Hi Ammar,

This requires an update to the article_detail method. Instead of using 'Article.objects.get' when looking up the articles, we'll use get_object_or_404, so that we can assure that the bad pks are, indeed, handled (a 404 error is a 'Not Found' or broken error, so we're saying 'get the object, or if you can't, consider it broken'):

def article_detail(request, pk):
    article = get_object_or_404(Article, pk=pk)
    return render(request, 'articles/article_detail.html', {'article': article})

Hope this helps!
