Modification du type de contenu d'un nœud

Dans Drupal 7, je peux facilement changer le type de contenu d'un nœud en utilisant la conversion de nœud . Node Convert, cependant, n'a pas été porté sur Drupal 8, et il ne semble pas y avoir beaucoup d'enthousiasme pour le port.

Si j'ai deux types de contenu avec des champs identiques, comment puis-je convertir un nœud d'un type de contenu en un autre, dans Drupal 8? Quel code dois-je utiliser pour Drupal 8, qui est équivalent au code Drupal 7 suivant utilisé par le module de conversion Node ? (Voir node_convert_node_convert()dans node_convert.util.inc .)

  // $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() contient le code suivant.

  // &$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_fields(); // Get source field information
  $field_info_source = $field_info_source[$source_field];
  $db_info_source = $field_info_source['storage']; // Get DB specific source field information

  if ($destination_field == 'discard') {
    // Delete node info in the separate field table
    node_convert_invoke_field_storage_delete($field_info_source, $db_info_source, $node);
    return NULL;
  }

  $field_info_destination = array();
  $db_info_destination = array();
  if (!in_array($destination_field, array('discard', APPEND_TO_BODY, REPLACE_BODY))) {
    $field_info_destination = field_info_fields($destination_field); // Get destination field information
    $field_info_destination = $field_info_destination[$destination_field]; // Get destination field information
    $db_info_destination = $field_info_destination['storage']; // Get DB specific destination field information
  }

  // We save each field value from the DB for transfer. (this only applies to the current revision of the field)
  $source_values = field_get_items('node', $node, $source_field);

  if (count($node_revisions) > 1 && !in_array($destination_field, array(APPEND_TO_BODY, REPLACE_BODY))) {
    // Get all field revisions for current node
    $field_revision_values = array();
    $field_revision_source_table = current(array_keys($db_info_source['details']['sql']['FIELD_LOAD_REVISION']));

    $source_columns = array('entity_type', 'entity_id', 'revision_id', 'bundle', 'delta', 'language');
    foreach ($field_info_source['columns'] as $column => $attributes) {
      $source_columns[] = _field_sql_storage_columnname($source_field, $column);
    }

    $revision_query = db_select($field_revision_source_table, 'r', array('fetch' => PDO::FETCH_ASSOC))
      ->condition('entity_type', 'node')
      ->condition('bundle', $node->type)
      ->condition('entity_id', $node->nid)
      ->condition('revision_id', $node->vid, '<>')
      ->fields('r', $source_columns)->execute();

    // Change the bundle to the destination type of the node
    foreach ($revision_query as $row) {
      $row['bundle'] = $destination_node_type;
      $field_revision_values[] = $row;
    }

    // Remove all field revisions for current field in DB
    node_convert_invoke_field_storage_delete($field_info_source, $db_info_source, $node);

    node_convert_invoke_field_storage_delete($field_info_source, $db_info_source, $node);

  // The source field value should be appended to the body or replaced.
  if ($destination_field == APPEND_TO_BODY || $destination_field == REPLACE_BODY) {
    static $node_body = '';
    //static $node_teaser = '';

    // We try to get the node body from a static variable, which means we did some body manipulations, otherwise load it.
    if (empty($node_body)) {
      $node_body_field = field_get_items('node', $node, 'body');
      $node_body = $node_body_field[0]['value'];
      //$node_teaser = $node_body_field[0]['summary'];
    }

    if (is_array($source_values)) {
      // Get the field value.
      $field_value = node_convert_format_field_value($node, $field_info_source, TRUE);

Un certain temps s'est écoulé, et la bonne nouvelle est qu'il existe désormais le module convert_bundles pour d8.

C'est alpha, mais j'ai pu l'utiliser pour convertir des entités sur un site de développement.

Joachim Noreiko vient de publier un article de blog sur la modification du type d'un nœud . Vous devrez mettre à jour les tableaux suivants:

• la table de base d'entité
• la table de données d'entité
• la table de données de révision d'entité
• chaque table de données de champ
• chaque table de révision des données de champ

La publication est livrée avec des instructions complètes et des extraits de code, suivez-les étape par étape.

Voici une solution pour convertir les nœuds d'articles en un type de blog. J'ai essayé Convert Bundles suggéré dans une autre réponse, mais je n'ai pas pu filtrer les nœuds à convertir. Avec cela, vous pouvez ajouter des conditions supplémentaires à la requête, comme une valeur de terme de taxonomie.

$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();
}
