Re: create has many link

i'm trying to create it, but still can't work as expected.

Controller/AppController.php

class AppController extends Controller {

    public function beforeFilter() {

        $this->Auth->allow('index');

        $this->loadModel('Category');

        $this->set('categories', $this->Category->find('all', array('order' => 'Category.id ASC')));

    }

}

Controller/ProductsController.php

class ProductsController extends AppController {

public function category($category_id = null) {

$file = $this->Product->findAllByCategoryId($category_id);

$id = $file['Product']['id'];

$this->paginate = array('limit' => 10, 

'contain' => array('Comment' => array('fields' => array('COUNT(*) As count'))),

'order' => array('Product.id DESC'), 

'conditions' => array('Product.category_id' => $category_id, 'Product.is_active' => 'Y'));

$products = $this->Paginate('Product');

$this->set(compact('products'));

}

}

View/Layout/default.ctp

            <div id="leftcolumn">

          <ul>

          <?php foreach ($categories as $category): ?>

                        <li> <?php echo $this->Html->link(__($category['Category']['category']), array('controller' => 'products', 'action' => 'category', $category['Category']['id'])); ?> </li>

                    <?php endforeach; ?>

          </ul>

            </div>

any ideas, suggestions, or hints how to achieve this?

thanks and best regards
