Drupal 8 views ui : filter on custom field -

i m pretty new d8 , m trying following thing :

i have content type : movie. in content type have custom field api_id wich integer.

when on movie page want display under content block movies same api_id.

i have managed create block same movies same author can't figure out how to filter on api_id (i have played contextual filters ...)

any ideas ? thx

ok , manage want hook_views_query_alter() :

function my_module_views_query_alter(\drupal\views\viewexecutable $view, \drupal\views\plugin\views\query\querypluginbase $query) {     if($view->id() == 'my_view' && $view->current_display == 'my_block'){         $movie= node::load($view->args[0]);         if(is_object($movie)) {             foreach ($query->where &$condition_group) {                 foreach ($condition_group['conditions'] &$condition) {                     if ($condition['field'] == 'node__field_id_movie.field_id_movie_value') {                         $condition = array(                             'field' => 'node__field_id_movie.field_id_movie_value',                             'value' => $movie->get('field_id_movie')->value,                             'operator' => '=',                         );                     }                 }             }         }     } } 

to have first create view simple filter on field want override filter.
