If it were one to one then there could only be one equipment object for each type, that is what one to one means. Have a look at the Rails Guide on ActiveRecord Associations for a good introduction to the association types. I would avoid the use of the word equipment for the table name. It does not read well. Normally the table name should be the plural of the objects in the table. equipment_item might be better, then you can have one equipment items or two equipment_items.
