我HAVA关系多到许多与产品实体和功能实体 产品实体:Doctrine2更新许多一对多关系
/**
* @ORM\ManyToMany(targetEntity="Feature")
* @ORM\JoinTable(name="Product_Feature",
* joinColumns={@ORM\JoinColumn(name="Product_id", referencedColumnName="id")},
* inverseJoinColumns={@ORM\JoinColumn(name="Feature_id", referencedColumnName="id")}
* )
*/
private $features;
功能实体:
/**
* @ORM\ManyToMany(targetEntity="Product", mappedBy="features")
* @ORM\OrderBy({"position" = "ASC"})
*/
private $products;
ProductRepository.php:
public function updateFeatures($id, $featuresIds)
{
return $this->getEntityManager()->createQueryBuilder()
->update('TestCatalogBundle:Product', 'p')
->set('p.features', ':features')
->where('p.id = :id')
->setParameter('features', $featuresIds)
->setParameter('id', $id)
->getQuery()
->getResult();
}
但是,当我打电话updateFeatures我得到错误:
features = :features': Error: Invalid PathExpression. StateFieldPathExpression or SingleValuedAssociationField expected
如何更新Product_Feature表?此外,我无法通过产品ID删除Product_Feature中的所有功能。
我改变了我的下一路控制器:
$em = $this->getDoctrine()->getEntityManager();
$features = $em->getRepository('TestCatalogBundle:Feature')->findBy(array('id' => $featureIds));
$product = $em->getRepository('TestCatalogBundle:Product')->find($id);
$product->getFeatures()->clear();
foreach ($features as $feature) {
$product->addFeature($feature);
}
$em->persist($product);
$em->flush();
但是,如果使用本地的SQL我需要2个查询,删除功能,并插入新的功能。但在这里我需要2个选择查询。也许我让这个任务错了?
