The annotation "@OneToMany" in property was never imported (Doctrine2)

Question

I'm working with Doctrine 2 as an ORM for Slim 3 but I keep getting stuck in the object mapping section when I try to implement a bidirectional relationship

/**
 * Class Resource
 * @package App
 * @ORM\Entity
 * @ORM\Table(name="users", uniqueConstraints={@ORM\UniqueConstraint(name="user_id", columns={"user_id"})}))
 */
class User
{
    /**
     * @ORM\ManyToOne(targetEntity="UserRoles", inversedBy="users")
     * @ORM\JoinColumn(name="role_id", referencedColumnName="user_role_id")
     */
    protected $user_role;
}

/**
 * Class Resource
 * @package App
 * @ORM\Entity
 * @ORM\Table(name="user_roles", uniqueConstraints={@ORM\UniqueConstraint(name="user_role_id", columns={"user_role_id"})}))
 */
class UserRoles
{
    /**
     * @ORM\OneToMany(targetEntity="User", mappedBy="user_role")
     */
    protected $users;

    public function __construct()
    {
        $this->users = new ArrayCollection();
    }
}

I get an exception when I try php vendor/bin/doctrine orm:schema-tool:update --force

The output is:

[Doctrine\Common\Annotations\AnnotationException][Semantical Error] The annotation "@OneToMany" in property App\Entity\UserRoles::$users was never imported. Did you maybe forget to add a "use" statement for this annotation?

I have removed the setters and the getters and respective fields due to stackoverflow constraint of code to text ratio — clifford_owino, Sep 27 '16 at 09:26
It is "@ORM\OneToMany". See your `use` statements for details. — Alex Blex, Sep 27 '16 at 09:27
What @AlexBlex said. You are also missing ``@ORM\`` for ``ManyToOne`` and ``JoinColumn`` — Vladimir Cvetic, Sep 27 '16 at 09:29
i have `use Doctrine\ORM\Mapping as ORM;` on the users class — clifford_owino, Sep 27 '16 at 09:29

Doctrine classes like

Column
Entity
JoinColumn
ManyToMany
ManyToOne
OneToMany
OneToOne
Full list available on Github

are part of the Doctrine\ORM\Mapping namespace.

You should import this namespace with ORM as an alias. Then you should add @ORM in front of these classes as annotation to make them work.

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\ManyToOne(...)
 * @ORM\JoinColumn(...)
 */

If you just want to use every single of those classes you have to import each separately.

use Doctrine\ORM\Mapping\ManyToOne;
use Doctrine\ORM\Mapping\JoinColumn;

/**
 * @ManyToOne(...)
 * @JoinColumn(...)
 */

So your question == solution? – danopz Sep 27 '16 at 09:33
Do you have the use statement on top of your Entitys? – danopz Sep 27 '16 at 09:37
yes i have and the error now is `[Doctrine\Common\Annotations\AnnotationException] [Semantical Error] The annotation "@Column" in property App\Entity\User::$c reated was never imported. Did you maybe forget to add a "use" statement fo r this annotation?` – clifford_owino Sep 27 '16 at 09:40
Column is in the same namespace i mentioned above, add an additional `ORM` in front of this and other similar propertys. – danopz Sep 27 '16 at 09:42
this is how i'm using the `Column` class `@ORM\Column(name="user_id", type="integer")` – clifford_owino Sep 27 '16 at 09:45
