CodeIgniter DataMapper Problem with Relationship

Question

Hey i've got a pretty simple relationship in my Datamapper model..

in my model Ticket i hav:

var $has_one = array("user");

and when i try to

$ticket->user->get()->username;

it says:

DataMapper Error: 'ticket' is not a valid parent relationship for User. Are your relationships configured correctly?

i dont see the problem :/

What does your user model look like? Does it map back to the Ticket as well?

var $has_many = array("ticket");

must i hav this back link or is it optionally? – soupdiver May 11 '11 at 11:00
You need to link back as such because otherwise the mapper has no way to tell how many tickets a user has. Say for example all users submitted only 1 ticket. If the system tried to guess, the whole thing would fall apart when a single user submits two tickets. – onteria_ May 11 '11 at 11:06
