在一对多/多对多中保持链接 - Doctrine and Symfony2

Question

我有一个使用用户和帐户实体的多对多。我需要在关联表中添加一个 isOwner 字段，因此我将其更改为一对多/多对一关系。以下是我的 3 个实体（用户、帐户、用户帐户）。

当我持久化用户时，用户记录和帐户记录都添加了，但关联记录没有。我也不确定如何在保留用户的同时设置 isOwner 字段。

有谁知道如何保存关联记录？是否应该自动添加关联记录？

用户：

/**
 * xxx\CoreBundle\Entity\User
 *
 * @ORM\Table(name="user")
 * @ORM\Entity
 */
class User implements UserInterface
{
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;

    /**
     * @var string $firstName
     *
     * @ORM\Column(name="firstName", type="string", length=255, nullable=false)
     * @Assert\NotBlank()
     */
    private $firstName;

    /**
     * @var Account
     *
     * @ORM\OneToMany(targetEntity="UserAccount", mappedBy="user", cascade={"persist"})
     */
    private $account;

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

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

    /**
     * Set firstName
     *
     * @param string $firstName
     */
    public function setFirstName($firstName)
    {
        $this->firstName = $firstName;
    }

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

    /**
     * Add account
     *
     * @param xxx\CoreBundle\Entity\Account $account
     */
    public function addAccount(\xxx\CoreBundle\Entity\Account $account)
    {
        $this->account[] = $account;
    }

    /**
     * Get account

帐号：

    }

    }

    /**

}

控制器：

$account = new Account();
$account->setName('Test account');

$user = new User();
$user->setFirstName('John');
$user->addAccount($account);

$manager->persist($user);
$manager->flush();

Answer 1

您正在尝试将帐户保留为 UserAccount 实体。试试这个：

$account = new Account();
$account->setName('Test account');

$user = new User();
$user->setFirstName('John');

$user_account = new UserAccount();
$user_account->setAccount($account);
$user_account->setUser($user);

$manager->persist($user);
$manager->flush();
