## Acceptance Criteria
- [ ] has_one association is created automatically
- [ ] Foreign key is properly configured
- [ ] Association name is consistent and predictable
- [ ] Association supports lazy loading
- [x] has_one association is created automatically
- [x] Foreign key is properly configured
- [x] Association name is consistent and predictable
## Implementation Plan
1. Analyze existing implementation in generate_aux_model_class method
2. Verify has_one association is properly configured with correct foreign key
3. Ensure association name follows consistent naming convention
4. Update task documentation to mark completion
## Implementation Notes
The has_one association was already implemented in the generate_aux_model_class method in task-3. The implementation correctly:
- Creates has_one association automatically when aux_table is defined
- Uses proper foreign key configuration based on base STI class (e.g., vehicle_id for Vehicle STI)
- Follows consistent naming convention using table_name.to_s.singularize.to_sym
- Supports lazy loading as standard ActiveRecord has_one associations do
The association is set up in lines 158-162 of lib/active_record/aux_table.rb:
```ruby
T.unsafe(self).has_one(
table_name.to_s.singularize.to_sym,
class_name: class_name,
foreign_key: "#{base_class_name}_id"
)
```
All tests pass and the implementation meets all acceptance criteria.
