Python Django - the included URLconf '<module '{spp}.urls' from {path} does not appear to have any patterns in it

Question

I am working through chapter 18 in Python Crash Course by Eric Matthes, which is a tutorial on how to create web apps with Django. Currently I'm mapping a URL, writing a view, writing a template, and then trying to deploy the app on my system so I can see the homepage I created.

Here are the relevant files/code:

urls.py-learning_log

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

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('learning_logs.urls'))
]

urls.py-learning_logs

"""Defines URL patterns for learning_logs."""
from django.urls import path
from . import views

app_name = 'learning_logs'
url_patterns = [
    # Home page
    path('', views.index, name='index'),
]

views.py

from django.shortcuts import render

def index(request):
    """The home page for Learning Log."""
    return render(request, 'learning_logs/index.html')

index.html

<p>Learning Log</p>

<p>Learning Log helps you to keep track of your learning, for any topic you're learning about.</p>

When I try to create the server using the runserver command from within the virtual environment for the project using Powershell for Windows, here's the error I get:

(ll_env) PS C:\Users\Samie\Desktop\python_work\learning_log> python manage.py runserver

During handling of the above exception, another exception occurred:

circular import.

That's quite a lot for me to digest as a super green Python/Django user. Can anybody see where I am going wrong here? I know that the version of Django I have installed for this project is newer than when the book was published (2019), can that be the issue? Thank you for any help provided!

Answer 1

The problem is in your urls.py-learning_logs. You misspelled urlpatterns as the name of the list. The spelling should be exactly urlpatterns. Hence the error ... does not appear to have any patterns in it...

Just change url_patterns to urlpatterns

urls.py-learning_logs

"""Defines URL patterns for learning_logs."""
from django.urls import path
from . import views

urlpatterns = [
    # Home page
    path('', views.index, name='index'),
]
