Symfony2 FOSUserBundle用户实体字段覆盖

I have a problem with overriding an entity. I need the field emailCanonical to be not be unique.

我有覆盖实体的问题。我需要字段emailCanonical不是唯一的。

Here is what I've done: In my UserBundle\Resources\config\doctrine\User.orm.xml I've added the following attribute-overrides configuration, according to the Doctrine2 documentation

以下是我所做的：在我的UserBundle \ Resources \ config \ doctrine \ User.orm.xml中，我根据Doctrine2文档添加了以下属性覆盖配置

<attribute-overrides>
    <attribute-override name="emailCanonical">
        <field column="email_canonical" unique="false" name="emailCanonical" />
    </attribute-override>
</attribute-overrides>

Then I ran the following console commands

然后我运行了以下控制台命令

$ php app/console doctrine:migrations:diff
$ php app/console doctrine:migrations:migrate

Everything worked fine. emailCanonical was made non unique. But now, when I need to generate an entity in other bundles of project, I have a strange error:

一切都很好。 emailCanonical不是唯一的。但是现在，当我需要在其他项目包中生成一个实体时，我有一个奇怪的错误：

 $ php app/console doctrine:generate:entities SkyModelsBundle:Category
 Generating entity "Sky\Bundle\ModelsBundle\Entity\Category"

 [Doctrine\ORM\Mapping\MappingException]
 Invalid field override named 'emailCanonical' for class 'Sky\Bundle\UserBundle\Entity\User'.

 doctrine:generate:entities [--path="..."] [--no-backup] name

However, if I remove the override settings from xml mapping, everything works fine.

但是，如果我从xml映射中删除覆盖设置，一切正常。

You override using PHP annotations like so (This is supported starting from doctrine version 2.3 and above, please note that in the documentation it mentions that you cannot override types , however I was able to do so using the latest version of doctrine , at the time of writing it is 2.4.4):

你可以使用像这样的PHP注释覆盖（从doctrine 2.3及更高版本开始支持这一点，请注意在文档中它提到你不能覆盖类型，但是我能够使用最新版本的doctrine，当时写它是2.4.4）：

<?php 
namespace Namespace\UserBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use FOS\UserBundle\Model\User as BaseUser;

/**
 * User
 * @ORM\Entity
 * @ORM\AttributeOverrides({
 *     @ORM\AttributeOverride(name="id",
 *          column=@ORM\Column(
 *              name     = "guest_id",
 *              type     = "integer",
 *              length   = 140
 *          )
 *      )
 * })
 */
class myUser extends BaseUser
{
    /**
     * @ORM\Id()
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;
}

This is specified in the documentation at: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/inheritance-mapping.html#overrides

这在以下文档中指定：http：//docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/inheritance-mapping.html#overrides

#2

Quote from official documentation, so may be its the only way.

从官方文档引用，所以可能是唯一的方法。

If you need to change the mapping (for instance to adapt the field names to a legacy database), the only solution is to write the whole mapping again without inheriting the mapping from the mapped superclass.

如果您需要更改映射（例如，使字段名称适应旧数据库），唯一的解决方案是再次编写整个映射而不继承映射超类的映射。

#3

I believe the name attribute of the field tag is not required, since it is already specified for the attribute-override tag

我相信字段标记的name属性不是必需的，因为它已经为attribute-override标记指定

Try this

尝试这个

<attribute-overrides>
    <attribute-override name="emailCanonical">
        <field column="email_canonical" unique="false" />
    </attribute-override>
</attribute-overrides>

It seems that FOSUserBundle entities aren't imported correctly into your project. Make sure FOSUserBundle is present in "mappings" section ("doctrine" branch) of your config.yml

似乎FOSUserBundle实体未正确导入到您的项目中。确保config.yml的“mappings”部分（“doctrine”分支）中存在FOSUserBundle

doctrine:
    orm:
        entity_managers:
            default:
                connection:       default
                mappings:
                    AcmeDemoBundle: ~
                    FOSUserBundle: ~

Got the same bug just now, and I solved it. Doctrine throws this Mappingexception in ClassMetadataInfo when it cannot find the related property (attribute or relation) in its mapping.

刚刚得到了同样的bug，我解决了它。当Doctrine在其映射中找不到相关属性（属性或关系）时，它会在ClassMetadataInfo中抛出此Mappingexception。

So, in order to override "emailCanonical" attribute, you need to use "attribute-overrides" and "attribute-override" (as you did), and redefine php class property in your entity :

因此，为了覆盖“emailCanonical”属性，您需要使用“attribute-overrides”和“attribute-override”（就像您所做的那样），并在您的实体中重新定义php类属性：

<?php
...
class YourUser extends BaseUser
{
    ...
    /**
     * Email canonical
     *
     * @var string
     *
     * @ORM\Column(name="email_canonical", type="string", length=255, unique=false)
     */
    protected $emailCanonical;

@EDIT : using this solution causes me another bug.

@EDIT：使用此解决方案会导致另一个错误。

It solved the one about "Invalid field override named…", but I got another one with "Duplicate definition of column…" when trying to validate schema with php app/console doctrine:schema:validate command.

它解决了一个关于“无效字段覆盖命名...”的问题，但是当我尝试使用php app / console doctrine：schema：validate命令验证模式时，我得到另一个“列重复定义...”。

Any idea ?

任何想法 ？

Your class that extends BaseUser should be like this:

扩展BaseUser的类应该是这样的：

<?php 
namespace Namespace\UserBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use FOS\UserBundle\Model\User as BaseUser;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
 * User
 * @ORM\Entity
 * @ORM\Table(name="user")
 * @UniqueEntity(fields="email", message="your costum error message")
 *
 */
class myUser extends BaseUser
{
    /**
     * @ORM\Id()
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;
}

?>

I know this is an old post, but i found a solution, at least it worked for me, maybe it would be helpful for someone else.

我知道这是一个老帖子，但我找到了一个解决方案，至少它对我有用，也许对其他人有帮助。

Well, i had the same issue and i'm using a custom manager for the fos_user, in the declaration file config.yml under doctrine entity_manager custom manager i declared the mapping to FOS_userBundle, BUT what was missing is to tell FOS_user that we use a diffrent manager and that's by adding :

好吧，我有同样的问题，我正在使用fos_user的自定义管理器，在doctrine entity_manager自定义管理器下的声明文件config.yml中我声明了映射到FOS_userBundle，但是缺少的是告诉FOS_user我们使用了不同的经理，这是通过添加：

fos_user:
---- db_driver: orm
---- model_manager_name: MyCustom_Manager

fos_user：---- db_driver：orm ---- model_manager_name：MyCustom_Manager
