Question

我有两个具有ManyToMany关系的实体（学生，通知），我想向多个学生插入通知，我使用SonataAdmin管理应用程序这是我的代码：实体学生：

<?php 
namespace App\BlogBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**

/**

实体通知：

<?php

namespace App\BlogBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
* Notification
*
* @ORM\Table(name="notification")
* @ORM\Entity
*/
class Notification {
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var string
 *
 * @ORM\Column(name="message", type="string", length=255)
 */
private $message;

/**
 *@ORM\ManyToOne(targetEntity="Etudiant",inversedBy="notification")
 *@ORM\JoinColumn(name="etudiant_id",referencedColumnName="id")
 */
private $etudiant;

/**
 * Get id
 *
 * @return integer 
 */
public function getId()
{
    return $this->id;
}

/**
 * Set message
 *
 * @param string $message
 * @return Notification
 */
public function setMessage($message)
{
    $this->message = $message;

    return $this;
}

/**
 * Get message
 *
 * @return string 
 */
public function getMessage()
{
    return $this->message;
}

/**
 * Set etudiant
 *
 * @param \App\BlogBundle\Entity\Etudiant $etudiant
 * @return Notification
 */
public function setEtudiant(\App\BlogBundle\Entity\Etudiant $etudiant = null)
{
    $this->etudiant = $etudiant;

    return $this;
}

/**
 * Get etudiant
 *
 * @return \App\BlogBundle\Entity\Etudiant 
 */
public function getEtudiant()
{
    return $this->etudiant;
}

public function __toString() {
    return $this->message;
}
}

错误是：

类型错误：传递给App \ BlogBundle \ Entity \ Notification :: setEtudiant（）的参数1必须是App \ BlogBundle \ Entity \ Etudiant的实例，Doctrine \ Common \ Collections \ ArrayCollection的实例，在/ var中调用第556行/www/html/School/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php

Answer 1

如错误所述，您的setEtudiant定义错误。它应该以Doctrine Collection作为参数而不是Etudiant实例。

在字段Symfony中插入多个选项
