  • No, I did not make any relationship. Commented Nov 13, 2018 at 10:29

    I think should be a relationship between the two nodes, otherwise will not know the fields of which metals node should show on which prices.

  • Theoretically, if I establish a relationship between them, then it will be possible to display the field of one node in the TWIG(!!!) template of another? Commented Nov 13, 2018 at 10:37
  • Better configure in UI how to display the referenced node. For TWIG see drupal.stackexchange.com/questions/198694/…

After you made reference between prices and metals implement hook_preprocess_node like the following:

use Drupal\node\Entity\Node;
 * Implements hook_preprocess_node().
function MyTemplate_preprocess_node(&$variables) {
  if ($variables['node']->bundle() == 'prices') {
    $price_node = $variables['node'];
    //- Get reference target id
     * @TODO: change field_reference_metals by the referenced field.
    $metals_node_target_id = $price_node->field_reference_metals->getValue()[0]['target_id'];

    //- Load metals referred node
    $metals_node = Node::load($metals_node_target_id);

    //- Set field_gold from metals node
    $variables['field_gold'] = $metals_node->field_gold->value;
    //- Set field_silver from metals node
    $variables['field_silver'] = $metals_node->field_silver->value;

In node--prices.html.twig template add:

   {{ field_gold }}
   {{ field_silver }}
  1. Change MyTemplate by your custom theme/module name.
  2. Change field_reference_metals by the field from your prices content type referred to metals.
  3. clear cache.
  • Thank you for your time. I did everything as you indicated, but I get an error The website encountered an unexpected error. Please try again later. Error: Class 'Node' not found in unctema_preprocess_node() (line 59 of themes\unctema\unctema.theme). Commented Nov 15, 2018 at 9:29
  • $metal_prices_node = Node::load($metal_prices_node_target_id); Commented Nov 15, 2018 at 9:32

  • Now site works, but I see error under my node - User error: "value" is an invalid render array key in Drupal\Core\Render\Element::children() (line 97 of core\lib\Drupal\Core\Render\Element.php). and I do not see the value from metal fields... Commented Nov 15, 2018 at 9:36
  • Try with the edit use ->value instead of ->getValue() ?
