Django NoReverseMatch Error - django

Question

I'm trying to develop a blog script with Django. But when I want to show post links, I get NoReverseMatch error.
My views.py
# -*- coding: utf-8 -*-
# Create your views here.
from .models import Yazi, Yorum, Kategori
from django.http import HttpResponse, Http404
from django.shortcuts import render_to_response
from django.template import RequestContext, loader
from django.contrib.sites.models import Site
def Home(request):
try:
posts = Yazi.objects.filter(yayinlanmis=True).order_by('-yayinlanma_tarihi')
except Yazi.DoesNotExist:
raise Http404
site = Site.objects.get_current()
c = RequestContext(request,{
'posts':posts,
'site':site
})
return render_to_response('Penguencik_Yazilar/yazi_list.html', c)
def Detail(request, slug):
post = Yazi.objects.get(slug=slug)
site = Site.objects.get_current()
c= RequestContext(request,{
'posts':post,
'site':site
})
return render_to_response('Penguencik_Yazilar/yazi_detail.html',c)
Urls.py in application folder.
from django.conf.urls import patterns, url
import views
urlpatterns = patterns('',
url(r'^$', views.Home,name='index'),
url(r'^/makale/(?P<slug>[0-9A-Za-z._%+-]+)$', views.Detail,name='detail'),
)
Urls.py in project folder
from django.conf.urls import patterns, include, url
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^$', include('Penguencik_Yazilar.urls',namespace='blog')),
url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
url(r'^admin/', include(admin.site.urls)),
)
And template code. What am I doing wrong?
{% load url from future %}
...
Read

Answer 1

Try to change this:
Read
to:
Read
Cause your view expect slug keyword here (?P<slug>[0-9A-Za-z._%+-]+).
