Symfony:Sonata用户和我的bundle实体之间的许多关系

我试图在Sonata的用户和我包中的一个名为“网络”的实体之间建立一种多人关系

其想法是通过SonataAdmin的用户创建/版本，能够为每个用户分配多个网络

以下是我得到的：

用户实体：

<?php
namespace Application\Sonata\UserBundle\Entity;

use Sonata\UserBundle\Entity\BaseUser as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

class User extends BaseUser
{
    /**
     * @var integer $id
     */
    protected $id;

    /**
     * @ORM\ManyToMany(targetEntity="\Acme\TestBundle\Entity\Network", mappedBy="users", cascade={"persist", "remove"})
     */
    protected $networks;

    public function __construct()
    {
        parent::__construct();
        $this->networks = new ArrayCollection();
    }

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

    /**
     * Add network
     *
     * @param \Acme\TestBundle\Entity\Network $network
     * @return User
     */
    public function addNetwork($network)
    {
        $this->networks[] = $network;

        $network->addUser($this);

        return $this;
    }

    /**
     * Remove network
     *
     * @param \Acme\TestBundle\Entity\Network $network
     */
    public function removeNetwork($network)
    {
        $this->networks->removeElement($network);

        $network->removeUser($this);
    }

    /**
     * Get networks
     *
     * @return \Doctrine\Common\Collections\ArrayCollection
     */
    public function getNetworks()
    {
        return $this->networks;
    }
}

<?php
namespace Acme\TestBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

/**
* @ORM\Entity
*/
class Network
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

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

    /**
     * @ORM\ManyToMany(targetEntity="\Application\Sonata\UserBundle\Entity\User", inversedBy="networks")
     * @ORM\JoinTable(name="Networks_Users")
     */
    protected $users;

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

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

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

    /**
     * Set name
     *
     * @param string $name
     * @return Network
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

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

    /**
     * Add user
     *
     * @param \Application\Sonata\UserBundle\Entity\User $user
     * @return Network
     */
    public function addUser($user)
    {
        $this->users[] = $user;

        return $this;
    }

    /**
     * Remove user
     *
     * @param \Application\Sonata\UserBundle\Entity\User $user
     */
    public function removeUser($user)
    {
        $this->users->removeElement($user);
    }

    /**
     * Get users
     *
     * @return \Doctrine\Common\Collections\ArrayCollection
     */
    public function getUsers()
    {
        return $this->users;
    }
}

<?php
namespace Acme\TestBundle\Admin;

use Sonata\UserBundle\Admin\Model\UserAdmin as SonataUserAdmin;

class UserAdmin extends SonataUserAdmin
{
    /**
     * {@inheritdoc}
     */
    protected function configureFormFields(\Sonata\AdminBundle\Form\FormMapper $formMapper)
    {
        parent::configureFormFields($formMapper);

        $formMapper
            ->with('Networks')
            ->add('networks', 'sonata_type_model', array(
                'by_reference' => false,
                'required' => false,
                'expanded' => false,
                'multiple' => true,
                'label' => 'Choose the user Networks',
                'class' => 'AcmeTestBundle:Network'
            ))
            ->end();
    }
}

用户管理类：

<?php
namespace Application\Sonata\UserBundle\Entity;

use Sonata\UserBundle\Entity\BaseUser as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

class User extends BaseUser
{
    /**
     * @var integer $id
     */
    protected $id;

    /**
     * @ORM\ManyToMany(targetEntity="\Acme\TestBundle\Entity\Network", mappedBy="users", cascade={"persist", "remove"})
     */
    protected $networks;

    public function __construct()
    {
        parent::__construct();
        $this->networks = new ArrayCollection();
    }

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

    /**
     * Add network
     *
     * @param \Acme\TestBundle\Entity\Network $network

     */
    public function addNetwork($network)
    {
        $this->networks[] = $network;

        $network->addUser($this);

        return $this;
    }

    /**

     *
     * @param \Acme\TestBundle\Entity\Network $network
     */
    public function removeNetwork($network)
    {
        $this->networks->removeElement($network);

        $network->removeUser($this);
    }

    /**
     * Get networks
     *
     * @return \Doctrine\Common\Collections\ArrayCollection
     */
    public function getNetworks()
    {
        return $this->networks;
    }
}

<?php
namespace Acme\TestBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

/**

class Network
{
    /**

    /**

     */
    protected $users;

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

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

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

    /**
     * Set name
     *
     * @param string $name
     * @return Network
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

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

    /**
     * Add user
     *
     * @param \Application\Sonata\UserBundle\Entity\User $user
     * @return Network
     */
    public function addUser($user)
    {
        $this->users[] = $user;

        return $this;
    }

    /**
     * Remove user
     *
     * @param \Application\Sonata\UserBundle\Entity\User $user
     */
    public function removeUser($user)
    {
        $this->users->removeElement($user);
    }

    /**
     * Get users
     *
     * @return \Doctrine\Common\Collections\ArrayCollection
     */
    public function getUsers()
    {
        return $this->users;
    }
}

<?php
namespace Acme\TestBundle\Admin;

use Sonata\UserBundle\Admin\Model\UserAdmin as SonataUserAdmin;

class UserAdmin extends SonataUserAdmin
{
    /**
     * {@inheritdoc}
     */
    protected function configureFormFields(\Sonata\AdminBundle\Form\FormMapper $formMapper)
    {
        parent::configureFormFields($formMapper);

        $formMapper
            ->with('Networks')
            ->add('networks', 'sonata_type_model', array(
                'by_reference' => false,
                'required' => false,
                'expanded' => false,
                'multiple' => true,
                'label' => 'Choose the user Networks',
                'class' => 'AcmeTestBundle:Network'
            ))
            ->end();
    }
}

如果我尝试从网络端管理用户，一切正常（没有添加或更改实际代码）：

Update-Profiler正在为条令显示以下消息：
Acme\TestBundle\Entity\Network:关联Acme\TestBundle\Entity\Network#用户指的是不存在的反向侧字段应用程序\Sonata\UserBundle\Entity\User#网络。
我找到了解决方案！您只需编辑文件
Application/Sonata/UserBundle/Resources/config/doctor/User.orm.xml
，并以xml格式添加关系列：
