You should be using render instead of render_to_response. You should also include article in the template context if you use it. Deindent the template and contect lines, so that the view works for invalid post requests.

def addcomment(request, a_id):
    article = get_object_or_404(Articles,id=a_id)

    if request.method == 'POST':
        ...
    else:
        form = CommentForm()
    template = 'addcomment.html'
    context = {'form': form, 'article': article}

    return render(request, template, context)
