Field 'id' expected a number but got '{{\r\n˓→ }}'

I am trying to do the official Django Tutorial. I just copy/pasted the code from tutorial ( I hope I didnt miss smth ). The view code affecting the result :


def results(request, question_id):
    response = "You're looking at the results of question %s."
    question=get_object_or_404(Question, pk=1)
    # return HttpResponse(response % question_id)
    return render(request,'polls/results.html',context)

def vote(request, question_id):
             'error_message': "You didn't select a choice.",}
    except (KeyError, Choice.DoesNotExist):
        return render(request,'polls/detail.html',context) 

    # Always return an HttpResponseRedirect after successfully dealing
    # with POST data. This prevents data from being posted twice if a
    # user hits the Back button.
    return HttpResponseRedirect(reverse('polls:results', args=(,)))


<h1>{{ question.question_text }}</h1>
{% for choice in question.choice_set.all %}
<li>{{ choice.choice_text }} -- {{ choice.votes }} vote{{ choice.votes|pluralize }
{% endfor %}
<a href="{% url 'polls:detail' %}">Vote again?</a>

I got this error

ValueError at /polls/1/vote/

Field ‘id’ expected a number but got ‘{{\r\n˓→ }}’

Share your urls code as well, also is that your complete views code.

I found the error was -> sign in file which dropped there when I copy/pasted code from tutorial.
