How do I update a field value in hook_entity_insert()?

Question

I want to update an field in hook_entity_insert(). The following code doesn't work.

$entity->field_range->value = 'test';
$entity->save();

I also tried loading from node object, but still it doesn't work.

$node = \Drupal::entityManager()->getStorage('node')->load($entity->id());
$node->set('field_range', 'test');
$node->save();

After inserting the node only I will get the text "test" dynamically and it won't work in hook_entity_presave().

Any help on how to update an field on hook_entity_insert will be nice. Thanks in advance.

Answer 1

From this solution we can able to do like below to update an field on hook_entity_insert

$entity->field_range->value = 'test';
drupal_register_shutdown_function('_cc_custom_post_insert',$entity);

function _cc_custom_post_insert($entity) {
    if($entity) {
        $entity->save();
    }
}

You can use hook_ENTITY_TYPE_presave as in hook_ENTITY_TYPE_update

When saving existing entities, the entity is assumed to be complete, partial updates of entities are not supported.

use Drupal\node\NodeInterface;

function mymodule_node_presave(NodeInterface $node) {
  switch ($node->getType()) {
    case "article":
      $node->set('field_range', 'test');
      break;
  }
}

Here no need to load node.
