5. Adding administrative links

To provide a usable and integrated administration experience the different pages need to be connected and enriched with Drupal’s standard administrative links.

5.1. Add a menu link for the event listing

For the event listing to show up in the toolbar menu under Content, we need to provide a menu link for it.

• Add an event.links.menu.yml file in the event module directory with the following:

  entity.event.collection:
    title: 'Events'
    route_name: entity.event.collection
    parent: system.admin_content

• Rebuild caches

  Run drush cache:rebuild

• Verify that there is an Events link in the toolbar menu.

  Note that there is no Event local task on /admin/content.

5.2. Add a local task for the event listing

• Add an event.links.task.yml file in the event module directory with the following:

  entity.event.collection:
    title: 'Events'
    route_name: entity.event.collection
    base_route: system.admin_content

• Rebuild caches

  Run drush cache:rebuild

• Verify that the Events local task appears on /admin/content

5.3. Add local tasks for the edit and delete forms

• Add the following to event.links.task.yml:

  entity.event.canonical:
    title: 'View'
    route_name: entity.event.canonical
    base_route: entity.event.canonical
  entity.event.edit_form:
    title: 'Edit'
    route_name: entity.event.edit_form
    base_route: entity.event.canonical
  entity.event.delete_form:
    title: 'Delete'
    route_name: entity.event.delete_form
    base_route: entity.event.canonical

• Rebuild caches

  Run drush cache:rebuild

• Visit /events/2

  Verify that View, Edit and Delete local tasks are shown.
