I finally did it by adding the code to handle the comment in the same view that renders the articles this is my code 

def _article(request, article_id):
try:
    article = Article.objects.get(pk=article_id)
    related_articles = Article.objects.filter(tags=article.tags).exclude(pk=article.pk)[:4]
    context['article'] = article
    context['related_articles'] = related_articles
    context['form'] = CommentForm()
    if request.method == 'POST':
        form = CommentForm(request.POST)
        if form.is_valid():
            comment = form.cleaned_data['comment']
            article.comments_set.create(comment=comment)
    return render(request,'blog/article.html', context)
except Exception as e:
    #write error to file
    return render(request,'blog/404.html')

If you don't want the page to redirect to another page or update the page, you should use AJAX (https://www.w3schools.com/jquery/jquery_ajax_get_post.asp) in this case. Your form will hit the url in the action by changing your page to that url so you have to handle the redirecting and rendering in your commenting view to come back to same page if you don't wanna do this dynamically.
