Custom taxonomy & post slug permalink

Question

I have a custom taxonomy and a custom post type. I'm aiming for the following permalink structure:

{custom taxonomy}/{custom taxonomy term}/{custom post slug}

Or, at the very least,

{custom taxonomy term}/{custom post slug}

I currently have

{%category%}/{%postname%}, but no dice.

For example, assume I have:

• a taxonomy states, and a taxonomy term newyork
• a custom post type jobs with a post that has the slug wordpress-developer

I am looking to achieve:

• states/newyork: an archive of all the jobs in newyork, this works.
• states/newyork/wordpress-developer: the custom post's page using the taxonomy & term as the base in the permalink.

The goal is to navigate from states/newyork (list of "jobs" and flow into the individual post w/o deviating from the permalink structure thus far, so states/newyork/wordpress-developer

Problems encountered:

• states/newyork/wordpress yields a 404
• newyork/wordpress-developer redirects to jobs/wordpress-developer

Desired outcome:

• states/newyork/wordpress-developer landing on the custom post type page

PS - not building another job board, just using this as an example :)

current taxonomy & post type register hook:

function register() {
  register_taxonomy('state', 'district', array(
    'labels' => array(
      'name' => 'States',
      'singular_name' => 'State',
      'search_items' => 'Search States',
      'all_items' => 'All States',
      'parent_item' => 'Parent State',
      'parent_item_colon' => 'Parent State:',
      'edit_item' => 'Edit State',
      'update_item' => 'Update State',
      'add_new_item' => 'Add New State',
      'new_item_name' => 'New State',
      'menu_name' => 'States'
    ),
    'public' => true,
    'show_admin_column' => true,
    'hierarchical' => true,
    'query_var' => true,
    'rewrite' => array(
      'slug' => 'states',
      'with_front' => false
    )
  ));

  register_post_type('district',
    array(
      'labels' => array(
        'name' => 'Districts',
        'singular_name' => 'Districts'
      ),
      'hierarchical' => true,
      'supports' => array('title', 'page-attributes'),
      'public' => true,
      'has_archive' => 'states',
      'rewrite' => array(
        'with_front' => false,
        'slug' => 'states/%show_category%'
      )
    )
  );
}

I was able to solve this by defining a rewrite rule:

function rewrite_rules($rules) {
  $newRules = array();
  $newRules['states/(.+)/(.+?)$'] = 'index.php?district=$matches[2]';
  return array_merge($newRules, $rules);
}
add_filter('rewrite_rules_array', __NAMESPACE__ . '\\rewrite_rules');
