教义 Annontiation OneToOne，ManyToOne 等在 symfony 中不起作用

Question

这对我来说很奇怪。我正在使用symfony 3并尝试创建2个具有2个不同实体的表。两者都与ManyToOne相关联。清除缓存和更新策略后，这两个字段不会链接在一起。

所以我用 2 个相似的实体做了一个简单的一对一

用户：

'/**
* @ORMEntity
* @ORMTable(name="md_user")
* @ORMEntity(repositoryClass="AppBundleRepositoryUserRepository")
*/

 class User
{
/**
     * @ORMId
     * @ORMColumn(type="integer", unique=true)
     * @AssertNotBlank()
     * @ORMGeneratedValue(strategy="AUTO")
     */
    protected $id;
    /**
     * @ORMColumn(type = "integer")
     * @ORMOneToOne(targetEntity="Userdata")
     * @ORMJoinColumn(name="userdata_id", referencedColumnName="id")
     */
    protected $cid;'

用户数据：

    '/**
     * MdUser
     *
     * @ORMTable(name="md_userdata")
     * @ORMEntity(repositoryClass="AppBundleRepositoryUserdataRepository")

     */
    class  Userdata
    {
/**
* @var id
* @ORMColumn(type="integer")
* @ORMGeneratedValue(strategy="AUTO")
* @ORMId
* @ORMOneToOne(targetEntity="AppBundleEntityUser", inversedBy="cid")
*/
        protected $id;
        /**
         * @var string
         * @ORMColumn(name="last_name", type="string", length=255)
         */
        protected $last_name;
'

在symfony中更新了教义之后，没有任何变化。有人可以告诉我，我做错了什么吗？

添加了 config.yml：

似乎您有一个冲突的声明：不能同时自动生成列以及与另一个实体的关系。

因此，更改UserData的$id以反映这一点：删除自动生成，类似于这些行：

class  Userdata
{
    /**
    * @var id
    * @ORMColumn(type="integer")
    * @ORMOneToOne(targetEntity="AppBundleEntityUser", inversedBy="cid")
    */
    protected $id;
}

。但这并不是一个好的做法，因为无论如何您都需要一个唯一的 ID。所以我会走一条不同的路线，创建一个新字段来保存该特定关系。原始 ID 将自动生成，并且您为与 cid 的关系创建一个新字段。

PS ：同样，您在User上两次声明@ORMEntity。没什么大不了的，但你知道
