title: redirect deleted products from database asigning them a new ID
body: <p>I need to make some redirects for some products which has been deleted from database.</p>
  
  <p>I get the product from database this way:</p>
  
  <pre>
  
      public function show( $prod_id=null){
        $produs=Product::find(array('conditions' => array('product_id = ?', $prod_id)));
      }
  
  </pre>
  
  <p>and I want to create some kind of array with the ID's that are deleted and set them a new ID for an existing product.
  I have made something like this (1726 is the deleted ID and the other one, 369 is the new ID):</p>
  
  <pre>
  
      $products = array(  '1726' => 369,
                          '1716' => 1650,
               );
  
  </pre>
