I've created a custom module to show On This Days in a block but they are not changing each day until I flush the caches.

I call the entity:

public function build() {
    $query = \Drupal::entityQuery('node');
    $query->condition('status', 1);
    $query->condition('type', 'on_this_day');
    $query->condition('field_filter_date', '-' . date("m-d"), 'CONTAINS');
    $entity_ids = $query->execute();


and then return from the build function like this:

return array(
        '#markup' => $content,
        '#cache' => array(
            'max-age' => 0,

Any ideas? I'm thinking entity cache or something but I'm quite new to this and not too sure

  • Hi, I am using that but I suspect that it's the entities caching or something? Dec 1, 2020 at 12:46

The way to invalid the Cache in a Block is with

   * {@inheritdoc}
  public function getCacheMaxAge() {
    return 0;

This comes from BlockBase

  • Thanks, I do have this in the code but no luck I'm afraid. Dec 1, 2020 at 12:46
