我参照诗人的demo写了这个例子，但是不显示分页器和评论框？评论框要另外写代码加入吗？请指点一下，谢谢了。

function og_views_callback_page() { 
	$output = '';
    $query = db_select('node','n')->extend('PagerDefault');
    $query->leftJoin('field_data_body', 'b', 'n.nid = b.entity_id');
    $query->fields('n',array('nid','title','created'))->fields('b',array('body_summary'));
    $query->condition('n.status', 1)
        ->condition('n.type', 'group')
        ->limit(1);
    $query->orderBy('n.created', 'DESC');
    $objects = $query->execute()->fetchAll();
    $rows = array();
    foreach ($objects as $key=>$object) {
        $row = array();
        $row['gid'] = $object -> nid;
        $row['title'] = l($object -> title, 'groups/'.$object ->nid);
        $row['description'] = $object->body_summary;
        $row['created'] = $object -> created;
        $rows[] = $row;
    }
    $output .= theme ( 'pager' );
    $output .= theme('grouds', array('rows' => $rows));
    $output .= theme ( 'pager' );
    return $output;
}

tpl文件：

<ul>
<?php foreach($rows as $data){?>
<li class="list">
		<div class="title"><?php print $data['title']?></div>
  <?php print $data['description']?>
  <div class="created"><?php print $data['created']?></div>
	</li>
<?php }?>
</ul>
