Proble understanding DetailView url doesn't match the slug

[inoyon artlover KLANGRAUSCH]

Hi there, there is something I obviously don't understand. According to django reference,
the DetailView has to be provided a slug or pk. I do it in the url but django constantly doesn't
recognize the slug in the url.  'current url doesn't match etc.' what is wrong here? I do everything
like it is explaind and it doesn't work.. very frustrating sometimes...


My models.py:

class List01(models.Model):
    name = models.CharField(max_length=100, default='name')
    surename = models.CharField(max_length=100, default='surename')
    slug = models.SlugField()


views.py

class List(DetailView):
    template_name = 'index.html'
    model =List01

urls.py

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^(?P<slug>)$',List.as_view()),
)

That regex will never match anything. You need to give it some character classes to match:

     url(r'^(?P<slug>[\w-]+)$',List.as_view()),

which will match any alphanumeric characters or a hyphen, which are the usual components of a slug.

models.py

slug = models.SlugField(verbose_name='Slug', unique=True)

@models.permalink

def get_absolute_url(self):

    return ('myapp:List', (), {'slug': self.slug})

admin.py
from .models import List01


class ArticleAdmin(admin.ModelAdmin):
    prepopulated_fields = {"slug": ("name",)}

admin.site.register(List01, ArticleAdmin)

views.py

from django.shortcuts import render, get_object_or_404
from .models import List01

def List(request, slug):
   list = get_object_or_404(List01, slug=slug, released=True)
   context = {'list': list} #[1]
   return render(request, 'index.html', context)


urls.py

url(r'^(?P<slug>[\w-]+)/$', 'List', name='index'),

template
{% for lists in list %} # [1]
    <a href="{{lists.get_absolute_url}}"><h2>{{ lists.name }}</h2></a>
{% endfor %)

What is the specific error Django printed out ? We can narrow down the cause by checking the errors maybe.

Best Regards！
