我的实体:
/**
* @ORMManyToMany(targetEntity="Productgroup", inversedBy="fields")
* @ORMJoinColumn(name="productgroup", referencedColumnName="id")
*/
private $productgroup;
public function getProductgroup()
{
return $this->productgroup;
}
public function setProductgroup($productgroup): self
{
$this->productgroup = $productgroup;
return $this;
}
public function __construct()
{
$this->productgroup = new ArrayCollection();
}
这是输出:
array:2 [▼
0 => Fields {#7534 ▼
-id: 3
-name: "cat"
-unique_id: "5a38c820ed"
-productgroup: PersistentCollection {#7538 ▼

我正在尝试做的是删除所有与生产组 id 6
没有关系的数组。
到目前为止,我可以弄清楚如何删除所有与产品组 ID 6
没有关系的数组:
控制器:
$group = $this->getDoctrine()->getRepository($EntityName)->filterByColletion(6);
和存储库:
public function filterByColletion($id)
{
return $this->createQueryBuilder('f')
->leftJoin('f.productgroup', 'pg')
->where('pg.id = :id')
->setParameter(':id', 6)
->getQuery()
->execute();
}
结果是:
array:1 [▼
0 => Fields {#7534 ▼
-id: 3
-name: "cat"
-unique_id: "5a38c820ed"
-productgroup: PersistentCollection {#7538 ▼
-snapshot: array:1 [ …1]
-owner: Fields {#7534}
-association: array:20 [ …20]
-em: EntityManager {#2889 …11}
-backRefFieldName: "fields"
-typeClass: ClassMetadata {#6568 …}
-isDirty: false
#collection: ArrayCollection {#7539 ▼
-elements: array:1 [▼
0 => Productgroup {#7220 ▼
-id: 6
-name: "Animals"
-unique_id: "9e4ef1c46f"
-fields: PersistentCollection {#7431 ▶}
}
]
}
#initialized: true
}
-type: Type {#7615 ▼
+__isInitialized__: true
-id: 3
-name: "password"
-unique_id: "2ef6e55a1d"
-label: "password"
…2
}
}
]
但我需要它的方式恰恰相反。所以我尝试了:
public function filterByColletion($id)
{
return $this->createQueryBuilder('f')
->leftJoin('f.productgroup', 'pg')
->where('pg.id != :id')
->setParameter(':id', 6)
->getQuery()
->execute();
}
但这给了我一个空数组作为输出,而不是预期的名为 horse
的字段。
我也尝试了另一种方法,但这并没有奏效:
public function filterByColletion($id)
{
$em = $this->getEntityManager();
$qb = $this->_em->createQueryBuilder();
return $this->createQueryBuilder('f')
->leftJoin('f.productgroup', 'pg')
->where($qb->expr()->notIn('pg.id',6))
->getQuery()
->execute();
}
我相信
您不正确地使用 expr 尝试使用这种方式:
$qb->expr()->notIn('f.productgroup', [6])
