ノードのコンテンツタイプの変更

Question

Drupal 7では、 Node convert を使用してノードのコンテンツタイプを簡単に切り替えることができます。ただし、Node Convert、ただし 移植されていません からDrupal 8、また、移植に対する熱意があまりないようです。

同じフィールドを持つ2つのコンテンツタイプがある場合、ノードをコンテンツタイプから別のコンテンツタイプに変換するにはどうすればよいですかDrupal 8？Drupal 8、これは次のDrupal 7Node convertモジュールで使用されるコード）と同等ですか？ （ node_convert.util.inc のnode_convert_node_convert()を参照してください。）

_  // $nid, $destination_node_type, $source_fields, $destination_fields,
  // $no_fields_flag, and $hook_options are the parameters passed to the function.

  $node = node_load($nid);
  if ($node == FALSE) {
    return FALSE;
  }

  // Change the node type in the DB
  db_update('node')->fields(array('type' => $destination_node_type))->condition('nid', $nid)->execute();

  // If there are fields that can be converted
  if ($no_fields_flag == FALSE) {

    // Conversion process for each field
    $re_save_body_field = FALSE;

    // Use node revisions to extract all field revision in node_convert_field_convert
    $node_revisions = node_revision_list($node);

    foreach ($source_fields as $key => $field) {
      $replaced_body = node_convert_field_convert($node, $field, $destination_fields[$key], $destination_node_type, $node_revisions);
      if ($replaced_body == REPLACE_BODY) {
        $re_save_body_field = TRUE;
      }
    }
    // If something was appended to the body, or replaced the body, we update body field.
    if ($re_save_body_field == TRUE) {
      $field_body = field_info_fields();
      $field_body = $field_body['body'];
      $field_ids = array($field_body['id'] => $field_body['id']);
      module_invoke($field_body['storage']['module'], 'field_storage_write', 'node', $node, FIELD_STORAGE_UPDATE, $field_ids);
    }
  }

  // Omissis.

  // Clear the node cache, so we have the latest information when saving the
  // node.
  $controller = entity_get_controller('node');
  /* @var $controller DrupalEntityControllerInterface */
  $controller->resetCache(array($node->nid));
  cache_clear_all('field:node:' . $node->nid, 'cache_field');

node_convert_field_convert()には、次のコードが含まれています。

_  // &$node, $source_field, $destination_field, $destination_node_type,
  // and $node_revisions are the parameters passed to node_convert_field_convert().

  $field_info_source = $field_info_source[$source_field];

    // Delete node info in the separate field table
    node_convert_invoke_field_storage_delete($field_info_source, $db_info_source, $node);
    return NULL;
  }

  $field_info_destination = array();

  // We save each field value from the DB for transfer. (this only applies to the current revision of the field)

Answer 1

しばらく時間が経過し、d8の convert_bundles モジュールが追加されました。

これはアルファ版ですが、開発サイトでエンティティを変換するために使用することができました。

Answer 2

Joachim Noreikoが ノードのタイプの変更 に関するブログ投稿を投稿しました。次のテーブルを更新する必要があります。

• エンティティベーステーブル
• エンティティデータテーブル
• エンティティリビジョンデータテーブル
• 各フィールドデータテーブル
• 各フィールドデータリビジョンテーブル

投稿には完全な手順とコードスニペットが付属しています。

Answer 3

以下は、記事ノードをブログタイプに変換するためのソリューションです。別の回答で提案されているConvert Bundlesを試しましたが、変換するノードをフィルターできませんでした。これにより、分類用語の値などの条件をクエリに追加できます。

$query = \Drupal::entityQuery('node')
  ->condition('type', 'article')
$results = $query->execute();

foreach ($results as $nid) {
  $node = \Drupal\node\Entity\Node::load($nid);
  $node->set('type', 'blog');
  $node->save();
}
