I have three custom entities, all generated with Drupal Console. I only added some basicFieldDefinitions to them before testing some CRUD operations on them.

I have these entities:

  • ConfigEntity (config entity - lowest level)
  • ChildEntity (content entity - has an entity_reference field to ConfigEntity)
  • ParentEntity (content entity - has an entity_reference field to ChildEntity)

When I display the name of the ConfigEntity through the entire chain, it displays properly

// "Original Value"
$parentEntity->get('child_entity')->entity->get('config_entity')->entity->label()

When I update the name, it still displays the original value through the chain, although printing it from the entity itself, it is the new value.

// "Original Value"
$parentEntity->get('child_entity')->entity->get('config_entity')->entity->label();

$configEntity = ConfigEntity::load(1);
$configEntity->set('label', "New Value")->save();

$configEntity = ConfigEntity::load(1);

// "New Value"
$configEntity->label();

$parentEntity = ParentEntity::load(1);

// "Original Value" instead of "New Value"
$parentEntity->get('child_entity')->entity->get('config_entity')->entity->label();

Any idea if there's a cache tag mechanism I have to implement manually, or something I have to invalidate myself in code?

You can clear the static entity cache with EntityStorageBase::resetCache:

\Drupal::entityTypeManager()->getStorage('parent_entity')->resetCache([$parentEntity->id()]);
  • Thanks! Is it best to add this to the save() method of the child? – KevinVRansbeeck Apr 11 at 6:30
  • Most times this is not necessary, because what you are doing is testing and rarely happens in production where you usually save entities in post requests. – 4k4 Apr 11 at 6:46
  • I see, thanks @4k4! – KevinVRansbeeck Apr 11 at 9:50
