NoReverseMatch help (step 2, course_list)

Hi! So I've gotten through changing the urls for the homepage in Dango 1.10.0 just fine, but now am stuck and not quite sure what to do to get the course_list url to function properly. I know other people have had this problem, but I haven't seen any questions/answers for changing the course_list URL.

Here's what my URL patterns looks like: 

urlpatterns = [
    url(r'^courses/', include('courses.urls', namespace='courses')),
    url(r'^admin/', admin.site.urls),
    url(r'^$', views.homepage, name='hello_world'),
]

And when the link in the layout.html I'm trying is :

<a href="{% url 'courses:course_list' %}">Courses</a>

But this doesn't work. I've looked up how URLs work in Django but I'm not sure how to access the 'courses/views.py' instead of the 'root/views.py', or even if that's what I need to be doing. Do I need to be putting the path to the courses.view somewhere? If so, where? Sorry, I'm confused from looking up things for so long and could do with some help.

Hi I am not entrily sure of your question so apologies if I get this completley wrong.

If you are asking to show the list of courses in your template ?

if yes have you a urls.py with the following pattern under courses?

urlpatterns = [
    url(r'^$', views.course_list),
]

Also in your views.py have you created the course-list view?

def course_list(request):
    courses = Course.objects.all()
    return render(request, 'courses/course_list.html', {'courses': courses})

As can be seen above the course_list renders the course_list.html template, however, you can change this to whta ever you want. To access the the list in the course_list function it renders the object courses to the template. So then you can access that object in the template :

{% for course in courses %}
   {{ course.title }}
   {{ course.description }} 
{% endfor %}

Hope this makes some sense and I answered some of your question :)
