错误

您无法搜索关联字段 'My \ SampleBundle \ Entity \ Invitation#user'，因为它是反函数 关联的一面.查找方法仅在所有权方面起作用 协会. 500内部服务器错误-ORMException

You cannot search for the association field 'My\SampleBundle\Entity\Invitation#user', because it is the inverse side of an association. Find methods only work on owning side associations. 500 Internal Server Error - ORMException

我是刚刚执行文档的阶段.

I am the stage which just performed the documentation.

https://github.com/FriendsOfSymfony/FOSUserBundle /blob/master/Resources/doc/adding_invitation_registration.md

捆绑软件的显示是正常的.但是，如果我提交注册表，那将是一个错误.

The display of the bundle is normal. However, It has become an error if I submit registration form.

有帮助吗?

实际上，我一开始就设置了"inversedBy".
预先提问.
Symfony2 FOSUserBundle邀请:"inversedBy"映射错误
从表面上看，它确实起作用.但是，探查器会显示映射错误.

Actually, I had set up 'inversedBy' at first.
A pre-question.
Symfony2 FOSUserBundle Invitation : 'inversedBy' mapping errors
On the surface, it does work. However, mapping errors is displayed by profiler.

我的\ SampleBundle \ Entity \ Invitation#不包含必需的 "inversedBy"属性.

My\SampleBundle\Entity\Invitation# does not contain the required 'inversedBy' attribute.

因此，我根据建议进行了更改. 我不知道该怎么想.

so, I changed it in response to advice. I don't know what to think of it.

推荐答案

有解决方案.

There was solution.
https://github.com/FriendsOfSymfony/FOSUserBundle/issues/800

public function reverseTransform($value)
{
    // ...

    return $this->entityManager
        ->getRepository('My\SampleBundle\Entity\Invitation')
        ->findOneBy(array(
            'code' => $value,
            'user' => null,        <= Removing 'user' solves the issue
        ));
}
