Modifica del tipo di contenuto di un nodo

In Drupal 7, posso facilmente cambiare il tipo di contenuto di un nodo usando Node convert . Node Convert, tuttavia, non è stato portato su Drupal 8, né sembra esserci molto entusiasmo per il porto.

Se ho due tipi di contenuto con campi identici, come posso convertire un nodo da un tipo di contenuto a un altro, in Drupal 8? Qual è il codice che dovrei usare per Drupal 8, che equivale al seguente codice Drupal 7 usato dal modulo di conversione Node ? (Vedi node_convert_node_convert()in 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() contiene il seguente codice.

  // &$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']));

      $source_columns[] = _field_sql_storage_columnname($source_field, $column);
    }

      ->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) {

      $field_revision_values[] = $row;
    }

      $node_body = $node_body_field[0]['value'];

    }

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

È passato del tempo e la buona notizia è che ora c'è il modulo convert_bundles per d8.

È alfa, ma sono stato in grado di usarlo per convertire entità su un sito di sviluppo.

Joachim Noreiko ha appena pubblicato un post sul blog sulla modifica del tipo di nodo . Dovrai aggiornare le seguenti tabelle:

• la tabella di base dell'entità
• la tabella dei dati dell'entità
• la tabella dei dati di revisione dell'entità
• ogni tabella di dati di campo
• ogni tabella di revisione dei dati di campo

Il post viene fornito con istruzioni complete e frammenti di codice, basta seguirli passo dopo passo.

Ecco una soluzione per convertire i nodi di articoli in un tipo di blog. Ho provato Convert Bundles suggerito in un'altra risposta, ma non sono stato in grado di filtrare quali nodi convertire. Con questo, è possibile aggiungere condizioni aggiuntive alla query, come un valore del termine tassonomia.

$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();
}
