Django NameSpace Error - django

Question

I designed this poll app and i'm trying convert a hard code url into an namespace url but had errors along the path.
This is my index.html and as you can see their an hard coded url that pointing to my URLconf.
{% if latest_poll_list %}
<ul>
{% for poll in latest_poll_list %}
<li>{{ poll.question }}</li>
{% endfor %}
</ul>
{% else %}
<p>No polls are available.</p>
{% endif %}
My myapp URLconf.
from django.conf.urls import patterns, include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls import patterns, include, url
urlpatterns = patterns('myapp.views',
url(r'^$', 'index', name="index"),
url(r'^(?P<poll_id>\d+)/$', 'detail',name="detail"),
url(r'^(?P<poll_id>\d+)/results/$', 'results', name="results"),
url(r'^(?P<poll_id>\d+)/vote/$', 'vote', name="vote"),
)
This is my main URLconf.
from django.conf.urls import patterns, include, url
from django.contrib import admin
from django.conf import settings
admin.autodiscover()
urlpatterns = patterns('',
url(r'^polls/', include('myapp.urls', namespace='myapp')),
,
)
My views are :
def detail(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
return render_to_response('myapp/detail.html', {'poll': p},
context_instance=RequestContext(request))
I tried to replace the hard coded error with {% url detail poll.id %} or {% url myapp:detail poll.id %}
but i received this error
NoReverseMatch at /polls/
Reverse for 'detail' with arguments '(5,)' and keyword arguments '{}' not found.
Request Method: GET
Request URL: http://127.0.0.1:8000/polls/
Django Version: 1.4.3
Exception Type: NoReverseMatch
Exception Value:

Error during template rendering
In template C:\djcode\mysite\myapp\templates\myapp\index.html, error at line 4
Reverse for 'detail' with arguments '(5,)' and keyword arguments '{}' not found.
1 {% if latest_poll_list %}
2 <ul>
3 {% for poll in latest_poll_list %}
4 <li>{{ poll.question }}</li>
5 {% endfor %}
6 </ul>
7 {% else %}
8 <p>No polls are available.</p>
9 {% endif %}
How can I convert this hardcoded URL into an namespace so It could point to myapp URLconf without any errors?

The way of doing it is different depending on use-case.
You can either do, which probably is your usecase.
{% url detail poll.id %}
Where the url-tag matches on the name detail and the following poll.id
The other way we would like to discuss here is if you're going to have multiple instances of the same app then you would have to use url namespaces. Discussed here
Main urls.py
url(r'^polls/', include('core.urls')),
Included urls.py
urlpatterns = patterns('',
url(r'^/(?P<polls_id>\d+)/$', 'core.views.polls_detail_view',name="poll_detail")
)
Template
To Poll Detail
`views.py``
def polls_detail_view(request, poll_detail):
print "Hello Poll detail: %s" % (poll_detail)
