php - Modify name of item in cart -

i'm trying append string abc name of each item added cart. should show in cart/checkout , accessible programmatically.

so far, have overloaded mage_checkout_cartcontroller custom abc_def_cartcontroller such:

<frontend>     <routers>         <checkout>             <args>                 <modules>                     <abc_def before='mage_checkout'>abc_def</abc_def>                 </modules>             </args>         </checkout>     </routers> </frontend> 

new cartcontroller.php overloades addaction():

public function addaction(){     //prepare      $cart = $this->_getcart();     $params = $this->getrequest()->getparams();     $params['qty']=1;       try{         $product = $this->_initproduct();         $product->setdata('qty',1);          if(!$product){             //todo product not found             return;         }          $product->setdata('name',$product->getname()."abc");         $cart->addproduct($product,$params);         $cart->save();          $this->_getsession()->setcartwasupdated(true);         mage::dispatchevent('checkout_cart_add_product_complete',                 array('product' => $product, 'request' => $this->getrequest(), 'response' => $this->getresponse())             );        } catch (exception $e) {         //todo         mage::logexception($e);     }

by understanding, basic product information re-loaded database somewhere cannot figure or how make changes persistent. in advance.

i think better hook onto event sales_quote_item_set_product. event dispatched in mage_sales_model_quote_item::setproduct().
prior dispatching event there line:

->setname($product->getname())  

so assume can change name in custom observer event mentioned.
event receives parameters current quote item , product assigned it.
