多对多关联的 POST 请求 [英] POST request on many-to-many association

问题描述

我有两个具有多对多关联的实体:

I have two entities with a many-to-many association:

class User extends BaseUser

和

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);
      }
}

当我对 REST API 执行 POST 请求时(http://localhost:8000/calendars)与身体:

And when I do a POST request on my REST API (http://localhost:8000/calendars) with the body:

{
  "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，如您所见，我的对象记录得很好，但我无法将某些用户放入 publishers.你有什么想法吗?

So, as you see, my object is recorded well, but I cannot put some users in publishers. Do you have an idea?

我使用捆绑包:

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

使用 api-platform.

推荐答案

你应该添加 addPublisher(User $publisher) 和 removePublisher(User $publisher) 方法.

You should add addPublisher(User $publisher) and removePublisher(User $publisher) methods.

API Platform 内部使用了 Symfony PropertyAccess 组件，该组件需要这样的方法才能访问私有属性.

API Platform internally uses the Symfony PropertyAccess component, and this component requires such methods to be able to access to the private property.
