An object relationship with different objects in model

Hello, I have a question and want to know the best way to solve it.

I have 3 models:

  CREATE TABLE IF NOT EXISTS `homes` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `createAt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
 `modifiedAt` timestamp NULL DEFAULT NULL,
 `type` varchar(50) NOT NULL COMMENT 'Casa mata, piso, chalet, adosado, duplex, etc..',
 `alias` varchar(50) DEFAULT NULL,
 `rental` tinyint(1) NOT NULL DEFAULT '0' COMMENT 'Si está para alquilar o no',
 `description` text,
 `terrace` int(11) DEFAULT NULL COMMENT 'metros de terraza',
 `parking` int(11) DEFAULT NULL COMMENT 'nº parkings',
 `storage` tinyint(1) DEFAULT NULL,
 `garden` tinyint(1) DEFAULT NULL,
 `restroom` smallint(6) DEFAULT NULL,
 `bedsrooms` smallint(6) DEFAULT NULL,
 `size` smallint(6) DEFAULT NULL COMMENT 'metros totales',
 `energy_rating` varchar(1) DEFAULT NULL,
 `floors` smallint(3) DEFAULT NULL,
 `active` tinyint(1) DEFAULT '1',
 `communityId` int(11) DEFAULT NULL,
 PRIMARY KEY (`id`),
 UNIQUE KEY `id` (`id`),
 KEY `communityId` (`communityId`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=41 ;

CREATE TABLE IF NOT EXISTS `incidences` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `createAt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `modifiedAt` timestamp NULL DEFAULT NULL,
  `for` varchar(50) NOT NULL,
  `forId` int(11) NOT NULL,
  `userId` int(11) NOT NULL,
  `name` varchar(50) NOT NULL,
  `description` text,
  `date` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
  `state` smallint(6) NOT NULL,
  PRIMARY KEY (`id`),
  KEY `userId` (`userId`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=32 ;

CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(100) NOT NULL,
  `surname` varchar(100) DEFAULT NULL,
  `email` varchar(255) NOT NULL,
  `password` char(60) NOT NULL,
  `mustChangePassword` char(1) DEFAULT NULL,
  `profilesId` int(10) unsigned NOT NULL,
  `banned` char(1) NOT NULL,
  `suspended` char(1) NOT NULL,
  `active` char(1) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `profilesId` (`profilesId`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=29 ;

In my models to link users with incidents (the owner)

$this->hasMany('id',
        __NAMESPACE__ . '\Incidences',
        'userId',
        array(
            'alias' => 'incidences',
    ));

An incident can be a home or other object. So I have two fields to identify who it is, "for" the object regards the incidence and "FORID" id.

How I can make the relationship between home and incidence in the model? Is there any way? Something like this?

$this->belongsTo(array('id',''),
        'Incidences',
        array('id','Homes'),
        array(
            'alias' => 'incidences')
    );

I solved it by a specific function for this, but I wonder if there is another "smarter" way.

class Homes extends Model {
...
  public static function getIncidences($id){
      return parent::find(array(
          "[for] = ?0 and [forId] = ?1",
          'bind' => array(
              0 => 'Homes',
              1 => $id
          )
      ));
  }
 ... 
 }

Thanks :)
