Django url tag multiple parameters

Question

I have two similar codes. The first one works as expected.

urlpatterns = patterns('',
                       (r'^(?P<n1>\d)/test/', test),
                       (r'', test2),
{% url testapp.views.test n1=5 %}

But adding the second parameter makes the result return empty string.

urlpatterns = patterns('',
                           (r'^(?P<n1>\d)/test(?P<n2>\d)/', test),
                           (r'', test2),)


{% url testapp.views.test n1=5, n2=2 %}

Views signature:

def test(request, n1, n2=1):

Answer 1

Try

{% url testapp.views.test n1=5,n2=2 %}

without the space between the arguments

Update: As of Django 1.9 (and maybe earlier) the correct way is to omit the comma and separate arguments using spaces:

{% url testapp.views.test n1=5 n2=2 %}

Answer 2

Here's an actual example of me using this technique. Maybe this will help:

{% if stories %}
  <h2>Stories by @{{author.username}}</h2>
  <ul>
    {% for story in stories %}
      <li><a href="{% url 'reader:story' author.username story.slug %}">{{story.title}}</a></li>
    {% endfor %}
  </ul>
{% else %}
  <p>@{{author.username}} hasn't published any stories yet.</p>
{% endif %}
