Belongs_to or has_many

2 tables Items and Categories

Categories (id, name)
Items (id, name, category_id)

Category_id can be null, and there are Categories that has not an Item.

Any chance of taking this list moderated?

Well you may not realise it yet, but the fact that having a
category_id on the items table and no other columns on the categories
table works for you means that you have already solved this problem:
the belongs_to always lives on the table with the foreign key and the
has_many or has_one on the other side.
