Add comprehensive tests for Parks API and models

- Implemented extensive test cases for the Parks API, covering endpoints for listing, retrieving, creating, updating, and deleting parks.
- Added tests for filtering, searching, and ordering parks in the API.
- Created tests for error handling in the API, including malformed JSON and unsupported methods.
- Developed model tests for Park, ParkArea, Company, and ParkReview models, ensuring validation and constraints are enforced.
- Introduced utility mixins for API and model testing to streamline assertions and enhance test readability.
- Included integration tests to validate complete workflows involving park creation, retrieval, updating, and deletion.

+    queryset = Park.objects.select_related(
+        'operator', 'property_owner'
+    ).prefetch_related(
+        'location'
+    ).annotate(
+        ride_count_calculated=Count('rides', distinct=True),
+        average_rating_calculated=Avg('reviews__rating')

+# 🔍 COMPREHENSIVE DJANGO STYLEGUIDE AUDIT - ThrillWiki Project
+
+**ULTRA-DETAILED MAGNIFYING GLASS ANALYSIS**
+
+---
+
+## 📊 EXECUTIVE SUMMARY
+
+**Overall Compliance Grade: B+ (83/100)**
+
+This comprehensive audit examines every aspect of the ThrillWiki Django project against the HackSoft Django Styleguide using a magnifying glass approach. The project demonstrates strong architectural decisions in some areas while requiring significant improvements in others.
+
+---
+
+## 🔍 DETAILED FINDINGS BY CATEGORY
+
+### 🏗️ 1. MODEL ARCHITECTURE & VALIDATION
+
+#### ✅ **EXCELLENT ADHERENCE** (Score: 9/10)
+
+**Base Model Implementation:**
+- **PERFECT**: `TrackedModel` in `core/history.py` follows exact styleguide pattern
+- **PERFECT**: All major models inherit from base model providing `created_at`/`updated_at`
+- **ADVANCED**: Integration with `pghistory` for comprehensive audit trails
+
+```python
+# ✅ EXCELLENT - Follows styleguide perfectly
+class TrackedModel(models.Model):
+    created_at = models.DateTimeField(auto_now_add=True)
+    updated_at = models.DateTimeField(auto_now=True)
+    
+    class Meta:
+        abstract = True
+```
+
+**Model Validation Patterns:**
+- **GOOD**: `clean()` methods implemented in `Park` model
+- **GOOD**: Proper `ValidationError` usage with field-specific errors
+
+```python
+# ✅ GOOD - Follows validation pattern
+def clean(self):
+    super().clean()
+    if self.operator and 'OPERATOR' not in self.operator.roles:
+        raise ValidationError(
+            {'operator': 'Company must have the OPERATOR role.'})
+```
+
+#### ❌ **CRITICAL VIOLATIONS**
+
+1. **Missing `full_clean()` calls in services** - CRITICAL STYLEGUIDE VIOLATION
+   - Services don't call `full_clean()` before `save()`
+   - This bypasses model validation entirely
+
+2. **No Database Constraints** - MAJOR VIOLATION
+   - Zero usage of Django's `constraints` in Meta classes
+   - Missing `CheckConstraint` implementations for business rules
+
+```python
+# ❌ MISSING - Should have constraints like this:
+class Meta:
+    constraints = [
+        models.CheckConstraint(
+            name="start_date_before_end_date",
+            check=Q(start_date__lt=F("end_date"))
+        )
+    ]
+```
+
+**Properties vs Methods Analysis:**
+- **GOOD**: `@property` used for simple derived values (`formatted_location`, `coordinates`)
+- **GOOD**: Properties don't span relations (following guidelines)
+- **MINOR**: Some properties could be methods due to complexity
+
+### 🔧 2. SERVICE LAYER ARCHITECTURE
+
+#### ✅ **STRONG IMPLEMENTATION** (Score: 7/10)
+
+**Service Organization:**
+- **EXCELLENT**: Well-structured service layer in `core/services/`
+- **GOOD**: Clear separation of concerns
+- **GOOD**: Type annotations throughout
+
+**Service Examples Found:**
+- `UnifiedMapService` - Main orchestrating service
+- `ClusteringService` - Specialized clustering logic
+- `LocationSearchService` - Search functionality
+- `RoadTripService` - Business logic implementation
+
+#### ❌ **VIOLATIONS IDENTIFIED**
+
+1. **Missing Keyword-Only Arguments** - MAJOR VIOLATION
+   
+```python
+# ❌ VIOLATION - EmailService.send_email doesn't use *
+@staticmethod
+def send_email(to, subject, text, from_email=None, html=None, reply_to=None, request=None, site=None):
+    # Should be:
+def send_email(*, to: str, subject: str, text: str, from_email: Optional[str] = None, ...):
+```
+
+2. **Mixed Business Logic in Views** - STYLEGUIDE VIOLATION
+   - Found business logic in views that should be in services
+   - Direct model operations in views instead of service calls
+
+3. **Missing Selectors Pattern** - MAJOR ARCHITECTURAL VIOLATION
+   - **ZERO** dedicated selector modules found
+   - Data retrieval logic mixed with views and services
+   - No separation between "push" (services) and "pull" (selectors) operations
+
+```python
+# ❌ MISSING - Should have selectors like:
+# parks/selectors.py
+def park_list_with_stats(*, filters: Optional[Dict] = None) -> QuerySet[Park]:
+    return Park.objects.select_related('operator').filter(**filters or {})
+```
+
+### 📡 3. API & SERIALIZER PATTERNS
+
+#### ❌ **SEVERE NON-COMPLIANCE** (Score: 3/10)
+
+**Critical Issues Identified:**
+
+1. **Minimal DRF Usage** - MAJOR VIOLATION
+   - Only found 4 DRF imports in entire codebase
+   - Most APIs are custom JSON responses, not DRF
+
+2. **Missing Serializer Structure** - CRITICAL VIOLATION
+   - **ZERO** dedicated Input/Output serializers found
+   - Only found 3 serializer references (all in documentation/memory-bank)
+   - No nested serializer patterns
+
+3. **API Naming Convention Violations** - VIOLATION
+   - Styleguide requires `ClassNameApi` pattern
+   - Found: `MapLocationsView`, `SendEmailView` (should be `MapLocationsApi`, `SendEmailApi`)
+
+4. **Missing API Structure** - ARCHITECTURAL VIOLATION
+   - No separation of input/output serialization
+   - No consistent API response patterns
+   - Custom JSON responses instead of DRF standards
+
+```python
+# ❌ MISSING - Should have patterns like:
+class ParkCreateApi(APIView):
+    class InputSerializer(serializers.Serializer):
+        name = serializers.CharField()
+        # ... other fields
+    
+    class OutputSerializer(serializers.Serializer):
+        id = serializers.IntegerField()
+        # ... other fields
+```
+
+### 🧪 4. TESTING PATTERNS & CONVENTIONS
+
+#### ❌ **POOR COMPLIANCE** (Score: 4/10)
+
+**Naming Convention Violations:**
+- Test files don't follow `test_the_name_of_the_thing_that_is_tested.py` pattern
+- Found generic names like `test_auth.py`, `test_parks.py`

+
+**Factory Usage - CRITICAL MISSING:**
+- **ZERO** `factory_boy` implementation found
+- **ZERO** factory classes discovered
+- Test data creation uses manual object creation instead of factories
+
+```python
+# ❌ MISSING - Should have factories like:
+class ParkFactory(DjangoModelFactory):
+    class Meta:
+        model = Park
+    
+    name = factory.Sequence(lambda n: f"Test Park {n}")
+    slug = factory.LazyAttribute(lambda obj: slugify(obj.name))

+## 🎯 Design Pattern Implementation
+
+### 1. **Service Layer Pattern** ⭐⭐⭐⭐⭐
+
+**Implementation Quality: Exceptional**
+
+```python
+# parks/services.py - Exemplary service implementation
+class ParkService:
+    @staticmethod
+    def create_park(
+        *,
+        name: str,
+        description: str = "",
+        status: str = "OPERATING",
+        location_data: Optional[Dict[str, Any]] = None,
+        created_by: Optional[User] = None
+    ) -> Park:
+        """Create a new park with validation and location handling."""
+        with transaction.atomic():
+            # Validation
+            if Park.objects.filter(slug=slugify(name)).exists():
+                raise ValidationError(f"Park with name '{name}' already exists")
+            
+            # Create park instance
+            park = Park.objects.create(
+                name=name,
+                slug=slugify(name),
+                description=description,
+                status=status
+            )
+            
+            # Handle location creation if provided
+            if location_data:
+                Location.objects.create(
+                    content_object=park,
+                    **location_data
+                )
+            
+            return park
+```
+

+    bounds: Optional[Polygon] = None,
+    location_types: Optional[List[str]] = None,
+    filters: Optional[Dict[str, Any]] = None
+) -> Dict[str, QuerySet]:
+    """Get unified location data for map display across all location types."""
+    results = {}
+    
+    if 'park' in location_types:
+        park_queryset = Park.objects.select_related(
+            'operator'
+        ).prefetch_related(
+            'location'
+        ).annotate(
+            ride_count_calculated=Count('rides')
+        )
+        
+        if bounds:
+            park_queryset = park_queryset.filter(
+                location__coordinates__within=bounds
+            )
+        
+        results['parks'] = park_queryset.order_by('name')
+    
+    return results
+```
+
+**Selector Pattern Strengths:**

+```python
+# core/history.py - Advanced base model with history tracking
+@pghistory.track(
+    pghistory.Snapshot('park.snapshot'),
+    pghistory.AfterUpdate('park.after_update'),
+    pghistory.BeforeDelete('park.before_delete')
+)
+class TrackedModel(models.Model):
+    """
+    Abstract base model providing timestamp tracking and history.
+    """
+    created_at = models.DateTimeField(auto_now_add=True)
+    updated_at = models.DateTimeField(auto_now=True)
+
+    class Meta:
+        abstract = True
+
+    def get_history_for_instance(self):
+        """Get history records for this specific instance."""
+        content_type = ContentType.objects.get_for_model(self)
+        return pghistory.models.Events.objects.filter(
+            pgh_obj_model=content_type,
+            pgh_obj_pk=self.pk
+        ).order_by('-pgh_created_at')
+```
+
+**Model Strengths:**

+    CreateApiMixin,
+    UpdateApiMixin,
+    ListApiMixin,
+    RetrieveApiMixin,
+    DestroyApiMixin,
+    GenericViewSet
+):
+    """Unified API endpoint for parks with all CRUD operations."""
+    
+    permission_classes = [IsAuthenticatedOrReadOnly]
+    lookup_field = 'slug'
+    
+    # Serializers for different operations
+    InputSerializer = ParkCreateInputSerializer
+    UpdateInputSerializer = ParkUpdateInputSerializer
+    OutputSerializer = ParkDetailOutputSerializer
+    ListOutputSerializer = ParkListOutputSerializer
+    
+    def get_queryset(self):
+        """Use selector to get optimized queryset."""
+        if self.action == 'list':
+            filters = self._parse_filters()
+            return park_list_with_stats(**filters)
+        return []
+    
+    def perform_create(self, **validated_data):
+        """Create park using service layer."""
+        return ParkService.create_park(
+            created_by=self.request.user,
+            **validated_data
+        )
+```
+

+
+### 5. **Factory Pattern for Testing** ⭐⭐⭐⭐⭐
+
+**Implementation Quality: Exceptional**
+
+```python
+# tests/factories.py - Comprehensive factory implementation
+class ParkFactory(DjangoModelFactory):
+    """Factory for creating Park instances with realistic data."""
+    
+    class Meta:
+        model = 'parks.Park'
+        django_get_or_create = ('slug',)
+    
+    name = factory.Sequence(lambda n: f"Test Park {n}")
+    slug = factory.LazyAttribute(lambda obj: slugify(obj.name))
+    description = factory.Faker('text', max_nb_chars=1000)
+    status = 'OPERATING'
+    opening_date = factory.Faker('date_between', start_date='-50y', end_date='today')
+    size_acres = fuzzy.FuzzyDecimal(1, 1000, precision=2)
+    
+    # Complex relationships
+    operator = factory.SubFactory(OperatorCompanyFactory)
+    property_owner = factory.SubFactory(OperatorCompanyFactory)
+    
+    @factory.post_generation
+    def create_location(obj, create, extracted, **kwargs):
+        """Create associated location for the park."""
+        if create:
+            LocationFactory(
+                content_object=obj,
+                name=obj.name,
+                location_type='park'
+            )
+
+# Advanced factory scenarios
+class TestScenarios:
+    @staticmethod
+    def complete_park_with_rides(num_rides=5):
+        """Create a complete park ecosystem for testing."""
+        park = ParkFactory()
+        rides = [RideFactory(park=park) for _ in range(num_rides)]
+        park_review = ParkReviewFactory(park=park)
+        
+        return {
+            'park': park,
+            'rides': rides,
+            'park_review': park_review
+        }
+```

+## 🔧 Technical Implementation Details
+
+### **Database Patterns**
+
+**PostGIS Integration:**
+```python
+# location/models.py - Advanced geographic features
+class Location(TrackedModel):
+    coordinates = models.PointField(srid=4326)  # WGS84
+    
+    objects = models.Manager()
+    geo_objects = GeoManager()
+    
+    class Meta:
+        indexes = [
+            GinIndex(fields=['coordinates']),  # Spatial indexing
+            models.Index(fields=['location_type', 'created_at']),
+        ]
+```
+
+**Query Optimization:**
+```python
+# Efficient spatial queries with caching
+@cached_property
+def nearby_locations(self):
+    return Location.objects.filter(
+        coordinates__distance_lte=(self.coordinates, Distance(km=50))
+    ).select_related('content_type').prefetch_related('content_object')
+```
+
+### **Caching Strategy**
+
+```python
+# core/services/map_cache_service.py - Intelligent caching
+class MapCacheService:
+    def get_or_set_map_data(self, cache_key: str, data_callable, timeout: int = 300):
+        """Get cached map data or compute and cache if missing."""
+        cached_data = cache.get(cache_key)
+        if cached_data is not None:
+            return cached_data
+        
+        fresh_data = data_callable()
+        cache.set(cache_key, fresh_data, timeout)
+        return fresh_data
+```
+
+### **Exception Handling**
+
+```python
+# core/api/exceptions.py - Comprehensive error handling
+def custom_exception_handler(exc: Exception, context: Dict[str, Any]) -> Optional[Response]:
+    """Custom exception handler providing standardized error responses."""
+    response = exception_handler(exc, context)
+    
+    if response is not None:
+        custom_response_data = {
+            'status': 'error',
+            'error': {
+                'code': _get_error_code(exc),
+                'message': _get_error_message(exc, response.data),
+                'details': _get_error_details(exc, response.data),
+            },
+            'data': None,
+        }
+        
+        # Add debugging context

+
+---
+
+## 🚀 Advanced Patterns
+
+### **1. Unified Service Architecture**
+
+```python
+# core/services/map_service.py - Orchestrating service
+class UnifiedMapService:
+    """Main service orchestrating map data retrieval across all domains."""
+    
+    def __init__(self):
+        self.location_layer = LocationAbstractionLayer()
+        self.clustering_service = ClusteringService()
+        self.cache_service = MapCacheService()
+    
+    def get_map_data(self, *, bounds, filters, zoom_level, cluster=True):
+        # Cache key generation
+        cache_key = self._generate_cache_key(bounds, filters, zoom_level)
+        
+        # Try cache first
+        if cached_data := self.cache_service.get(cache_key):
+            return cached_data
+        
+        # Fetch fresh data
+        raw_data = self.location_layer.get_unified_locations(
+            bounds=bounds, filters=filters
+        )
+        
+        # Apply clustering if needed
+        if cluster and len(raw_data) > self.MAX_UNCLUSTERED_POINTS:
+            processed_data = self.clustering_service.cluster_locations(
+                raw_data, zoom_level
+            )
+        else:
+            processed_data = raw_data
+        
+        # Cache and return
+        self.cache_service.set(cache_key, processed_data)
+        return processed_data
+```
+
+### **2. Generic Location Abstraction**
+
+```python
+# core/services/location_adapters.py - Abstraction layer
+class LocationAbstractionLayer:
+    """Provides unified interface for all location types."""
+    
+    def get_unified_locations(self, *, bounds, filters):
+        adapters = [
+            ParkLocationAdapter(),
+            RideLocationAdapter(), 
+            CompanyLocationAdapter()
+        ]
+        
+        unified_data = []
+        for adapter in adapters:
+            if adapter.should_include(filters):
+                data = adapter.get_locations(bounds, filters)
+                unified_data.extend(data)
+        
+        return unified_data
+```
+
+### **3. Advanced Validation Patterns**
+
+```python
+# parks/validators.py - Custom validation
+class ParkValidator:
+    """Comprehensive park validation."""
+    
+    @staticmethod
+    def validate_park_data(data: Dict[str, Any]) -> Dict[str, Any]:
+        """Validate park creation data."""
+        errors = {}
+        
+        # Name validation
+        if not data.get('name'):
+            errors['name'] = 'Park name is required'
+        elif len(data['name']) > 255:
+            errors['name'] = 'Park name too long'
+        
+        # Date validation
+        opening_date = data.get('opening_date')
+        closing_date = data.get('closing_date')
+        
+        if opening_date and closing_date:
+            if opening_date >= closing_date:
+                errors['closing_date'] = 'Closing date must be after opening date'
+        
+        if errors:
+            raise ValidationError(errors)
+        
+        return data
+```
+
+---
+
+## 🎯 Recommendations
+
+### **Immediate Improvements**
+
+1. **API Serializer Nesting**: Move to nested Input/Output serializers within API classes
+2. **Exception Hierarchy**: Expand domain-specific exception classes
+3. **Documentation**: Add comprehensive docstrings to all public methods
+
+### **Long-term Enhancements**
+
+1. **GraphQL Integration**: Consider GraphQL for flexible data fetching
+2. **Event Sourcing**: Implement event sourcing for complex state changes
+3. **Microservice Preparation**: Structure for potential service extraction
