2c2a6c90f0 docs: Comprehensive Django migration audit and implementation plan
- Analyzed Supabase database schema (100+ tables)
- Reviewed Django implementation (~2,200 lines of models, ~3,700 lines of API)
- Catalogued 42 Edge Functions requiring migration
- Identified 325 frontend component files needing backend support
- Created 6-phase migration plan with timeline estimates
- Prioritized missing features by user impact
- Migration currently ~40% complete

Key Findings:
- Core entities (Parks, Rides, Companies) fully implemented
- Reviews, User Lists, Notifications systems not implemented
- 60+ database tables still needed
- Edge Functions need migration to Celery tasks
- Estimated 6-8 weeks for complete migration

## 7. Technical Debt & Architecture
### 7.1 What's Working Well ✅
1. **Clean Architecture**
- Separation of concerns (models, services, API endpoints)
- Generic versioning system using ContentType
- FSM-based moderation workflow
2. **Django Packages Used**
- `django-ninja`: Modern API framework (excellent choice)
- `django-fsm`: State machine for moderation
- `django-lifecycle`: Model lifecycle hooks
- `dirtyfields`: Track field changes
3. **Database Design**
- UUID primary keys
- Proper indexing
- JSON fields for flexibility
- PostGIS conditional support
4. **Code Quality**
- Well-documented models
- Type hints in API
- Consistent naming
### 7.2 Areas for Improvement ⚠️
1. **Empty Models**
- `apps/notifications/models.py` is essentially empty
- `apps/reviews/models.py` doesn't exist
2. **Missing Services**
- Need service layer for complex business logic
- Edge Function logic needs to be translated to services
3. **Testing**
- No Django tests found
- Need comprehensive test suite
4. **Background Tasks**
- Celery not yet configured
- All Edge Function logic currently synchronous
5. **Rate Limiting**
- Not implemented in Django yet
- Supabase has rate limiting tables
### 7.3 Recommended Architecture Changes
1. **Add Celery**
```
django/
celery.py # Celery app configuration
tasks/
__init__.py
notifications.py # Notification tasks
moderation.py # Moderation tasks
maintenance.py # Cleanup tasks
auth.py # Auth tasks
```
2. **Add Service Layer**
```
django/apps/*/services/
__init__.py
business_logic.py # Complex operations

## 8. Estimated Timeline
### Minimum Viable Migration (Core Features Only)
**Timeline**: 3-4 weeks
- Phase 1: Critical User Features (2 weeks)
- Phase 2: Enhanced Data (1 week)
- Phase 5: Background Tasks (1 week)
**Result**: Feature parity for 80% of users
### Complete Migration (All Features)
**Timeline**: 6-8 weeks
- Phase 1: Critical User Features (2 weeks)
- Phase 2: Enhanced Data (1 week)
- Phase 3: Moderation & Admin (1 week)
- Phase 4: Account & Compliance (4 days)
- Phase 5: Background Tasks (1 week)
- Phase 6: Content & Analytics (1 week)
- Testing & Polish (1 week)
**Result**: 100% feature parity with Supabase

## 9. Risk Assessment
### High Risk
1. **Notification System Migration**
- Currently using Novu (third-party service)
- Need to replace with Django + Celery + email/push provider
- Risk: Feature gap if not implemented properly
- Mitigation: Implement core notifications first, enhance later
2. **Background Task Migration**
- 42 Edge Functions to migrate
- Complex business logic in functions
- Risk: Missing functionality
- Mitigation: Systematic function-by-function migration
### Medium Risk
1. **Data Migration**
- No existing data (stated: "no data to be worried about")
- Risk: Low
2. **Frontend Integration**
- Frontend expects specific Supabase patterns
- Risk: API contract changes
- Mitigation: Maintain compatible API responses
### Low Risk
1. **Core Entity Models**
- Already implemented
- Well-tested architecture
2. **Authentication**
- Already implemented with JWT, OAuth, MFA
- Solid foundation
