KnpPaginatorBundle按左连接表的计数排序

Question

我的存储库类中有以下方法：

$dql = 'SELECT n.name, n.offer_url as url, COUNT(p) as clicks, COUNT(t) as conversions '
    . 'FROM AppThanatosBundle:Products n '
    . 'LEFT JOIN n.pixels p '
    . 'LEFT JOIN p.transactions t '
    . 'GROUP BY n.id ';

$query = $this->getEntityManager()
->createQuery($dql);

return $query;

我将它传递给我的控制器中的KnpPaginator Bundle：

$paginator  = $this->get('knp_paginator');
$pagination = $paginator->paginate(
    $products,
    $request->query->getInt('page', 1),
    15
);

如何按列排序：COUNT（p）作为点击次数

在我看来，我尝试使用n.clicks或p.clicks，如：

{{ knp_pagination_sortable(pagination, 'Clicks', 'n.clicks') }}

不幸的是，有一个错误：

There is no such field [clicks] in the given Query component, aliased by [p]
