Récupération champ dans la vue

Bonjour,
Voici un debug de ma page accueil

array(
    'posts' => array(
        (int) 0 => array(
            'Post' => array(
                'id' => '6',
                'name' => 'Mon premier article',
                'slug' => 'mon-premier-article',
                'content' => '<p>Lorem ipsum</p>',
                'type' => 'post',
                'online' => '1',
                'category_id' => '1',
                'user_id' => '1'
                'media_id' => '14',
                'thumb' => 'articles/2012/06/prga_velo_6_i.jpg',
                'thumbf' => 'articles/2012/06/prga_velo_6_i_%dx%d.jpg',
                'link' => array(
                    'controller' => 'posts',
                    'action' => 'show',
                    'id' => '6',
                    'slug' => 'mon-premier-article'
                )
            ),
            'Category' => array(
                'id' => '1',
                'name' => 'Vélo',
                'slug' => 'velo',
                'icon' => '',
                'post_count' => '1',
                'link' => array(
                    'controller' => 'posts',
                    'action' => 'category',
                    'slug' => 'velo'
                )
            ),
            'Thumb' => array(
                'id' => '14',
                'ref' => 'Post',
                'ref_id' => '6',
                'file' => 'articles/2012/06/prga_velo_6_i.jpg',
                'position' => '0',
                'filef' => 'articles/2012/06/prga_velo_6_i_%dx%d.jpg'
            )
        )
    )
)

Voici le foreach de ma vue :

<?php foreach ($posts as $k => $v): $v = current($v); ?>
    <a href="<?php echo $this->Html->url($v'link']); ?>">
    <div class="grid3">
            <?php echo $this->Html->image(sprintf($v'thumbf'],220,113)); ?>
        <h3><?php echo substr($v'name'],0,20); ?></h3>
    </div>
    </a>
<?php endforeach; ?>

Voici mon controller :

$this->loadModel('Post');
$this->Post->contain('Thumb','Category');
$d'posts'] = $this->Post->find('all',array(
    'conditions' => array('type'=>'post','online'=>1),
    'order' => 'Post.created DESC', 
    'limit' => 4
));
$this->set($d);

Comment faites vous pour récupérer dans le foreach le nom de la catégorie associée à mon article, par exemple içi Vélo.
Merci
