You can use an exclusion clause. See:

http://guides.rubyonrails.org/active_record_validations_callbacks.html#exclusion

It uses an array, which in your case would just be [0]. There might
be a way to do just a single value, I don't know offhand, never had
to. Let us know if you find something like that....
