DB_DataObject_Iterator

Hi everypearbody !
I've been using DB_dataObject in several sites now, most of
them  
using a templating system.
So I found it helpful to implement an Iterator to DBDO so
that I can  
use a regular loop to fetch my DBDO results in the
template.
You can find the php file in a compressed file here :
http:
//demental.info/DB_DataObject_Iterator.php

To use it you need MDB2 (does not work with DB), and PHP5
(for  
Iterator implementation).
This is an example DB_DataObject configuration to use it :

$options = array (  'database' => DB_URI,
                     'schema_location' =>
'your/schema/path',
                     'class_location' =>
'your/DOclasses/path',
                     'require_prefix' => 'DataObjects/',
                     'class_prefix' => 'DataObjects_',
                     'extends'
=>'DB_DataObject_Iterator',
                    
'extends_location'=>'path/to/DB/DataObject/ 
Iterator.php',
                     'db_driver'=>'MDB2',
                 );

And a short usage example using trivial articles and
comments tables  
(e.g. in a blog) :
<?php
$art = DB_DataObject::factory('articles');
$art->find();
// then you can for example assign it to a Smarty instance
:
$smarty->assign_by_ref('articles',$art);
?>

In a smarty template (or whatever templating engine), use it
with  
foreach :

{foreach from=$articles item=article}
<div id="article_{$article->id}">
<h3>{$article->title}</h3>
<p>{$article->body}</p>
<hr />
<dl><dt>Comments :</dt>
{foreach from=$articles->getComments() item=comment}
<dd>
	<span>From {$comment->author} on
{$comment->date}</span>
	{$comment->body}
</dd>
{/foreach}
</dl>
</div>
{/foreach}

Let me know if you find this stuff interesting !
