This is a really noob question but im having trouble finding the answer, is there a way in rails to have 0 or 1 association? For example, I create a user with no objects, than later on create an object for that user.

I tried using build with a 'has_one' association but that blew up... The only way I see this working is using 'has_many'. The user is suppose to only have at most one of these objects, is there any way to do this?
