关于多对多关联的POST请求

我有两个具有多对多关联的实体:

class User extends BaseUser

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

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

    /**
     * @var string
     *
     * @ORM\Column(name="view", type="text")
     * @Assert\Choice(choices = {"work week", "week", "month", "year"}, message = "Choose a valid view.")
     */
    private $view;

    /**
     * @ManyToMany(targetEntity="AppBundle\Entity\User")
     * @JoinTable(name="calendars_publishers",
     *      joinColumns={@JoinColumn(name="calendar_id", referencedColumnName="id")},
     *      inverseJoinColumns={@JoinColumn(name="publisher_id", referencedColumnName="id", unique=true)}
     *      )
     */
    private $publishers;

    public function __construct()
    {
        $this->publishers = new \Doctrine\Common\Collections\ArrayCollection();
    }

    /**
      * Add publishers
      *
      * @param \AppBundle\Entity\User $publishers
      * @return Calendar
      */
      public function addPublisher(\AppBundle\Entity\User $publishers)
       {
          $this->publishers[] = $publishers;

           return $this;
       }

      /**
        * Remove publishers
        *
        * @param \AppBundle\Entity\User $publishers
        */
       public function removePublisher(\AppBundle\Entity\User $publishers)
     {
         $this->publishers->removeElement($publishers);
      }
}

当我使用正文对我的REST API(http://localhost:8000/calendars)发出POST请求时:

{
  "name": "My calendar",
  "view": "week",
  "publishers": [
    "/users/1",
    "/users/2"
  ]
}

我有回复:

{
  "@context": "/contexts/Calendar",
  "@id": "/calendars/3",
  "@type": "Calendar",
  "name": "My calendar",
  "view": "week",
  "publishers": []
}

所以,正如你所看到的,我的对象记录得很好,但我无法将一些用户放在publishers中。你有什么想法吗?

我使用捆绑包:

  • DunglasApiBundle
  • NelmioApiDocBundle
  • NelmioCorsBundle
  • FOSHttpCacheBundle
  • FOSUserBundle
  • LexikJWTAuthenticationBundle

2 个答案:

答案 0 :(得分:1)

您应该添加addPublisher(User $publisher)removePublisher(User $publisher)方法。

API平台在内部使用Symfony PropertyAccess组件,此组件需要此类方法才能访问私有属性。

听起来你应该在关系中指定fetch="EAGER",以便始终获取相关对象。
