Question

Ive a HABTM relationship where the output is like below, what i would like to do is have cakephp return a “list” with just the “friend.id” and “friend.company_name” and exclude the “User”.

Ive spent quite a while researching how to do this and cant get it to work.

My “search method” in users controller; i think i need to use the containable behaviour but im not sure what to do. ive managed to get the “friend” results only show 2 fields but i need to get rid of the “User” results. How do i do this?

The relationship is defined as in the user model file;

var $hasAndBelongsToMany = array(
'Friend' => array(
    'joinTable' => 'retailerrelationships',
    'className' => 'User',
    'foreignKey' => 'retailer_id',
    'associationForeignKey' => 'supplier_id'
)
    );

user action in user controller:

$this->User->Behaviors->attach('Containable');

$users=$this->User->find('all',array('conditions'=>array('User.id'=>$this->Auth->user('id')),'contain'=>array('Friend.id','Friend.company_name')));         
        $this->set('users' ,$users); 

debug Output

                (

Answer 1

You should look at the Set class.

Try this

Set::combine($results, '{n}.Friend.id', '{n}.Friend.company_name');
