在实体表单字段中创建查询

Question

我需要获取国家/地区列表,按字母顺序排序.由于我将实体翻译成四种语言(英语,法语,西班牙语和中文),我使用了gedmo学说扩展来管理翻译.问题是当我在实体表单字段类型中获取此列表时:

$form = $builder->add('country', 'entity', 
array('class' => 'GroupCommonBundle:Country',
      'query_builder' => function(EntityRepository $er) {
                  $query = $er->createQueryBuilder('c')->orderBy('c.name');
       }

结果按原始实体定义(英语)而非当前语言环境(西班牙语或法语)排序,我真正需要的是什么.其实我用的$this->container->getParameter('locale')

我试图迫使查询钩,如解释在这里:

$query->getQuery()->setHint(\Gedmo\Translatable\TranslatableListener::HINT_TRANSLATABLE_LOCALE, $this->container->getParameter('locale'));

但是AFAIK,这只有在查询写成dql时才有效:

    $query = $this->getDoctrine()->getManager()->createQuery('
            SELECT c
            FROM GroupCommonBundle:Country c
            ORDER BY c.name ASC');
    $query->setHint(\Gedmo\Translatable\TranslatableListener::HINT_TRANSLATABLE_LOCALE, $this->container->getParameter('locale'));

实体表单不允许这样做,因为它正在等待queryBuilder对象.

所以,我需要翻译我的收藏并以他当前的语言排序.谁知道如何实现这一目标？

我遇到了和你一样的问题.我不知道是否有更好的解决方案来解决问题,但它对我有用.解决方案是覆盖实体表单类型.

forms.xml

<service id="acme.form.type.entity" class="Acme\AcmeBundle\Form\Type\EntityType">
    <tag name="form.type" alias="entity" />
    <argument type="service" id="doctrine" />
</service>

EntityType.php

<?php

namespace Acme\AcmeBundle\Form\Type;

use Doctrine\Common\Persistence\ObjectManager;
use Symfony\Bridge\Doctrine\Form\Type\DoctrineType;

use Acme\AcmeBundle\Doctrine\Form\ChoiceList\ORMQueryBuilderLoader;

class EntityType extends DoctrineType
{
   public function getLoader(ObjectManager $manager, $queryBuilder, $class)
   {
      return new ORMQueryBuilderLoader($queryBuilder, $manager, $class);
   }

   public function getName()
   {
      return 'entity';
   }
}

ORMQueryBuilderLoader.php

namespace Acme\AcmeBundle\Doctrine\Form\ChoiceList;

use Symfony\Bridge\Doctrine\Form\ChoiceList\ORMQueryBuilderLoader as BaseORMQueryBuilderLoader;

class ORMQueryBuilderLoader extends BaseORMQueryBuilderLoader
{
    private $queryBuilder;

    public function __construct($queryBuilder, $manager = null, $class = null)
    {
        parent::__construct($queryBuilder, $manager, $class);

        $this->queryBuilder = $queryBuilder($manager->getRepository($class));
    }

    public function getEntities()
    {
        $query = $this->queryBuilder->getQuery();

        $query->setHint(
            \Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER,
            'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker'
        );

        return $query->execute();
    }
}

希望能帮助到你.
