If you were to use parent_id as the field name, which would be more conventional and arguably more intuitive, then topic.parent_id would give you the id and topic.parent would give you the object. As an aside I have found that when I find myself manipulating the ids then often it means I am not doing something the best way, not always but often. Very often rails can do a lot of the magic for me, removing the need to use the ids.
