這是我的實體示例代碼。Symfony2 @UniqueEntity自定義奏鳴曲管理類
EntityOne.php
//....
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
//....
/**
* EntityOne
*
* @ORM\Table()
* @ORM\Entity(repositoryClass="AppBundle\Entity\EntityOneRepository")
* @UniqueEntity(
* fields={"entityTwo", "number"},
* errorPath="number",
* message="A entityTwo with this number already exists."
*)
*/
class EntityOne
{
//....
/**
* @ORM\ManyToOne(targetEntity="EntityTwo", inversedBy="entityOne")
* @ORM\JoinColumn(name="entitytwo_id", referencedColumnName="id")
*/
protected $entityTwo;
/**
* @var integer
*
* @ORM\Column(name="number", type="integer")
*
* @Assert\NotBlank()
*/
private $number;
//....
}
EntityTwo.php
/**
* EntityTwo
*
* @ORM\Table()
* @ORM\Entity(repositoryClass="AppBundle\Entity\EntityTwoRepository")
*/
class EntityTwo
{
//....
/**
*
* @ORM\OneToMany(targetEntity="EntityOne", mappedBy="entityTwo", cascade={"persist"}, orphanRemoval=true)
* @ORM\OrderBy({"number" = "ASC"})
*/
protected $entityOne;
/**
* @var integer
*
* @ORM\Column(name="totals", type="integer")
*
* @Assert\NotBlank()
*/
private $totals;
//....
}
我使用SonataAdminBundle與定期管理類的實體的一切工作正常。
@UniqueEntity的問題在另一個地方。 在不同的管理員類中,創建一個EntityOne的記錄編號,該編號取決於EntityOne中某個字段的值。
要做到這一點,我做如下:
EntityTwoAdmin.php
class EntityTwoAdmin extends Admin {
//....
protected $formOptions = array(
'cascade_validation' => true
);
//....
public function preUpdate($entityTwo) {
$numTotals = $entityTwo->getTotals();
$numEntityOneExist = $entityTwo->getEntityOne()->count();
for ($i = $numEntityOneExist; $i <= $numTotals; $i++) {
$entityOneNew = new \AppBundle\Entity\EntityOne;
$entityOneNew->setNumber($i);
$entityTwo->addEntityOne($entityOneNew);
}
}
}
這裏記錄創建不考慮約束驗證。
我不知道我可能會丟失什麼,但肯定是我需要修復的。
有什麼想法?
