主义和Symfony2 ManyToMany：关联指不存在错误的反面

Question

Im trying to establish a many to many relationship between two Entities All I need is the exact same code that is documented here: http://docs.doctrine-project.org/en/latest/reference/association-mapping.html#many-to-many-bidirectional

here is the example code in case you don't want to open the link

<?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();
    }

    // ...
}

Here is my code:

//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();
    }
}

It triggers this error:

The association Gabriel\\UploadBundle\\Entity\\Image#imageowner refers to the inverse side field Gabriel\\UserBundle\\Entity\\User#ownedimage which does not exist.

I have been searching for hours I would appreciate if someone had an idea

Answer 1

Why a ManyToMany relationship. For me it's a OneToMany relationship.
