Relationships with #Embedded column - symfony

Question

I have #Embeddable class for id:
/**
* #ORM\Embeddable()
*/
final class Id
{
/**
* #ORM\Id()
* #ORM\Column(type="string")
*/
private $id;
//getters, setters, etc
}
And two classes that have #ManyToOne relationship:
/**
* #ORM\Entity()
*/
final class Gist
{
/**
* #var Id
*
* #ORM\Id()
* #ORM\Embedded(class="App\Entity\Id")
*/
private $id;
/**
* #var User
*
* #ORM\ManyToOne(targetEntity="App\Entity\User")
*/
private $user;
//getters, setters, etc
}
And User class:
/**
* #ORM\Entity()
*/
final class User implements UserInterface
{
/**
* #var Id
*
* #ORM\Embedded(class="App\Entity\Id")
*
*/
private $id;
//getters, setters, etc
}
When I trying to create schema I got error: No mapping found for field 'id' on class 'App\Entity\User'.. What I'm doing wrong?

Answer 1

There no solution. https://github.com/doctrine/doctrine2/issues/7094.
Support of identifiers within #Embeddable is not really there yet, sorry.

Answer 2

I suggest not to use #Embeddable on id field. Cause it won't work. Declare your id field normally and it should work.
/**
* #ORM\Entity()
*/
class Gist
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
/**
* #var User
*
* #ORM\ManyToOne(targetEntity="App\Entity\User")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
private $user;
//getters, setters, etc
}
/**
* #ORM\Entity()
*/
class User implements UserInterface
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
//getters, setters, etc
}
Also your Many-To-One relation is bad, see: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/association-mapping.html#many-to-one-unidirectional
And never declare entities as final classes, see: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/architecture.html#entities
