Invalid field override named 'email'

Question

I am trying to override two properties of FOSUserBundle's User mapping.

use FOS\UserBundle\Model\User as BaseUser;
...
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;

/**
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 * @ORM\Table(name="user")
 * @UniqueEntity(
 *     fields={"emailCanonical", "zone"},
 *     errorPath="email",
 *     message="This email address is already in use."
 * )
 * @ORM\AttributeOverrides({
 *     @ORM\AttributeOverride(name="email", column=@ORM\Column(type="string", name="email", length=255, unique=false, nullable=false)),
 *     @ORM\AttributeOverride(name="emailCanonical", column=@ORM\Column(type="string", name="emailCanonical", length=255, unique=false, nullable=false))
 * })
 */
class User extends BaseUser
{
    ...

Everything seems to be working fine, except when I generate accessors: Invalid field override named 'email'

The error is thrown here:

// Doctrine\ORM\Mapping\ClassMetadataInfo

public function setAttributeOverride($fieldName, array $overrideMapping)
{
    if ( ! isset($this->fieldMappings[$fieldName])) {
        throw MappingException::invalidOverrideFieldName($this->name, $fieldName);
    }

Here, $this->fieldMappings only contains the fields of my child User and not of the parent (mapped superclass).

Anyone got a clue?

Answer 1

The way I managed to fix this issue with Invalid field override named [field] for class [class] was to also add the overwritten attribute in the class I overwritten it.

I'm using version Symfony v2.7.8 and Doctrine v1.6.1.

Example:

<?php

use FOS\UserBundle\Model\User as BaseUser;

/**
 * @ORM\Entity
 * @ORM\Table(name="user")
 *
 * @ORM\HasLifecycleCallbacks
 * @ORM\AttributeOverrides({
 *     @ORM\AttributeOverride(name="usernameCanonical",
 *         column=@ORM\Column(
 *             type="string",
 *             name="username_canonical",
 *             length=255,
 *             unique=false
 *         )
 *     )
 * })
 */
class User extends BaseUser
{
    /**
     * @var string
     *
     * @ORM\Column(type="string", name="username_canonical", length=255, unique=false)
     */
    protected $usernameCanonical;
    ...
}
