CodeIgniter / Datamapper：同一个表的两个一对多关系不起作用

Question

I'm having this problem with relationships with Codeigniter's DataMapper . I have an Interview model that has an author_id and an interviewee_id . They both relate to the user id in the user model.

I've been trying several approaches and none work; this is what I have right now:

class Interview extends DataMapper
{
  var $has_one = array(
    'interviewee' => array(
      'class' => 'user',
      'other_field' => 'done_interview'),
    'author' => array(
      'class' => 'user',
      'other_field' => 'written_interview') 
  );
}

class User extends DataMapper
{
  var $has_many = array(
    'done_interview' => array(
      'class' => 'interview',
      'other_field' => 'interviewee'),
    'written_interview' => array(
      'class' => 'interview',
      'other_field' => 'author') 
  );
}

How do I let DataMapper know that one relationship will go through author_id , and the other through interviewee_id ?

^{Quoting Nelo who answered his question in a comment:}

It seems there needs to be a user_id field necessarily and then for the other relationships I can name the fields however I want. So Changing interviewee_id to user_id seems to do the drill. Just in case someone has the same problem out there
