Just until 5:27, everything was working properly, I ran django and is started showing me a no reverse match for course at /' . Here's my code:
layout.html:
{% load static from staticfiles %}
{% load course_extras %}
<!doctype html>
<html>
<head>
<title>{% block title %}{% endblock %}</title>
<link rel="stylesheet" href="{% static 'css/layout.css' %}">
{% block static %}{% endblock %}
</head>
<body>
<div class="site-container">
<div>{% nav_course_list %}</div>
<nav>
<a href="{% url 'views.hello_world' %}">Home</a>
<a href="{% url 'courses:list' %}">Courses</a>
</nav>
<p>Don't miss our newest course, {% newest_course %}</p>
{% block content %}{% endblock %}
</div>
</body>
</html
course_extras.py:
from django import template
from courses.models import Course
register = template.Library()
@register.simple_tag
def newest_course():
'''Get the recent course from the courses library. '''
return Course.objects.latest('created_at')
@register.inclusion_tag('courses/course_nav.html')
def nav_course_list():
''' Returns a list of courses to display as nav pane. '''
courses = Course.objects.all()
return {'courses': courses}
and course_nav.html:
{% for course in courses %}
<div><a href="{% url 'course:detail' pk=course.pk %}">{{ course.title }}</a></div>
{% endfor %}
Any sggestions ?

"""learning_site URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/1.8/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: url(r'^$', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: url(r'^$', Home.as_view(), name='home')
Including another URLconf
1. Add an import: from blog import urls as blog_urls
2. Add a URL to urlpatterns: url(r'^blog/', include(blog_urls))
"""
from django.conf.urls import include, url
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from . import views
urlpatterns = [
url(r'^courses/', include('courses.urls', namespace='courses')),
url(r'^admin/', include(admin.site.urls)),
url(r'^$', views.hello_world),
]
urlpatterns += staticfiles_urlpatterns()
Here's learning_site/courses/url.py:
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.course_list, name='list'),
url(r'(?P<course_pk>\d+)/(?P<step_pk>\d+)/$', views.step_detail,

url(r'(?P<pk>\d+)/$', views.course_detail, name='detail'),

Post back if this doesn't fix it.
