function translation_views_query_views_alter in Translation Views 8

Implements hook_query_TAG_alter().

Add support to use views query substitutions in expressions from hook_views_query_substitutions(). Expressions can be used in views fields (i.e addField()), and views orderBy formula (i.e addOrderBy()).

@todo Remove this workaround when will be solved in drupal core.
