我試圖構建「編輯」控制器/視圖但我遇到這個錯誤。從我讀過它可能是一個分離問題，我試圖解決它，但我不知道它是什麼問題。它應該返回一個集合，但我甚至不知道「代理」意味着什麼以及它如何獲得它。Symfony2 - Doctrine2 - ManyToOne關係/預期論點類型「Doctrine Common Collections Collection」，「代理 ...實體...代理」給出
爲此我正在創建的編輯視圖的實體：
<?php
namespace Monse\WebBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Monse\WebBundle\Entity\BasedeDatos
*
* @ORM\Table()
* @ORM\Entity
*/
class BasedeDatos
{
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\ManyToOne(targetEntity="Monse\WebBundle\Entity\ServidoresBD")
* @ORM\JoinColumn(name="servidores_id", referencedColumnName="id",nullable=false)
*
*/
private $servidorBD;
/**
* @var string $nombreBD
*
* @ORM\Column(name="nombreBD", type="string", length=255,unique=true)
*/
private $nombreBD;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set servidorBD
*
* @param integer $servidorBD
*/
public function setServidorBD(\Monse\WebBundle\Entity\ServidoresBD $servidorBD)
{
$this->servidorBD = $servidorBD;
}
/**
* Get servidorBD
*
* @return integer
*/
public function getServidorBD()
{
return $this->servidorBD;
}
/**
* Set nombreBD
*
* @param string $nombreBD
*/
public function setNombreBD($nombreBD)
{
$this->nombreBD = $nombreBD;
}
/**
* Get nombreBD
*
* @return string
*/
public function getNombreBD()
{
return $this->nombreBD;
}
public function __construct()
{
$this->servidorBD = new Doctrine\Common\Collections\ArrayCollection();
}
}
FormType：
<?php
namespace Monse\WebBundle\Form;
use Doctrine\ORM\EntityRepository;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
class BasedeDatosType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('ServidorBD','entity',
array ('class' => 'MonseWebBundle:ServidoresBD',
'multiple' => true,
'required' => true,
'label' => 'Servidor de Base de Datos: ',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('u')
->orderBy('u.url', 'ASC');
},
))
->add('nombreBD','text', array('required' => true, 'label' => 'Nombre Base de Datos: '))
->add('UsuarioBD','entity',array('class' => 'MonseWebBundle:UsuariosBD','multiple' => true,
'required' => true, 'label' => 'Usuario Asociado: ',
'property_path' => false,
'query_builder' => function (EntityRepository $er){
return $er->createQueryBuilder('s')
->orderBy ('s.usuario','ASC'); },))
;
}
public function getName()
{
return 'basededatos';
}
}
負責的問題（我認爲）的實體：
<?php
namespace Monse\WebBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Monse\WebBundle\Entity\ServidoresBD
*
* @ORM\Table()
* @ORM\Entity
*/
class ServidoresBD
{
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string $url
*
* @ORM\Column(name="url", type="string", length=255)
*/
private $url;
/**
*
* @ORM\OneToOne (targetEntity="Monse\WebBundle\Entity\Dominios")
* @ORM\JoinColumn(name="dominio_id", referencedColumnName="id",nullable=false,unique=true)
*/
private $dominio;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set dominio
*
* @param integer $dominio
*/
public function setDominio(\Monse\WebBundle\Entity\Dominios $dominio)
{
$this->dominio = $dominio;
}
/**
* Get dominio
*
* @return integer
*/
public function getDominio()
{
return $this->dominio;
}
/**
* Set url
*
* @param string $url
*/
public function setUrl($url)
{
$this->url = $url;
}
/**
* Get url
*
* @return string
*/
public function getUrl()
{
return $this->url;
}
public function __toString()
{
return $this->getUrl();
}
}
表格類型：
<?php
namespace Monse\WebBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
class ServidoresBDType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('url')
->add('dominio', 'collection', array('type' => new DominiosType()));
;
}
public function getDefaultOptions(array $options)
{
return array(
'data_class' => 'Monse\WebBundle\Entity\ServidoresBD'
);
}
public function getName()
{
return 'issue_selector';
}
}
我應該在哪裏添加arraycollection來返回？我如何防止這種情況再次發生？我很抱歉，如果這是一個愚蠢的問題，我正在努力學習。
