How do I get the UUID of a bundle?

Question

The getBundleInfo method returns only the machine name and label for bundles. How do I get the UUID of each bundle, or of all bundles?

Answer 1

<?php

namespace Drupal\uuid\Controller;

use Drupal\Core\Controller\ControllerBase;
use Drupal\Core\Entity\ContentEntityType;
use Symfony\Component\HttpFoundation\JsonResponse;

/**
 * Class UUIDController.
 *
 * @package Drupal\uuid\Controller
 */
class UUIDController extends ControllerBase {

  public function uuidGet() {
    $uuid = [];
    $entity_type_definations = \Drupal::entityTypeManager()->getDefinitions();
    /* @var $definition \Drupal\Core\Entity\EntityTypeInterface */
    foreach ($entity_type_definations as $definition) {
      if ($definition instanceof ContentEntityType) {
        $content_types = \Drupal::entityManager()->getBundleInfo($definition->id());
        $entity_type = $definition->getBundleEntityType();
        if ($entity_type && $content_types) {
          foreach ($content_types as $type_id => $type) {
            $uuid[$entity_type][$type_id] = \Drupal::entityTypeManager()->getStorage($entity_type)->load($type_id)->uuid();
          }
        }
      }
    }
    return new JsonResponse($uuid);
  }

}

Above code will give UUID of all bundles and you can call this controller anywhere in your code like below, this will give all UUID's for bundles presented.

Drupal\entity_type_clone\Controller\UUIDController::uuidGet()

To get a single UUID for specific bundle try below code:

Drupal::entityTypeManager()->getStorage("ENTITY_TYPE")->load("BUNDLE_MACHINE_NAME")->uuid();

Answer 2

Replace BUNDLE_MACHINE_NAME with your bundle machine name.

Drupal::entityTypeManager()->getStorage("node_type")->load("BUNDLE_MACHINE_NAME")->uuid();

Or you can also load it like this:

Drupal\node\Entity\NodeType::load("BUNDLE_MACHINE_NAME")->uuid();

Entities based on EntityInterface will have the uuid() method.

See EntityInterface::uuid

Answer 3

The easiest method will be by adding UUID by editing views of entity listing.

Eg: if you want to find the UUID of content,

1. Edit the view admin/content
2. Add Field UUID
3. Save View

Navigate to admin/content to see uuid for corresponding content entity

Answer 4

If you have devel module installed, you can see the UUID by inspecting the development output of such content from the admin UI or debugging a variable.
