How do I get $node->body $node->teaser?

Question

I'm migrating a large custom module and theme from Drupal 6 and can't work out how to convert references to $node->body and $node->teaser since they are no longer fields in the node object, right?

Answer 1

Use this code in a preprocess hook:

$node = \Drupal::entityManager()->getStorage('node')->load($nid);
$view_builder = \Drupal::entityManager()->getViewBuilder('node');
$variables['node_full'] = $view_builder->view($node, 'full');
$variables['node_teaser'] = $view_builder->view($node, 'teaser');
$variables['body_full'] = $node->body->view('full');
$variables['body_teaser'] = $node->body->view('teaser');

And in twig

{{ node_full }}
{{ node_teaser }}
{{ body_full }}
{{ body_teaser }}

Use the rendered node and configure the view modes full, teaser or a custom view mode. The single rendered field does not work well with other code.

Answer 2

I've made some progress. It seems that

{{ node.body.value|raw }}  ** unsafe! **

works well but I guess it skipping input filters, and

{{ node.body.value }}

shows the markup. Not quite sure how to get the body with input filters but not escape the markup.

Safety notice:

Don't use the raw filter if you cannot guarantee that the value is safe from unwanted user input!

You can get the body in twig via:

{{ content }}

After adding this to your THEME.theme file:

function THEME_preprocess_node(&$variables) {
  $node = &$variables['node'];
  $node_array = $node->toArray();
  $variables['node_teaser'] = $node_array['body'][0]['summary'];
}

You can pull it up in templates/node.html.twig with:

{{ node_teaser }}
