This commit introduces a complete refactoring of the variable product system:
1. **New Model**: ConfigurableKitOptionAttribute - M2M relationship between variants and attribute values
- Replaces TextField-based attribute storage with proper database relationships
- Ensures one value per attribute per variant through unique_together constraint
- Includes indexes on both option and attribute fields for query performance
2. **Form Refactoring**:
- Removed static 'attributes' field from ConfigurableKitOptionForm
- Added dynamic field generation in __init__ based on parent attributes
- Creates ModelChoiceField for each attribute (e.g., attribute_Длина, attribute_Упаковка)
- Enhanced BaseConfigurableKitOptionFormSet validation to check all attributes are filled
3. **View Updates**:
- Modified ConfigurableKitProductCreateView.form_valid() to save M2M relationships
- Modified ConfigurableKitProductUpdateView.form_valid() with same logic
- Uses transaction.atomic() for data consistency
4. **Template & JS Enhancements**:
- Reordered form so attributes section appears before variants
- Fixed template syntax: changed from field.name.startswith to "attribute_" in field.name
- Updated JavaScript to dynamically generate attribute select fields when adding variants
- Properly handles formset naming convention (options-{idx}-attribute_{name})
5. **Database Migrations**:
- Created migration 0005 to alter ConfigurableKitOption.attributes to JSONField (for future use)
- Created migration 0006 to add ConfigurableKitOptionAttribute model
6. **Tests**:
- Added test_configurable_simple.py for model/form verification
- Added test_workflow.py for complete end-to-end testing
- All tests passing successfully
Features:
✓ All attributes required for each variant if defined on parent
✓ One value per attribute per variant (unique_together constraint)
✓ One default variant per product (formset validation)
✓ Dynamic form field generation based on parent attributes
✓ Atomic transactions for multi-part operations
✓ Proper error messages per variant number
