}

class Users extends ActiveRecord\Model {

    static $table_name = 'users';
    static $primary_key = 'user_id';

    static $has_many = array(
        array(
            'orgs_users',
            'class_name' => 'OrgsUsers',
            'primary_key' => 'user_id',
            'foreign_key' => 'user_id',
        ),
        array(
            'orgs',
            'class_name' => 'Orgs',
            'through' => 'orgs_users',
            'primary_key' => 'org_id',
            'foreign_key' => 'org_id',
        ),
    );

}

This just returns NULL

        $orgs = new Orgs;
        $org = $orgs->first()->users;

Any help would be appreciated and followed up by a nice donation to your coffee fund! :D
