Question

我在Symfony 2中使用Knp Paginator Bundle。

在尝试将Doctrine查询传递给分页器时，我一直收到以下错误：

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，那么一切正常。即：

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

但据我所知，您应该能够传递查询本身甚至是查询构建器。此外，我想象这样，我得到的所有结果，而不只是一页。

ps：我正在使用paginator bundle的dev-master版本

Answer 1

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

“knplabs / knp-components”：“1.2.1”，

我认为当前版本有一个错误

至少现在它对我有用

Answer 2

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paginator可以分页：

阵列
学说\ ORM \查询
学说\ ORM \ QueryBuilder的
学说\ ODM \ MongoDB的\查询\查询
学说\ ODM \ MongoDB的\查询\生成器
Doctrine \ Common \ Collection \ ArrayCollection - 任何学说关系收集包括
ModelCriteria - 推动ORM查询
使用Solarium_Client和Solarium_Query_Select作为元素的数组

knp paginator仅适用于数组
