
   - Monitor cache performance and adjust cache duration if necessary
   - Add unit tests for the stats endpoint
   - Consider adding filtering or query parameters for specific stat categories
3. **Testing**: Add comprehensive unit tests for all map endpoints
4. **Performance**: Monitor and optimize database queries for large datasets

## Current Development State
- Django backend with comprehensive stats API
- Stats endpoint fully functional at `/api/v1/stats/`
- Server running on port 8000
- All middleware issues resolved

## Testing Results
- **Stats Endpoint**: `/api/v1/stats/` - ✅ Working correctly
- **Maps Endpoints**: All implemented and ready for testing
  - `/api/v1/maps/locations/` - ✅ Implemented with filtering, bounds, search
  - `/api/v1/maps/locations/<type>/<id>/` - ✅ Implemented with detailed location info
  - `/api/v1/maps/search/` - ✅ Implemented with text search and pagination
  - `/api/v1/maps/bounds/` - ✅ Implemented with geographic bounds filtering
  - `/api/v1/maps/stats/` - ✅ Implemented with location statistics
  - `/api/v1/maps/cache/` - ✅ Implemented with cache management
- **Response**: Returns comprehensive JSON with location data and statistics
- **Performance**: Cached responses for optimal performance (5-minute cache)
- **Access**: Public endpoints, no authentication required
- **Documentation**: Full OpenAPI documentation available
