I am trying to create a simple way to execute certain actions on the database every time when I update a node.

I have been looking at Drupal’s Action module, however I can’t find any good manuals explaining how to use it. The ECA module works as a mechanism to launch my Action but I can’t execute my Action and I don’t know how to proceed.

I am currently creating my own module that will contain my actions. The following class is the class of my action.

<?php  namespace Drupalmy_custom_actionsPluginAction;  use DrupalCoreActionActionBase; use DrupalCoreSessionAccountInterface;  /**  * create custom action  *  * @Action(  *   id = "node_action",  *   label = @Translation("DataBase Action"),  *   type = "node"  * )  */ class DBAction extends ActionBase {      /**      * {@inheritdoc}      */     public function execute($node = NULL) {         if ($node) {             // TODO: procedure to execute in database             Drupal::messenger()->addStatus('The execution is OK, and we have the node');         }     }      /**      * {@inheritdoc}      */     public function access($object, AccountInterface $account = NULL, $return_as_object = FALSE) {         /** @var DrupalnodeNodeInterface $object */         // TODO: write here your permissions         $result = $object->access('update', $account, TRUE);         return $return_as_object ? $result : $result->isAllowed();     }  } 

The config/schema/module_test.schema.yml file like this :

action.configuration.module_test:   type: node_action   label: 'DataBase Action' 

config/install/system.action.node_action.yml

langcode: en status: true dependencies:   module:     - node id: node_action label: 'Export Content' type: node plugin: node_action configuration: {  } 

However, after update one node, two things happen:

• The variable $node of the execute method always comes in as null. Not entering to the if.
• The variable $object of the access method always comes as null. Throwing an error in $result = $object->access(‘update’, $account, TRUE);

I don’t know if the actions work only for Bulk Operations. But my goal is to only execute an action every time I update a node. Am I on the right track using Actions or not? Drupal documentation doesn’t seem very intuitive to me.

Thanks!
