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.

|
||||
|
||||
## 🏆 Exceptional Strengths
|
||||
|
||||
### 1. ✅ **OUTSTANDING: Base Model & History Architecture** (Score: 10/10)
|
||||
|
||||
The project demonstrates **exemplary** implementation of Django styleguide base model patterns:
|
||||
|
||||
```python
|
||||
# core/history.py - Perfect base model implementation
|
||||
class TrackedModel(models.Model):
|
||||
created_at = models.DateTimeField(auto_now_add=True)
|
||||
updated_at = models.DateTimeField(auto_now=True)
|
||||
|
||||
class Meta:
|
||||
abstract = True
|
||||
```
|
||||
|
||||
**Advanced Features:**
|

# parks/selectors.py - Proper selector implementation
|
||||
def park_list_with_stats(*, filters: Optional[Dict[str, Any]] = None) -> QuerySet[Park]:
|
||||
"""Get parks optimized for list display with basic stats."""
|
||||
queryset = Park.objects.select_related(
|
||||
'operator',
|
||||
'property_owner'
|
||||
).prefetch_related(

class ParkFactory(DjangoModelFactory):
|
||||
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))
|
||||
# ... comprehensive field definitions
|
||||
|
||||
@factory.post_generation
|
||||
def create_location(obj, create, extracted, **kwargs):
|
||||
"""Create a location for the park."""
|
||||
if create:

||||
# config/django/base.py - Proper settings structure
|
||||
DJANGO_APPS = [
|
||||
"django.contrib.admin",
|
||||
# ... standard Django apps
|
||||
]
|
||||
|

||||
"accounts",
|
||||
"parks",
|
||||
# ... project apps
|
||||
]
|
||||
|

## 🎯 Areas for Enhancement
|
||||
|
||||
### 1. ⚠️ **API Serialization Patterns** (Score: 7/10)
|
||||
|
||||
**Current Implementation vs. Styleguide Requirements:**
|
||||
|
||||
The project has **good API patterns** but could better align with styleguide specifications:
|
||||
|
||||
**Strengths:**
|
||||
- ✅ Proper API mixins with standardized response patterns
|
||||
- ✅ Input/Output serializer separation in newer APIs
|
||||
- ✅ Correct use of keyword-only arguments
|
||||
|
||||
**Enhancement Opportunities:**
|
||||
```python
|
||||
# Current: Good but can be improved
|
||||
class ParkApi(CreateApiMixin, ListApiMixin, GenericViewSet):
|
||||
InputSerializer = ParkCreateInputSerializer
|
||||
OutputSerializer = ParkDetailOutputSerializer
|
||||
|
||||
# Styleguide preference: Nested serializers
|
||||
class ParkCreateApi(APIView):
|
||||
class InputSerializer(serializers.Serializer):
|
||||
name = serializers.CharField()
|
||||
# ... fields
|
||||
|
||||
class OutputSerializer(serializers.Serializer):
|
||||
id = serializers.IntegerField()
|
||||
# ... fields
|
||||
```
|
||||
|
||||
**Recommendations:**
|
||||
- Migrate to nested Input/Output serializers within API classes
|
||||
- Standardize API naming to `ClassNameApi` pattern consistently
|
||||
- Enhance serializer reuse patterns
|
||||
|
||||
### 2. ⚠️ **Exception Handling Enhancement** (Score: 8/10)
|
||||
|
||||
**Current State:** Good foundation with room for styleguide alignment
|
||||
|
||||
**Existing Strengths:**
|
||||
- ✅ Custom exception handler implemented
|
||||
- ✅ Proper error response standardization
|
||||
- ✅ Comprehensive logging integration
|
||||
|
||||
**Enhancement Opportunities:**
|
||||
```python
|
||||
# Current: Good custom exceptions
|
||||
class ThrillWikiException(Exception):
|
||||
def to_dict(self) -> Dict[str, Any]:
|
||||
return {'error_code': self.error_code, 'message': self.message}
|
||||
|
||||
# Styleguide alignment: More specific exceptions
|
||||
class ParkNotFoundError(ApplicationError):
|
||||
message = "Park not found"
|
||||
status_code = 404
|
||||
|
||||
class InvalidParkDataError(ValidationError):
|
||||
message = "Invalid park data provided"
|
||||
```
