Kohana ORM Aliasing and "Trying to get property of non-object"

Question

I have the following tables in the database:

• teams:
  • id
  • name
• matches:
  • id
  • team1_id
  • team2_id

I've defined the following ORM models in my Kohana v2.3.4 application:

class Match_Model extends ORM {
  protected $belongs_to = array('team1_id' => 'team', 'team2_id' => 'team');
}

class Team_Model extends ORM {
  protected $has_many = array('matches');
}

The following code in a controller:

$match = ORM::factory('match',1);
echo $match->team1_id->name; /* <-- */

Is throwing the following error on the linke marked with /* <--- */:

Trying to get property of non-object

The framework is yielding the value of the foreign key instead of a reference to a Match_Model instance as it should (giving the has_many and belongs_to properties stated).

Am I missing something?

Note: Just in case, I've added the irregular plural 'match' => 'matches' in application/config/inflector.php

SOLVED! The Kohana community gave me the answer:

The correct value for the $belongs_to property is:

class Match_Model extends ORM {
  protected $belongs_to = array('team1' => 'team', 'team2' => 'team');
}

The documentation states it:

class Blog_Post_Model extends ORM { 
    protected $belongs_to = array('author' => 'user', 'editor' => 'user'); 
}

The blog_posts database table would have 2 columns now, blog_posts.author_id and blog_posts.editor_id, and both would have values that exist in users.id.

It seems that I've missed that line, :)
