python - Django : Page Not found

I have looked around and can't really find a solution to my problem. Here is the error django throws. This error is being thrown when on my homepage I have a fiew links that upon clicking should direct you to a details view of said link.

Using the URLconf defined in untitled.urls, Django tried these URL patterns, in this order:

    ^$
    ^index/ ^$ [name='index']
    ^index/ ^(?P<distro_id>[0-9]+)/$ [name='distro_id'] 
    ^admin/

The current URL, index//, didn't match any of these.

To my knowledge I don't understand why this error is being thrown.

Here is my urls.py

from django.conf.urls import include, url
from django.contrib import admin
import index.views
urlpatterns = [
    url(r'^$', index.views.index),
    url(r'^index/', include('index.urls', namespace='index')),
    url(r'^admin/', admin.site.urls),
]

My index/urls.py

from django.conf.urls import url
from . import views


urlpatterns = [
    # /index/
    url(r'^$', views.index, name='index'),

    #/distro/123/
    url(r'^(?P<distro_id>[0-9]+)/$', views.detail, name='distro_id'),

]

My views.py

from django.shortcuts import get_object_or_404, render
from django.template import loader, RequestContext
from django.http import Http404
from .models import Distros


def index(request):
    all_distros = Distros.objects.all()
    context = {'all_distros': all_distros, }
    return render(request, 'index/index.html', context)


def detail(request, distro_id,):
    distro_id = get_object_or_404 (Distros, pk=distro_id)
    return render(request, 'index/detail.html', {'distro_id': distro_id})

template code:

    {% extends 'index/base.html' %}

{% block body %}
<ul>
    {% for distro in all_distros %}
        <li><a href="/index/{{ distro_id }}/">{{ index.distro_id }}</a></li>
    {% endfor %}
</ul>
{% endblock %}

I believe those are all the relevent files. I believe everything is setup correctly so I am not sure why the error is being thrown. I'm sure im missing something simple that i'm just overlooking.

Please don't use hardcoded URLs as they are error prone as in your situation. Instead of:

<a href="/index/{{ index.distro.id }}/">

use the url template tag with your namespace (index) and view name (distro_id):

<a href="{% url 'index:distro_id' index.id %}">

Note that you also have an error with index.distro.id as index is actually a Distros object. It has an id field, but not distro.id.
