# Django Best Practices Analysis - ThrillWiki Project
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This analysis evaluates the ThrillWiki Django project against established Django best practices as defined in the HackSoft Django Styleguide. The project demonstrates strong adherence to many best practices while having opportunities for improvement in some areas.
|
||||
|
||||
**Overall Assessment: ⭐⭐⭐⭐☆ (8/10)**
|
||||
|
||||
## Key Strengths
|
||||
|
||||
### ✅ Model Architecture & Base Models
|
||||
- **Excellent**: Implements proper base model pattern with `TrackedModel` in `core/history.py`
|
||||
- **Strong**: All major models inherit from `TrackedModel` providing consistent `created_at`/`updated_at` fields
|
||||
- **Advanced**: Complex historical tracking with `pghistory` integration for full audit trails
|
||||
- **Good**: Proper use of abstract base classes (`SluggedModel`) for shared functionality
|
||||
|
||||
```python
|
||||
# core/history.py - Proper 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
|
||||
```
|
||||
|
||||
### ✅ Service Layer Architecture
|
||||
- **Excellent**: Well-structured service layer in `core/services/`
|
||||
- **Strong**: Clear separation of concerns with dedicated services:
|
||||
- `UnifiedMapService` - Main orchestrating service
|
||||
- `ClusteringService` - Specialized clustering logic
|
||||
- `LocationSearchService` - Search functionality
|
||||
- `RoadTripService` - Business logic for trip planning
|
||||
- **Good**: Services follow keyword-only argument patterns
|
||||
- **Good**: Type annotations throughout service layer
|
||||
|
||||
```python
|
||||
# Example of proper service implementation
|
||||
class UnifiedMapService:
|
||||
def get_map_data(
|
||||
self,
|
||||
bounds: Optional[GeoBounds] = None,
|
||||
filters: Optional[MapFilters] = None,
|
||||
zoom_level: int = DEFAULT_ZOOM_LEVEL,
|
||||
cluster: bool = True,
|
||||
use_cache: bool = True
|
||||
) -> MapResponse:
|
||||
```
|
||||
|
||||
### ✅ Template Organization & Structure
|
||||
- **Excellent**: Proper template inheritance with `base/base.html`
|
||||
- **Strong**: Logical template directory structure by app
|
||||
- **Good**: Extensive use of partial templates for HTMX integration
|
||||
- **Good**: Reusable components in `partials/` directories
|
||||
- **Advanced**: HTMX integration for dynamic updates
|
||||
|
||||
```html
|
||||
<!-- Proper template structure -->
|
||||
{% extends "base/base.html" %}
|
||||
{% load static %}
|
||||
|
||||
{% block title %}{{ area.name }} - {{ area.park.name }} - ThrillWiki{% endblock %}
|
||||
```
|
||||
|
||||
### ✅ URL Structure & Organization
|
||||
- **Excellent**: Clear URL namespacing by app
|
||||
- **Strong**: RESTful URL patterns with proper slug usage
|
||||
- **Good**: Separation of HTML views and API endpoints
|
||||
- **Good**: Logical grouping of related endpoints
|
||||
|
||||
```python
|
||||
# parks/urls.py - Well-organized URL structure
|
||||
app_name = "parks"
|
||||
urlpatterns = [
|
||||
path("", views_search.ParkSearchView.as_view(), name="park_list"),
|
||||
path("create/", views.ParkCreateView.as_view(), name="park_create"),
|
||||
path("<slug:slug>/", views.ParkDetailView.as_view(), name="park_detail"),
|
||||
]
|
||||
```
|
||||
|
||||
### ✅ Testing Infrastructure
|
||||
- **Strong**: Comprehensive testing setup with coverage reporting
|
||||
- **Good**: Separate unit tests and E2E tests with Playwright
|
||||
- **Good**: Custom test runner with coverage integration
|
||||
- **Good**: Clear test organization by app
|
||||
|
||||
## Areas for Improvement
|
||||
|
||||
### ⚠️ Settings Organization
|
||||
**Current State**: Single monolithic `settings.py` file
|
||||
**Django Styleguide Recommendation**: Structured settings with separate modules
|
||||
|
||||
**Issues Identified**:
|
||||
- All settings in one file (`thrillwiki/settings.py`)
|
||||
- No environment-based configuration separation
|
||||
- Hard-coded values mixed with environment-dependent settings
|
||||
|
||||
**Recommended Structure**:
|
||||
```
|
||||
config/
|
||||
├── django/
|
||||
│ ├── base.py # Common settings
|
||||
│ ├── local.py # Development settings
|
||||
│ ├── production.py # Production settings
|
||||
│ └── test.py # Test settings
|
||||
└── settings/
|
||||
├── celery.py # Celery configuration
|
||||
├── cors.py # CORS settings
|
||||
└── sentry.py # Sentry configuration
|
||||
```
|
||||
|
||||
### ⚠️ Selectors Pattern Implementation
|
||||
**Current State**: Limited selector pattern usage
|
||||
**Django Styleguide Recommendation**: Clear separation between services (push) and selectors (pull)
|
||||
|
||||
**Issues Identified**:
|
||||
- Data retrieval logic mixed in views and services
|
||||
- No dedicated `selectors.py` modules
|
||||
- Query optimization scattered across multiple locations
|
||||
|
||||
**Recommended Pattern**:
|
||||
```python
|
||||
# parks/selectors.py
|
||||
def park_list_with_stats(*, filters: Optional[Dict] = None) -> QuerySet[Park]:
|
||||
"""Get parks with optimized queries for list display"""
|
||||
queryset = Park.objects.select_related('operator', 'property_owner')
|
||||
if filters:
|
||||
queryset = queryset.filter(**filters)
|
||||
return queryset.order_by('name')
|
||||
```
|
||||
|
||||
### ⚠️ API & Serializers Structure
|
||||
**Current State**: Limited API implementation
|
||||
**Django Styleguide Recommendation**: Structured API with proper serializers
|
||||
|
||||
**Issues Identified**:
|
||||
- Minimal DRF usage despite having REST framework installed
|
||||
- API endpoints mixed with HTML views
|
||||
- No clear API versioning strategy
|
||||
|
||||
### ⚠️ Environment Variable Management
|
||||
**Current State**: Hard-coded configuration values
|
||||
**Django Styleguide Recommendation**: Environment-based configuration with `django-environ`
|
||||
|
||||
**Issues Identified**:
|
||||
```python
|
||||
# Current problematic patterns in settings.py
|
||||
SECRET_KEY = "django-insecure-=0)^0#h#k$0@$8$ys=^$0#h#k$0@$8$ys=^" # Hard-coded
|
||||
DEBUG = True # Hard-coded
|
||||
DATABASES = {
|
||||
"default": {
|
||||
"NAME": "thrillwiki",
|
||||
"USER": "wiki",
|
||||
"PASSWORD": "thrillwiki", # Hard-coded credentials
|
||||
"HOST": "192.168.86.3", # Hard-coded host
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
- Proper authentication backends
|
||||
- SSL redirect configuration
|
||||

|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### ✅ Performance Strengths
|
||||
- Query optimization with `select_related`/`prefetch_related`
|
||||
- Caching implementation in services
|
||||
- Efficient database queries in adapters
|
||||
- HTMX for reduced page loads
|
||||
|
||||
### ⚠️ Performance Areas
|
||||
- Could benefit from more aggressive caching
|
||||
- Some N+1 query patterns in views
|
||||
- Large template rendering without fragments
|
||||
|
||||
## Recommendations
|
||||
|
||||
### High Priority
|
||||
1. **Restructure Settings**: Implement environment-based settings structure
|
||||
2. **Environment Variables**: Use `django-environ` for all configuration
|
||||
3. **Security**: Remove hard-coded secrets and credentials
|
||||
4. **Selectors**: Implement proper selectors pattern for data retrieval
|
||||
|
||||
### Medium Priority
|
||||
1. **API Structure**: Implement proper DRF API with versioning
|
||||
2. **Testing**: Add factory_boy for test data generation
|
||||
3. **Query Optimization**: Review and optimize database queries
|
||||
4. **Documentation**: Add API documentation with DRF spectacular
|
||||
|
||||
### Low Priority
|
||||
1. **Template Fragments**: Break down large templates into smaller components
|
||||
2. **Service Decomposition**: Further break down large services
|
||||
3. **Caching Strategy**: Implement more comprehensive caching
|
||||
4. **Type Hints**: Complete type annotation coverage
|
||||
|
||||
## Conclusion
|
||||
|
||||
The ThrillWiki project demonstrates strong understanding and implementation of Django best practices, particularly in model architecture, service layer design, and template organization. The project's use of advanced features like `pghistory` for audit trails and HTMX for dynamic updates shows sophisticated Django development.
|
||||
|
||||
The main areas requiring attention are settings organization, environment configuration, and security hardening. These are common issues in Django projects and relatively straightforward to address.
|
||||
|
||||
The project is well-positioned for production deployment with the recommended improvements, and already exceeds many Django projects in terms of architectural decisions and code organization.
|
||||
