嘿伙计们我有接下来的两个实体:
class CarInqueritoExtraFields
{
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* @var DbaCustomFields
*
* @ORM\ManyToOne(targetEntity="DbaCustomFields", inversedBy="inqueritoExtraFields")
* @ORM\JoinColumns({
* @ORM\JoinColumn(name="id_custom_field", referencedColumnName="id", onUpdate="cascade", onDelete="cascade", nullable = false)
* })
*/
private $idCustomField;
}
class DbaCustomFields
{
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* @ORM\OneToMany(targetEntity="CarInqueritoExtraFields", mappedBy="idCustomField", cascade={"persist"})
*/
private $inqueritoExtraFields;
/**
* @var integer $idContacto
*
* @ORM\Column(name="nome", type="string", nullable=true)
*/
private $nome;
}
这两个实体都有获取/设置。 我的DbaCustomFieldsRepository中有以下方法:
public function getCustomFieldsNotUsed($idInquerito) {
$qb = $this->getEntityManager()->createQueryBuilder();
$qb2 = $this->getEntityManager()->createQueryBuilder();
$qb->select('cf')
->from('CareAdminBundle:DbaCustomFields', 'cf')
->where($qb->expr()->notIn('cf.id', $qb2->select('ief.idCustomField')
->from('CareAdminBundle:CarInqueritoExtraFields', 'ief')
->where('ief.idInquerito = :idInquerito')
->getDQL()))
->setParameter('idInquerito', $idInquerito);
return $qb;
}
我在formBuilder中获得$ qb:
public function buildForm(FormBuilder $builder, array $options){
$id_inquerito = $this->id_inquerito;
$builder->add('idCustomField', 'entity', array(
'empty_value' => 'Escolha um campo',
'class' => 'Care\AdminBundle\Entity\DbaCustomFields',
'required' => false,
'query_builder' => function(\Care\AdminBundle\Repository\DbaCustomFieldsRepository $repository) use ($id_inquerito){
return $repository->getCustomFieldsNotUsed($id_inquerito);
}));
}
但我得到了这个错误,但我无法弄清楚原因:
在渲染模板期间抛出异常(“[语义错误]第0行,第80行'idCustomField'附近:错误: 无效的PathExpression。必须是StateFieldPathExpression。“)in :: base.html.twig第19行。
我认为问题应该在我的QueryBuilder中,但我不知道为什么.. 任何帮助表示赞赏! 谢谢:)
----------------------------------的更新 ----- ---------------------------------------- 我设法得到解决方案,也许不是正确的方法,但它确实有效。 问题出在querybuilder上,所以我这样做了:
//First i pick the CarInqueritoExtraFields By IdInquerito and save the idCustomField from the retrieved object in a array.
$em = $this->getEntityManager();
$carInqueritoExtraFieldsByIdInquerito = $em->getRepository('CareAdminBundle:CarInqueritoExtraFields')->findByIdInquerito($idInquerito);
$arrayExtraFields = array();
foreach ($carInqueritoExtraFieldsByIdInquerito as $extraField) {
array_push($arrayExtraFields, $extraField->getIdCustomField()->getId());
}
//Then this:
$qb->select('cf')
->from('CareAdminBundle:DbaCustomFields', 'cf')
->where($qb->expr()->notIn('cf.id', $arrayExtraFields));
如果有人有更好的方法,请随时告诉我:)

你正在尝试嵌套查询构建器,这是完全无效的Doctrine。改为使用连接。
