Looking through cake/libs/model/model.php I don't see anywhere in
saveAll where a check is done for a hasone association. (May have
missed it). I don't see how it could do this by default in any case.
It could recognize the hasone association but then how would it verify
uniqueness. It couldn't use the ID since that is unique for every
record. And it doesn't know which field to use to check uniqueness.
Since username should be unique I would say that you should add a
validate for isUnique for the username. This will prevent mulitiple
users with the same name and therefore enforce one profile per user.
in the User model add this:
var $validate = array(
'username' = => array(
'rule' => 'isUnique',
'message' => 'The user name has already been taken',
'required' => true));
