Django: 'module' object has no attribute 'index'

Question

I've been trying to learn Django for the past few days, but recently I've stumbled upon a problem I can't seem to fix. After finishing Django's own tutorial on writing your first app I decided to go through it again. Only now I would replace everything to fit the requirements of the original app I was building.

So, everything went well until I got to part 3. When I try to load http://localhost:8000/lru/ I get the following error message:

AttributeError at /lru/
'module' object has no attribute 'index'

Traceback:

    url(r'^$', views.index, name='index')
AttributeError: 'module' object has no attribute 'index'

My code:

views.py

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, world. You're at the poll index.")

lru/urls.py

from django.conf.urls import patterns, url

from lru import views

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

mysite/urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^lru/', include('lru.urls', namespace="lru")),
)

My folder structure looks like this:

mysite/
    lru
    templates
    polls
    manage.py
    mysite

lru/
    templates
    urls.py
    admin.py
    __init__.py
    models.py
    tests.py
    views.py

It's strange because I've done everything exactly as I did in the "polls" example turtorial. Just replacing the names. When I comment out url(r'^lru/', include('lru.urls', namespace="lru")), in mysite/urls.py, then http://localhost:8000/polls/ works fine, but I just can't seem to get /lru to work.

This is really killing me so any form of help would be appreciative!

Edit: Added full traceback

Answer 1

Import the urls.py module into your view. like this;

from django.http import HttpResponse
from . import urls

def index(request):
    return HttpResponse("Hello, world. You're at the poll index.")

Answer 2

Either do this :

from lru.views import *

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

or

from lru import views

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

I hope this helps.

Answer 3

The second argument of url() should be string, anway I would change the lru/urls.py to:

from django.conf.urls import patterns, url

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

Hope it helps!
