I am embarrassed, but I need help on Tutorial

Using Django Getting Started
1

I have followed the tutorial “Writing your first Django app, part 1 | Django documentation | Django”.
But I am stuck and don’t see my error.

I get this error:

I have this directory layout:

-rw-rw-r-- 1 carsten carsten  170 Mär 29 11:25 urls.py

urls.py has this content:

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
path(‘polls/’, include(‘polls.urls’)),
path(‘admin/’, admin.site.urls),
]

And under the folder polls this structure:

with urls.py like this:

from django.urls import path

from . import views

urlpatterns = [
path(‘’, views.index, name=‘index’),
]

and views.py like this:

from django.http import HttpResponse


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

The "runserver" command shows this:

Can someone give me hint?

have you run python manage.py migrate?

Also make sure the polls app is added to your settings file

dunno but…

  1. add ‘polls’ to INSTALLED_APPS?
  2. try http://127.0.0.1:8000 and not http://localhost:8000/ ?

in all cases run migrate to get rid of that noise.

Hello chriswedgewood,

the tutorial says:

When I use the “migrate” the warnings dissapear, but the “polls” page is still not found.

Hello plopidou,

the tutorial doesn’t mention INSTALLED_APPS.
Where should I put that?

It doesn’t make a difference when I go to localhost or the 127.0.0.1.
The testpage shows, the admin page shows but the pollls not.

OMG! I got confused with the directory names.

I created the urls.py in the:

~/projects/django4/mysite

folder instead of:

~/projects/django4/mysite/mysite

That was my failure!
Thank you all for help.
