Django namespaced URLs and parameters

I'm encountering an odd problem with namespaced url in Django, and I cannot find what I am doing wrong while it is working on simpler examples and using the

Basically, my project is made of two apps, user and model. In my general urls.py, I defined :

url(r'^model/', include('model.urls', namespace="model")),
url(r'^user/', include('user.urls', namespace="user")),

In the user.urls.py file, I defined the following url:

url(r'^duo/(?P<pseudo>[a-z]+)/$',views.duo, name='duo'),

The duo view is rather simple :

def duo(request,pseudo):
     print pseudo
     return render(request,"user/duo.html",locals())

Therefore, when I use in my templates:

{% url 'user:duo' lena %}

I expect the url to be resolved as /user/duo/lena. Instead, I got the following NoReverseMatch:

 Reverse for 'duo' with arguments '('',)' and keyword arguments '{}' not found. 1 pattern(s) tried: [u'user/duo/(?P<pseudo>[a-z]+)/$']

I take any guess to fix my mistake !

Edited according to the dicussion: You need to quote your paramater. Also keyword parameters might make things clearer:

{% url 'user:duo' pseudo='lena' %}

If you don't quote the value, Django assumes this is a context variable and as lena is not a context variable in your case this evaluates to None. The error actually tells you, you didn't provide args or kwargs for the reverse lookup.
