I have two classes : Letter and LetterFiles (attached files to the letter):

  
Class  Letter  extends  DataObject  {  
     private static $db = array (
    	 'Sender' => 'Text',
	 'SendTo' => 'Text',
……		
  );
  private static $has_many = array (
  	'Letters' => 'LetterFiles'  );
	);
……
}

Class  LetterFiles  extends  File {  
     private  static  $has_one = array (
  	'Files' => 'Letter'
  );
.........
  }

  

I want to show all letters and all attached files on LetterPage:

class  LetterPage  extends  Page {
	private $db = array();
}

class  LetterPage_Controller  extends Page_Controller {
       public function index () {
      $letters = Letter::get()->sort('DateUpload');
      return array (
			'AllLetters' => $letters
			);

}

I want to use template LetterPage.ss:

<% loop $AllLetters %>
            <tr>
                …….
                <td>$Sender</td>
                <td>$SendTo</td>    
                <td>$Theme</td>
                <td>
                      <% loop $Files %>
                          $Name
                      <% end_loop %>

                </td>
                
            </tr>                    
<% end_loop %>

But it doesn't render attached files.
Please, give me any ideas.
