This is what I would like to use:

#[ORM\Column(type: "string")]

instead of this:

/**
 *  @ORM\Column(type="string")
 */

But I'm getting this error:

(error: Class 'Column' is not annotated with 'Attribute' )

Is it because Doctrine does not support it yet, or am I missing something?

  • What use-case do you have for needing to use annotations like that? What are you trying to solve? – hppycoder Mar 23 '21 at 20:32

    In case you have hundreds of annotations and want to convert them attributes, you might prefer to automate this. I wrote an open-source tool Rector that handles this upgrade for you: https://getrector.org/blog/how-to-upgrade-annotations-to-attributes – Tomas Votruba Oct 13 '21 at 19:22

As @Seb33300 says, yes, it's now possible in Doctrine ORM 2.9. But for Symfony you need to do a little bit more than that. Here is a full list of steps to upgrade:

  1. Upgrade Doctrine ORM: "doctrine/orm": "^2.9".

  2. Upgrade Doctrine Bundle: "doctrine/doctrine-bundle": "^2.4".

  3. Set doctrine.orm.mappings.App.type: attribute (by default it's set to annotation):

    # config/packages/doctrine.yaml

doctrine:
  orm:
    mappings:
      App:
        type: attribute

  4. Apply similar changes to your entities:

    --- Dummy.php.old     Mon Jun 07 00:00:00 2021
+++ Dummy.php         Mon Jun 07 00:00:00 2021
@@ -7,15 +7,11 @@
 use App\Repository\DummyRepository;
 use Doctrine\ORM\Mapping as ORM;

-/**
- * @ORM\Entity(repositoryClass = DummyRepository::class)
- */
+#[ORM\Entity(repositoryClass: DummyRepository::class)]
 class Dummy
 {
-    /**
-     * @ORM\Id
-     * @ORM\GeneratedValue
-     * @ORM\Column(type = 'integer')
-     */
+    #[ORM\Id]
+    #[ORM\GeneratedValue]
+    #[ORM\Column(type: 'integer')]
     private $id;
 }

    The change from "annotation" to "attribute" is critical. Thank you for documenting it. – Jason Aller Jun 10 '21 at 01:06

    Is there any way to allow both, to have a smooth migration for the existing attributes? – the_nuts Apr 10 '22 at 16:51
  • @the_nuts Could you able to find a way to allow both ? Please let me know – nas Dec 15 '22 at 12:39

    @nas yes, I created another directory, so what I have in `Entity` is still with annotation, and what I have in `EntAttribs` (couldn't find a better name lol) is with attributes: https://pastebin.com/VS1jGD8x – the_nuts Dec 19 '22 at 14:16

EDIT: Doctrine 2.9 is now released with PHP 8 attributes support!

PHP 8 annotations have been merged in Doctrine ORM 2.9.x branch which is not released yet: https://github.com/doctrine/orm/pull/8266

Here is the documentation reference related to this feature: https://www.doctrine-project.org/projects/doctrine-orm/en/current/reference/attributes-reference.html
