Migrating to Twig Tweak 3.x

Dependencies

Twig Tweak 3.x requires Drupal 9, Twig 2 and PHP 7.3.

Rendering entities

Entity ID parameter in drupal_entity() and drupal_field() functions is now mandatory. Previously it was possible to load entities from current route by omitting entity ID parameter. However, that was making Twig templates coupled with routes and could cause caching issues.

Before:

{{ drupal_entity('node', null, 'teaser') }}

After:

{{ drupal_entity('node', node.id, 'teaser') }}

In case a template does not contain a variable with entity object you may prepare in a preprocess hook.

/**
 * Implements hook_preprocess_page().
 */
function preprocess_page(array &$variables): void {
  $variables['entity'] = \Drupal::routeMatch()->getParameter('entity_type');
}

Rendering blocks

drupal_block() now moves attributes provided by block plugin to the outer element. This may break some CSS rules.

Before:

<div>
  <div class="from-block-plugin">Block content</div>
</div>

After:

<div class="from-block-plugin">
  <div>Block content</div>
</div>
