I have added private message module for one of my project which has it's own entity. I need to check whether the user is having access to that entity content or not. The module has it's menu item defined in the module's routing.yml


  path: '/private_messages/{private_message_thread}'
    _entity_view: 'private_message_thread'
    _title: 'Private Messages'
    _entity_access: 'private_message_thread.view'

How could I check whether the user has view access to the above menu path?

I have tested the entity access and $entity->access('view', $account); that worked in my case. I earlier used the optional $account parameter so that it could check the currently logged in user.

I loaded my entity with:

$entity_manager = \Drupal::entityTypeManager();
$thread_entity = $entity_manager->getStorage('private_message_thread')->load('private_message_thread_id');

I wanted to check whether the user has permission to view entity by code. Below is the code for the same I did in my case:

$account = \Drupal::currentUser();
$entity_manager = \Drupal::entityTypeManager();
$entity = $entity_manager->getStorage('private_message_thread')->load('private_message_thread_id');
$check = $entity->access('view', $account);

Please let me know if you have a better answer over the same.


You can check annotations of those entities and find access handler.


 * Defines the Private Message Thread entity.
 * @ContentEntityType(
 *   id = "private_message_thread",
 *   label = @Translation("Private Message Thread"),
 *   handlers = {
 *     "view_builder" = "Drupal\private_message\Entity\Builder\PrivateMessageThreadViewBuilder",
 *     "views_data" = "Drupal\views\EntityViewsData",
 *     "access" = "Drupal\private_message\Entity\Access\PrivateMessageThreadAccessControlHandler",

As you can see, there is access handler. Now you know how it works.

  protected function checkAccess(EntityInterface $entity, $operation, AccountInterface $account) {
    if ($account->hasPermission('use private messaging system')) {
      switch ($operation) {
        case 'view':
          if ($entity->isMember($account->id())) {
            $messages = $entity->filterUserDeletedMessages($account);
            if (count($messages)) {
              return AccessResult::allowed();
