我在 Symfony 2 中使用 Knp Paginator Bundle。

尝试将 Doctrine 查询传递给分页器时，我不断收到以下错误：

Fatal error: Call to a member function toArray() on a non-object in /var/www/adwind/vendor/knplabs/knp-components/src/Knp/Component/Pager/Event/Subscriber/Paginate/Doctrine/ORM/QuerySubscriber.php on line 67 Call Stack: 0.0000 635448 1. {main}() /var/www/adwind/web/app_dev.php:0 0.0166 6042728 2.

我正在使用 github 自述文件中的示例：

$em    = $this->get('doctrine.orm.entity_manager');
$dql   = "SELECT a FROM AdwindBannerBundle:Banner a";
$query = $em->createQuery($dql);
$pagination = $this->get('knp_paginator')->paginate($query,$page,10);

如果我传递结果数组而不是查询本身，一切正常。IE ：

$query = $em->createQuery($dql)->getResult();

但据我了解，您应该能够传递查询本身，甚至是查询生成器。我也想象这样我得到了所有的结果，而不仅仅是一页。

ps：我正在使用分页器包的 dev-master 版本

尝试在 composer.json 中使用特殊版本的 knp-сomponents

“knplabs/knp 组件”：“1.2.1”，

我认为当前版本有一个错误

至少现在它对我有用

这对我有用：

$em = $this->getDoctrine()->getEntityManager();
$query = $em->createQueryBuilder();

$query->select(array('b'))
        ->from('MyMainBundle:Customer', 'b')
        ->orderBy('b.updated_at', 'desc');

$paginator = $this->get('knp_paginator');
$requests = $paginator->paginate($query, 
                                $this->get('request')->query->get('page', 1), 5);

目前分页器可以分页：

  • 大批
  • 教义\ORM\查询
  • 教义\ORM\QueryBuilder
  • 教义\ODM\MongoDB\查询\查询
  • 教义\ODM\MongoDB\Query\Builder
  • Doctrine\Common\Collection\ArrayCollection - 任何学说关系集合，包括
  • ModelCriteria - 推进 ORM 查询
  • Solarium_Client 和 Solarium_Query_Select 作为元素的数组
