Adding blacklist actions to related entites für FoC/CrudView

gistfile1.txt

In your controller action set it up like that:
  $action->config('scaffold.relations_actions_blacklist', [
    'Registrations' => ['edit', 'delete'], // only allow view action
    'Rewards' => ['delete'], // don't allow delete
  ]);

Change/add this in the appropriate place in the Template/Element/view/relations/has_many.ctp which you have copied from the CrudView plugin to your own src/ dir:

  foreach (${$viewVar}->{$details['entities']} as ${$otherSingularVar}) :
  .
  .
  .
      <td class="actions">
        <?php $actions_blacklist = \Cake\Utility\Hash::get($actionConfig, 'scaffold.relations_actions_blacklist.' . $alias); ?>
        <?= $blacklist && in_array('view', $actions_blacklist) ? '' : $this->Html->link(__d('crud', 'View'), array('plugin' => $details['plugin'], 'controller' => $details['controller'], 'action' => 'view', ${$otherSingularVar}[$details['primaryKey']])); ?>
        <?= $blacklist && in_array('edit', $actions_blacklist) ? '' : $this->Html->link(__d('crud', 'Edit'), array('plugin' => $details['plugin'], 'controller' => $details['controller'], 'action' => 'edit', ${$otherSingularVar}[$details['primaryKey']])); ?>
        <?= $blacklist && in_array('delete', $actions_blacklist) ? '' : $this->Html->link(__d('crud', 'Delete'), array('plugin' => $details['plugin'], 'controller' => $details['controller'], 'action' => 'delete', ${$otherSingularVar}[$details['primaryKey']])); ?>
      </td>
  .
  .
  .
  endforeach;
