Django: href {% url %} issue

Question

Why does

<a href="{% url 'answers.views.display_answers' Question.id %}">View answers</a>

in my template translate to this interpretation by Django:

Request URL:    http://127.0.0.1:8000/questions/%7B%%20url%20'answers.views.display_answers'%20Question.id

which of course leads to an url mismatch error.

Seems like its reading in my '{' in ASCII form. Can anyone enlighten me as to why it is so?

EDIT:

This was how i rendered the template--

return render(request, 'display_questions.html', context) 

and the template contains the href. My display answer view redirects to another view as such:

def display_answers(request, q_id): 
        q = get_object_or_404(Question, id=q_id) 
        ans_list = Answer.objects.filter(question=q) 
        context = {'question': q, 'ans_list': ans_list} 
        return redirect('view_answers.html', context)

Error:

The current URL, questions/{% url 'answers.views.display_answers' Question.id, didn't match any of these.

Solution

This is correct. If not - your urls.py seems to be wrong. Please post it.

<a href="{% url answers.views.display_answers question.id %}">View answers</a>

Edit Here's a better version of your view.

from django.template import RequestContext
from django.core.urlresolvers import reverse
from django.shortcuts import render_to_response, redirect, get_object_or_404

def display_answers(request, q_id): 
    q = get_object_or_404(Question, id=q_id) 
    ans_list = Answer.objects.filter(question=q) 
    context = {'question': q, 'ans_list': ans_list} 
    return render_to_response('view_answers.html', context, RequestContext(request))

doesn't redirect need the reverse for named views? like return redirect(reverse('your_view_answers_view'))?

Didn't mean to downvote you, but now it's locked in. Can you edit your post insignificantly so it will allow me to change my vote?
