location queries CREATE INDEX idx_park_location_coordinates ON parks_parklocation USING GIST (coordinates); CREATE INDEX idx_ride_location_coordinates ON rides_ridelocation USING GIST (coordinates); -- Text search indexes CREATE INDEX idx_park_name_search ON parks_park USING GIN (to_tsvector('english', name)); CREATE INDEX idx_ride_name_search ON rides_ride USING GIN (to_tsvector('english', name)); -- Foreign key indexes for joins CREATE INDEX idx_ride_park_id ON rides_ride (park_id); CREATE INDEX idx_ride_manufacturer_id ON rides_ride (manufacturer_id); CREATE INDEX idx_review_user_id ON reviews_review (user_id); -- Composite indexes for common queries CREATE INDEX idx_ride_category_status ON rides_ride (category, status); CREATE INDEX idx_park_country_state ON parks_parklocation (country, state); ``` #### Query Optimization - **Select Related**: Minimize database queries with `select_related()` for foreign keys - **Prefetch Related**: Optimize many-to-many and reverse foreign key queries - **Database Functions**: Use PostgreSQL-specific functions for complex queries - **Connection Pooling**: Efficient database connection management --- ## API Architecture ### RESTful

└─────────────────┘ │ • Users │ │ • Relevance │ └─────────────────┘ └─────────────────┘ ``` #### Search Features 1. **Fuzzy Search**: Typo-tolerant text matching 2. **Autocomplete**: Real-time search suggestions 3. **Faceted Search**: Multi-dimensional filtering 4. **Geographic Search**: Location-based results 5. **Semantic Search**: Context-aware matching ### Search Implementation #### PostgreSQL Full-Text Search ```sql -- Text search vectors ALTER TABLE parks_park ADD COLUMN search_vector tsvector; ALTER TABLE rides_ride ADD COLUMN search_vector tsvector; -- Update search vectors UPDATE parks_park SET search_vector = to_tsvector('english', coalesce(name, '') || ' ' || coalesce(description, '')); -- Search indexes CREATE INDEX idx_park_search_vector ON parks_park USING GIN (search_vector); CREATE INDEX idx_ride_search_vector ON rides_ride USING GIN (search_vector); ``` #### Search API Endpoints ```python # Core Search GET /api/v1/core/entities/search/ # Multi-entity fuzzy search GET /api/v1/core/entities/suggestions/ # Quick autocomplete suggestions # Entity-Specific Search GET /api/v1/parks/search-suggestions/ # Park search suggestions GET /api/v1/rides/search-suggestions/ # Ride search suggestions GET /api/v1/rides/search/companies/ # Company search for rides GET /api/v1/parks/search/companies/ # Company search for parks ``` #### Search Ranking Algorithm ```python def calculate_search_score(entity, query, user_location=None): score = 0 # Text relevance (40%) text_score = calculate_text_relevance(entity.name, entity.description, query) score += text_score * 0.4 # Popularity (30%) popularity_score = calculate_popularity(entity.reviews_count, entity.average_rating) score += popularity_score * 0.3 # Recency (15%) recency_score = calculate_recency(entity.updated_at) score += recency_score * 0.15 # Geographic proximity (15%) if user_location and entity.location: proximity_score = calculate_proximity(user_location, entity.location) score += proximity_score * 0.15 return score ``` ### Discovery Features #### Trending Content - **Algorithm**: Combines views, ratings, and recency - **Time Periods**: Daily, weekly, monthly trending - **Categories**: Separate trending for parks and rides - **Real-time Updates**: Celery tasks update trending calculations #### Recommendations - **Collaborative Filtering**: Based on user behavior patterns - **Content-Based**: Similar parks/rides recommendations - **Geographic**: Nearby attractions suggestions - **Personalized**: User preference-based recommendations #### New Content Discovery - **Recently Added**: Latest parks and rides in database - **Recently Opened**: Newly opened attractions - **Coming Soon**: Under construction attractions - **Updated Content**: Recently modified entries --- ## Maps & Location Services ### Geographic Data Architecture #### PostGIS Integration ```sql -- Enable PostGIS extension CREATE EXTENSION postgis; -- Location tables with geographic data CREATE TABLE parks_parklocation ( id SERIAL PRIMARY KEY, park_id INTEGER REFERENCES parks_park(id), coordinates GEOMETRY(POINT, 4326), country VARCHAR(100), state VARCHAR(100), city VARCHAR(100), address TEXT, timezone VARCHAR(50) ); -- Spatial indexes CREATE INDEX idx_park_coordinates ON parks_parklocation USING GIST (coordinates); CREATE INDEX idx_ride_coordinates ON rides_ridelocation USING GIST (coordinates); ``` #### Location Data Model ```python class ParkLocation(models.Model): park = models.OneToOneField(Park, on_delete=models.CASCADE) coordinates = models.PointField(srid=4326, null=True, blank=True) country = models.CharField(max_length=100) state = models.CharField(max_length=100) city = models.CharField(max_length=100) address = models.TextField(blank=True) timezone = models.CharField(max_length=50, default='UTC') class Meta: indexes = [ models.Index(fields=['country', 'state']), GistIndex(fields=['coordinates']), ] ``` ### Maps API Features #### Location Endpoints ```python # Map Data GET /api/v1/maps/locations/ # Get map locations with clustering GET /api/v1/maps/locations/{type}/{id}/ # Detailed location information GET /api/v1/maps/search/ # Search locations by text GET /api/v1/maps/bounds/ # Get locations within bounds GET /api/v1/maps/stats/ # Map service statistics # Cache Management GET /api/v1/maps/cache/ # Cache status (admin only) POST /api/v1/maps/cache/invalidate/ # Invalidate cache (admin only) ``` #### Geographic Queries ```python # Find parks within radius def parks_within_radius(center_point, radius_km): return Park.objects.filter( location__coordinates__distance_lte=( center_point, Distance(km=radius_km) ) ).annotate( distance=Distance('location__coordinates', center_point) ).order_by('distance') # Find parks in bounding box def parks_in_bounds(sw_lat, sw_lng, ne_lat, ne_lng): bbox = Polygon.from_bbox((sw_lng, sw_lat, ne_lng, ne_lat)) return Park.objects.filter( location__coordinates__within=bbox ) ``` #### Clustering Algorithm ```python def cluster_locations(locations, zoom_level): """ Cluster nearby locations based on zoom level Higher zoom = more granular clustering """ cluster_distance = get_cluster_distance(zoom_level) clusters = [] for location in locations: # Find existing cluster within distance existing_cluster = find_nearby_cluster( clusters, location, cluster_distance ) if existing_cluster: existing_cluster['locations'].append(location) existing_cluster['count'] += 1 else: # Create new cluster clusters.append({ 'center': location['coordinates'], 'locations': [location], 'count': 1 }) return clusters ``` ### Location Services #### Geocoding Integration - **Address to Coordinates**: Convert addresses to lat/lng - **Reverse Geocoding**: Convert coordinates to addresses - **Timezone Detection**: Automatic timezone assignment - **Country/State Normalization**: Consistent location naming #### Map Features - **Interactive Maps**: Zoom, pan, marker clustering - **Layer Controls**: Toggle parks, rides, different categories - **Info Windows**: Detailed information on marker click - **Route Planning**: Directions to parks and attractions - **Offline Support**: Cached map data for offline viewing --- ## Performance & Scalability ### Caching Strategy

Content Analytics ```python # Content performance tracking class ContentAnalytics: @staticmethod def update_view_count(content_type, content_id): # Increment view count with Redis cache_key =

= self.get_response(request) # Analyze queries queries = connection.queries if len(queries) > 10: # Alert on N+1 queries logger.warning(f"High query count: {len(queries)} for {request.path}") slow_queries = [q for q in queries if float(q['time']) > 0.1] if slow_queries: logger.warning(f"Slow queries detected: {len(slow_queries)}") return response ``` #### Error Tracking ```python # Custom
