Question

我试图在两个实体之间建立多对多的关系我只需要与此处记录的完全相同的代码： http://docs.doctrine-project.org/en/latest/reference/association-mapping.html#many-to-many-bidirectional

以下是您不想打开链接的示例代码

<?php
/** @Entity **/
class User
{
    // ...

    /**
     * @ManyToMany(targetEntity="Group", inversedBy="users")
     * @JoinTable(name="users_groups")
     **/
    private $groups;

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

    // ...
}

/** @Entity **/
class Group
{
    // ...
    /**
     * @ManyToMany(targetEntity="User", mappedBy="groups")
     **/
    private $users;

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

    // ...
}

这是我的代码：

//My User entity
namespace Gabriel\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;

class User extends BaseUser
{
    //...

    /**
     * @ORM\ManyToMany(targetEntity="Gabriel\UploadBundle\Entity\Image", mappedBy="imageowner")
     */
    protected $ownedimage;

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

    //...
}


//My Image entity

namespace Gabriel\UploadBundle\Entity;
use Doctrine\ORM\Mapping as ORM;

class Image
{
    /**
     * @ORM\ManyToMany(targetEntity="Gabriel\UserBundle\Entity\User", inversedBy="ownedimage")
     * @ORM\JoinTable(name="imageowner_ownedimage")
     */
    protected $imageowner;

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

它会触发此错误：

关联Gabriel \ UploadBundle \ Entity \ Image＃imageowner指的是反面字段Gabriel \ UserBundle \ Entity \ User＃ownedimage which 不存在。

我一直在寻找好几个小时如果有人有想法我会很感激

为什么是ManyToMany关系。对我而言，这是OneToMany的关系。

Doctrine和Symfony2 ManyToMany：Association指的是不存在错误的反面
