Batch actions

Configure generator.yml

builders:
  list:
    batch_actions:
    delete: ~ # Pre coded action
    myCustomAction:
      label: Do custom
      confirm: Please confirm you want to do that

How to code your custom action

In your ListController add method :

<?php

protected function doBatchMyCustomAction(array $ids)
{
    if (2 == (1+1)) {
        $this->get('session')->setFlash('success', 'Hourri') );
        return;
    }
    
    $this->get('session')->setFlash('error', 'Cruel world!') );   
}

After the execution of your method doBatchMyCustomAction the controller will be redirected to the list.
