class FriendsController extends AppController 
{
/**

    public $components = array('Paginator');
    function index()
    {

    }
 function friendlist($user_id)
         {
                    $session_user_id = $this->Session->read('Auth.User.id');
                    if($user_id == $session_user_id )
                    {
                        $user_to = $session_user_id ;
                    }
                    else
                    {
                        $user_to = $user_id;
                    }
                    $this->Friend->find('all',array('Friend.user_to'=>$user_to,'Friend.status'=>'Accepted');
         }
function add_friend ( $id )
{
    if(!empty($this->data))
    {
        $this->Friend->Create();
        if($this->Friend->save($this->data))
        {
            $this->Session->setFlash('Friendship Requested');
            $this->redirect(array('controller'=>'users','action'=>'login'));

    function accept_friendship ( $id )
             {
            $this->Friend->id = $id;
            $current_status = $this->Friend->field('status');
            if($current_status=='Requested') {
                $this->Application->saveField('status', 'Accepted');
            }
            $this->Session->setFlash('Friendship Accepted');
            $this->redirect(array('controller'=>'friends','action'=>'index'));
        }
