Having trouble running my Django app

Question

I am learning to build a Django app named rango from the site http://www.tangowithdjango.com/ , but things are bit different as I am using Django 1.9 which is not same as in the tutorial, so I am facing difficulty in running the app. Whenever I run the server, it gives error as

 NameError: name 'rango' is not defined

I have included rango in the INSTALLED_APPS list. Here is my master urls.py file's code:

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

And here is my local urls.py file (rango's urls.py) that is kept within the /rango folder:

from django.conf.urls import patterns, url
from rango import views

urlpatterns=patterns('',
    url(r'^$',views.index,name='index'),)

So why is my rango app not being located?

Answer 1

This is happening because the rango.urls has to be in quotes. So your master urls.py should look like this -

from django.conf.urls import include,url
from django.contrib import admin


urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^rango/', include('rango.urls')),
]
