Using a Custom Query for the Entities

If you need to specify a custom query to use when fetching the entities (e.g. you only want to return some entities, or need to order them), use the query_builder option. The easiest way to use the option is as follows:


use Doctrine\ORM\EntityRepository;
// ...

$builder->add('users', 'entity', array(
    'class' => 'AcmeHelloBundle:User',
    'query_builder' => function(EntityRepository $er) {
        return $er->createQueryBuilder('u')
            ->orderBy('u.username', 'ASC');
    },
));

您需要使用
property
attribute-

--或---


您可以省略
属性
属性,并将
\uuuu toString()
魔术方法添加到实体中。这样,您就可以更好地控制将用作选项标签的内容。

这对您有帮助吗?
