entity - 在某些情况下删除实体 Drupal 8

Question

任务是删除满足某些指定条件的实体。我该怎么做？

$current_user = \Drupal::currentUser()->id();
$storage = \Drupal::entityManager()->getStorage('context');

$query = $storage->getQuery()->condition('user_id', $current_user);

$query = $storage->getQuery()->delete();
$query->condition('user_id', $current_user);
$query->condition('key_text', $key);

$query->execute();

但是代码返回: fatal error :调用未定义的方法 Drupal\Core\Config\Entity\Query\Query::delete()

要查询实体，您可以使用 entityQuery，下面的示例使用它。

// Get all users with email containing "xyz"
$query = \Drupal::entityQuery('user')
  ->condition('mail', "XYZ", 'CONTAINS');
$uids = $query->execute();

// Load these entities ($uids) in our case using storage controller.
// We call loadMultiple method and give $uids array as argument.     
$itemsToDelete = \Drupal::entityTypeManager()->getStorage('user')
  ->loadMultiple($uids);

// Loop through our entities and deleting them by calling by delete method.
foreach ($itemsToDelete as $item) {
  $item->delete();
}
