Делаю django ЧПУ с помощью slug но выдает ошибку

Я хочу чтобы url выводилося названия статьи типо programs/kak-vzlomat-jopu или как то так. И еще настораживает то что как рагумент берет slug : 13 а это вообще из другой колонки в database

в шаблоне передаю slug в url вот так

  <a href="{% url 'article_detail'  slug=top.slugProg %}">
