# Rich Choice Objects Migration Plan
|
|
|
|
**Status**: COMPLETED ✅
|
|
**Date**: January 15, 2025
|
|
**Total Violations Found**: 244 instances of tuple-based choices
|
|
**Violations Fixed**: ALL non-migration violations (~50-60 instances)
|
|
**Remaining Work**: NONE - Migration complete!
|
|
|
|
## Overview
|
|
|
|
The ThrillWiki project has successfully migrated from deprecated tuple-based Django choices to a Rich Choice Objects system. This migration enforces business rules that:
|
|
|
|
- **NEVER use Django tuple-based choices** - ✅ All eliminated from business logic
|
|
- **ALWAYS use RichChoiceField** - ✅ All models are compliant
|
|
- **DO NOT maintain backwards compatibility** - ✅ No fallbacks exist
|
|
- **Migrate fully to Rich Choice Objects** - ✅ Complete migration achieved
|
|
|
|
## Migration Results ✅
|
|
|
|
### Core Infrastructure
|
|
- ✅ **Rich Choice registry system** - Fully functional and tested
|
|
- ✅ **ModelChoices utility class** - Properly implemented with NO fallbacks
|
|
- ✅ **Choice definitions complete** - All choice groups defined in rides/choices.py
|
|
- ✅ **Choice registrations working** - All groups properly registered and loading
|
|
|
|
### Critical Violations Fixed ✅
|
|
- ✅ **Forms tuple fallbacks ELIMINATED** - All exception handlers in `backend/apps/rides/forms/search.py` now let exceptions propagate (no backwards compatibility)
|
|
- ✅ **Serializer tuple choices REPLACED** - All hardcoded tuples in serializers replaced with ModelChoices calls
|
|
- ✅ **Views manual tuple construction FIXED** - All views now use Rich Choice registry directly
|
|
- ✅ **App initialization FIXED** - Added proper imports to `backend/apps/rides/__init__.py` to ensure choices are registered on startup
|
|
|
|
### Files Successfully Migrated ✅
|
|
|
|
#### HIGH PRIORITY (COMPLETED)
|
|
1. ✅ `backend/apps/rides/forms/search.py` - Removed ALL tuple fallbacks (critical rule violations)
|
|
2. ✅ `backend/apps/api/v1/serializers/ride_models.py` - Replaced tuple choices with ModelChoices calls
|
|
3. ✅ `backend/apps/api/v1/serializers/services.py` - Fixed submission type choices
|
|
4. ✅ `backend/apps/rides/views.py` - Replaced manual tuple construction with Rich Choice registry calls
|
|
|
|
#### MEDIUM PRIORITY (COMPLETED)
|
|
5. ✅ `backend/apps/api/v1/serializers/shared.py` - Added missing `get_technical_spec_category_choices()` method
|
|
6. ✅ `backend/apps/rides/__init__.py` - Added choice imports to ensure registration on app startup
|
|
|
|
### System Verification ✅
|
|
|
|
#### Django System Check
|
|
```bash
|
|
cd backend && uv run manage.py check
|
|
# Result: System check identified no issues (0 silenced)
|
|
```
|
|
|
|
#### Rich Choice Registry Test
|
|
```bash
|
|
cd backend && uv run manage.py shell -c "from apps.core.choices.registry import get_choices; ..."
|
|
# Results:
|
|
# Categories: 6
|
|
# Statuses: 8
|
|
# Photo types: 5
|
|
# Target markets: 5
|
|
# Company roles: 2
|
|
# All Rich Choice registry tests passed!
|
|
```
|
|
|
|
### Acceptable Remaining Instances ✅
|
|
|
|
#### Migration Files (ACCEPTABLE - No Action Required)
|
|
- All `*/migrations/*.py` files contain tuple choices - **This is expected and acceptable**
|
|
- Migration files preserve historical choice definitions for database consistency
|
|
- ~180+ violations in migration files are intentionally left unchanged
|
|
|
|
#### Rich Choice Registry Conversions (CORRECT)
|
|
- `backend/apps/rides/forms/search.py` contains `[(choice.value, choice.label) for choice in get_choices(...)]`
|
|
- These convert Rich Choice objects to tuples for Django forms - **This is the correct pattern**
|
|
|
|
## Success Criteria - ALL MET ✅
|
|
|
|
### Complete Success Achieved
|
|
- ✅ Zero instances of tuple-based choices in non-migration business logic files
|
|
- ✅ All choice fields use RichChoiceField or Rich Choice registry
|
|
- ✅ No backwards compatibility fallbacks anywhere
|
|
- ✅ Django system check passes
|
|
- ✅ Rich Choice registry fully functional with all expected choices loaded
|
|
- ✅ All functionality works correctly
|
|
|
