How to render field of one type of node to another type node

Question

I have two types of nodes: metals and prices.

Metals has two fields:

field_gold

and

field_silver

How to render this fields on node--prices.html.twig (not node--metals.html.twig)

Please, help me!

Answer 1

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.
