Django how to use generic view with UUID instead of PK - django

Question

I'm trying to access a url that's like
127.0.0.1:8000/posti/qNwEXBxXQdGI4KlQfoHWOA
However I can't resolve that smalluuid.
This is the error:
NoReverseMatch at /posti/ Reverse for 'detail' with arguments
'(SmallUUID('qNwEXBxXQdGI4KlQfoHWOA'),)' not found. 1 pattern(s)
tried: ['posti/(?P[0-9a-fA-F-]+)/$']
Django has issues trying to resolve it in another view that has a string like this:
from . import views
from django.conf.urls import url
app_name = 'posti'
urlpatterns = [
url(r'^$', views.IndexView.as_view(), name='index'),
url(r'^(?P<slug>[0-9a-fA-F-]+)/$', views.DetailView.as_view(), name='detail'),
My DetailView is this one:
class DetailView(generic.DetailView):
model = Post
template_name = 'posti/detail.html'
slug_field = 'uuid'
def get_queryset(self):
"""
Excludes any questions that aren't published yet.
"""
return Post.objects.all()
I tried rewriting get_object but it didn't do anything. I don't understand if the regex is wrong or if my view has something wrong.
EDIT:
My template on index raised the error above and it had the following code:
{% if posti_list != null %}
<ul>
{% for post in posti_list %}
<li>{{ post.title }}</li>
{% endfor %}
</ul>
{% else %}
<p>No posts are available.</p>
{% endif %}
I added slug_url_kwarg = 'uuid' to the DetailView class and now it works BUT now I have a
AttributeError at /posti/qNwEXBxXQdGI4KlQfoHWOA/ Generic detail view
DetailView must be called with either an object pk or a slug.
When I try to access the specific post.

I added slug_url_kwarg = 'uuid' to the DetailView class and now it works BUT now I have a

slug_url_kwarg must match your url regex group name (slug in your case, which is default value for slug_url_kwarg), so you shouldn't have changed it
For details look at the piece of Django source code here - https://github.com/django/django/blob/master/django/views/generic/detail.py#L8
