cakephp foreign key not the primary key
===

I have a site developed in cakephp 2.0, I want to make a relation between two tables:

activity_ingredients
	1 	id 	int(10) UNSIGNED 	No 	None 	AUTO_INCREMENT 	
	2 	type_id 	tinyint(2) 	No 	None 		
	3 	activity_id 	int(11) 	No 	None 		
	4 	ingredient_id 	int(10) 	No 	None 		
	5 	created 	datetime 		
actions
	1       id 	int(10) UNSIGNED 	No 	None 	AUTO_INCREMENT 	
	2 	type_id 	tinyint(2) 	No 	None 		
	3 	language 	char(2)		No 	None 		
	4 	text 	varchar(100) 		No 	None 		
	5 	created 	datetime 	

I want to associate the two tables with the field "type_id".
I have done in this mode into my code:

   

     	class Action extends AppModel{
		public $name = 'Action'; //non utilizzata nel sito è il nome del modello alla fine per migliorare la compatibilità
		
		public $belongsTo = array(
			'ActivityIngredients' => array(
				'className'		=> 'ActivityIngredients',
				'conditions'	=> '',
				'order'			=> '',
				'foreignKey'	=> 'type_id'
			)
		);
		 
}
    
    class ActivityIngredients extends AppModel{
    		public $name = 'ActivityIngredients'; //non utilizzata nel sito è il nome del modello alla fine per migliorare la compatibilità
    		
    		public $belongsTo = array(
    			'Activity' => array(
    				'className'		=> 'Activity',
    				'conditions'	=> '',
    				'order'			=> '',
    				'foreignKey'	=> 'activity_id'
    			),
    			'Ingredient' => array(
    				'className'		=> 'Ingredient',
    				'conditions'	=> '',
    				'order'			=> '',
    				'foreignKey'	=> 'ingredient_id'
    			)
    		);
    
    		public $hasMany = array(
    			'Action' => array(
    				'className' => 'Action',
    				'conditions' => '',
    				'dependent' => true,
    				'foreignKey'   => 'type_id',
    				'associatedKey'   => 'type_id'
    			)
    		);
    	}

It doesn't retrieve the correct data.. It seems that It takes the id for the foreign key.
This is the view:

    <?php foreach ($user['Activity'] as $activities) {
    var_dump($activities);
    ?>
    	<div class="line-cnt"><div class="line">
    	</div>
    </div>
    <h2>Attività</h2>
    <div class="table">
    	<div>
    		<div>Activity created</div><div><?php echo $activities['created']; ?>
    		</div>
    	</div>
    	<div>
    		<div>Actions text</div><div><?php echo $activities['Action']['text']; ?></div>
    	</div>
    	<div>
    		<div>ActivityIngredient ingredient_id</div><div><?php echo $activities['ActivityIngredients']['ingredient_id']; ?></div>
    	</div>
    </div>
    <?php
    }
    ?>

The controller is a simple query with find all and recursive 3 into the User that is collegate with the tables

    $this->User->recursive = 3;
    		$user = $this->User->read();
    		
    		if (empty($username) || $username != $user['User']['username']) {
    			$this->redirect(array ('action'=>'view',$id,$user['User']['username']));
    		}
    		
    		$this->set('user', $user);

Help me please
