I have an endpoint that returns an array of Order entities, but it's caching the results so when a new order is placed the cache has to be cleared.

The code within the endpoint is:

// Tried this also.
// $this->orderManager->resetCache()
$orders = $this->orderManager->loadByProperties([
  'uid' => $this->customer->id(),
$response = new ResourceResponse($orders);
// maybe this doesn't work because it's an \Drupal\Entity\commerce\Order[]

return new ResourceResponse($orders);

What am I missing?

  • Have you tried looping over the orders and adding the dependency for each individually? – Clive Sep 21 '17 at 19:19
  • Had not tried that, thanks. Combined with 4k4's answer I'm all set. – Chris Rockwell Sep 21 '17 at 21:04

See the comment from @Clive, you can only add single objects as dependency. But you need to add a list tag as well, because the entity query may change because of entities added or modified that are not in the cached list.

$list_tags = \Drupal::entityTypeManager()->getDefinition('entity_type')->getListCacheTags();
  • Once combined with the loop this works great - thanks (again)! – Chris Rockwell Sep 21 '17 at 21:06
