Symfony2 SoftDeleteable 不适用于 QueryBuilder 删除-php问题

Symfony2 SoftDeleteable not working on QueryBuilder Delete(Symfony2 SoftDeleteable 不适用于 QueryBuilder 删除)

本文介绍了Symfony2 SoftDeleteable 不适用于 QueryBuilder 删除的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

Softdelete 行为在通过实体管理器执行删除语句时正常工作，如下代码:

Softdelete behavior works fine on execute delete statement via the entity manager as the following code:

$entity = $this->em->getRepository('Users')->find(7);
$this->em->remove($entity);
$this->em->flush();

但是当通过 QueryBuilder 执行相同的功能时，硬删除将在数据库上执行

but when execute the same functionality via QueryBuilder hard delete will execute on database

$qb = $this->em->createQueryBuilder();
$qb->delete('Users', 'p');
$qb->where($qb->expr()->eq('p.id', ':id'));
$qb->setParameters(array("id" => 7));
$result = $qb->getQuery()->getResult();

如何在所有情况下通过实体管理器或查询构建器允许软删除

How can I allow softdelete in all cases either via entity manager or query builder

推荐答案

如果您使用 DQL，那么您必须使用查询提示.这应该可以解决问题:

If you use DQL then you have to use a Query Hint. This should do the trick:

$query = $qb->getQuery()

$query->setHint(
    DoctrineORMQuery::HINT_CUSTOM_OUTPUT_WALKER,
    'GedmoSoftDeleteableQueryTreeWalkerSoftDeleteableWalker'
);

$result = $query->getResult();

更新:

文档提到您必须使用查询提示，但没有提供示例，因此我从他们的测试中提取了用法.

The docs mention that you have to use a Query Hint but don't provide an example so I pulled the usage from their tests.

文档:https://github.com/l3pp4rd/DoctrineExtensions/blob/master/doc/softdeleteable.md

测试用法:https://github.com/l3pp4rd/DoctrineExtensions/blob/master/tests/Gedmo/SoftDeleteable/SoftDeleteableEntityTest.php
