Getting current node id in views

Question

I'm on drupal 8, and I'm trying to figure out how to get the current node id in an override of views-view-unformatted.html.twig.

I have a view filled with titles with added links and I want to add a class to the one the corresponds to the current node id.

Answer 1

You will get the node id in an override of views-view-unformatted.html.twig. Find below code

{% for row in rows %}
  {% set nid  = row.content['#row']._entity.nid.value %}
{% endfor %}

Answer 2

You'll find the node id from each row in _entity:

{{ row._entity.id }}

Answer 3

I did this in preprocess
In your .theme file :

function YOURTHEME_preprocess_views_view_unformatted(&$variables) {
  foreach($variables['rows'] as $key => $row){
    if(is_object($row['content']['#node'])){
      $variables['rows'][$key]['nid'] = $row['content']['#node']->id();
    }  
  }
}

And then in your template file

{{ row.nid }}

Will output the NID.

Answer 4

Added class "active", if node_id same.

In your .theme file :

function THEME_preprocess_views_view_unformatted__YOUR_NAME_VIEW__block_1(&$variables) {
  $node = \Drupal::request()->attributes->get('node');
  $node_id = $node->id();

  $view = $variables['view'];
  $rows = $variables['rows'];
  $id_view = $view->storage->id();

  if ($id_view == 'YOUR_NAME_VIEW' && $view->current_display == 'block_1') {
    $variables['#cache']['contexts'][] = 'url.path';

    foreach ($rows as $id => $row) {
      $view_node_id = $row['content']['#node']->id();

      if ($view_node_id == $node_id) {
        $variables['rows'][$id]['attributes']['class'][] = 'active';
      }

    }
  }

}

There is one condition!!! You need add any class in 'Row class' in your view.

FORMAT - Settings - Row class(The class to provide on each row.)
