How to rebuild local action - drupal

Question

I would like to add one action to a page (let's say the route entity.node.canonical) but this action would appear and disappear from the page time to time.
So what I'm trying to do is to create the action using a deriver (I put my condition to show the action in the method getDerivativeDefinitions) and then, on a kernel event, I refresh the local actions using \Drupal::service('plugin.manager.menu.local_action')->clearCachedDefinitions();
But it still doesn't work !
So is anybody capable of showing me a method to show and hide an action ?
Here is my derivative:
class ConditionalAction extends DeriverBase implements ContainerDeriverInterface {
/**
* {#inheritdoc}
*/
public function getDerivativeDefinitions($base_plugin_definition)
{
// If the seconds is more than 30, hide the action.
if (date('s') > 30) {
return $this->derivatives;
}
// Else, show the action.
$menu_entry = $base_plugin_definition;
$menu_entry['route_name'] = 'my.route.name';
$menu_entry['title'] = 'Test action';
$menu_entry['appears_on'][] = \Drupal::routeMatch()->getRouteName();
$menu_entry['route_parameters'] = ['time' => date('s')];
$this->derivatives['my.action.name'] = $menu_entry;
return $this->derivatives;
}
}
And here is the event subscriber:
class MyModuleKernelSubscriber implements EventSubscriberInterface {
/**
* {#inheritdoc}
*/
public static function getSubscribedEvents() {
return [
KernelEvents::REQUEST => 'onKernelRequest'
];
}
/**
* Event called when a request is sent.
*
* #param \Symfony\Component\HttpKernel\Event\GetResponseEvent $event
*/
public function onKernelRequest(GetResponseEvent $event) {
// Do not consider the ajax requests.
$request = $event->getRequest();
if ($request->isXmlHttpRequest() === TRUE) {
return;
}
// Flush local action cache.
\Drupal::service('plugin.manager.menu.local_action')->clearCachedDefinitions();
}
}
So, here, on each request, the local action should be cleared and the code should go through my derivative. But it's not working... Any thought ?
I really need it to be an action ! And I really need the URL argument to be dynamic as well (here, $menu_entry['route_parameters'] = ['time' => date('s')];).
Thank you

Answer 1

By looking inside the console command drupal cache:reset, I found that the lines
$bins = Cache::getBins();
$bins['render']->deleteAll();
$bins['discovery']->deleteAll();
reset the local actions on each requests.
So I have my answer now.
Hope this will help !
