Symfony2 FOSUserBundle User entity field override - symfony

Question

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

Answer 1

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):
<?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

Answer 2

I believe the name attribute of the field tag is not required, since it is already specified for the attribute-override tag
Try this
<attribute-overrides>
<attribute-override name="emailCanonical">
<field column="email_canonical" unique="false" />
</attribute-override>
</attribute-overrides>

Answer 3

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

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
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.
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 :
<?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.
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.
Any idea ?

Your class that extends BaseUser should be like this:
<?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.
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 :
fos_user:
---- db_driver: orm
---- model_manager_name: MyCustom_Manager
