Django - NameError: name 'app1' is not defined

I have just set up virtualenv and then created a new app, called "app1", under a new project, "devp1". I have edited the files as the following:

views.py in in "app1" dir

from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.

def home(request):
    return HttpResponse("wow my first page")

settings.py in "devp1" dir

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'app1',
]

url.py in "devp1" dir

urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'','app1.views.home'),
]

However, when I run the server, I receiving the following error, I have not found why it is not able to see "app1".

It looks like the quotation marks aren't in your views. The traceback shows 

url(r'', app1.views.home),

but your urls.py file shows 

url(r'','app1.views.home'),

Without those quotes it won't find the view in your application. I also don't think your regex will work the way you want it to. I would try this instead:

from app1 import views as app1_views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', app1_views.home, name='home'),
]
