I have a route set up with a slug accepting taxonomy terms (routing.yml):
example.column: path: '/column/{taxonomy_term}' I would like to add (secondary, although that's not important) local task tabs on a page, one for each possible term of the vocabulary used (links.task.yml):
example.column_list: deriver: 'Drupal\example\Plugin\Derivative\ColumnTasks' parent_id: example.parent The deriver is pretty straightforward and simple and mentioned in a few docs on drupal.org, the relevant part is:
foreach ($columns as $column) { $route_name = 'example.column'; $this->derivatives[$route_name] = [ 'title' => $column->getName(), 'route_name' => $route_name, 'route_parameters' => ['taxonomy_term' => $column->id()], 'parent_id' => 'example.parent', ] + $base_plugin_definition; } The problem is that this code, obviously, doesn't generate more than one tab because all go to the same $route_name. But I'm not allowed to use any other route name (suffixing it with the term, for instance) because it complains about a non-existent route then.
Do I have any other solution than to generate all the routes separately, using a _route_callback? This would somehow feel wrong, going against the reason for the existence of slugs in the first place.
