No module named 'urls' in Django

Question

I’m studying about URL division in Django and I can’t direct my main url file to high school.

Tracking:

Traceback (most recent call last):

Main file of Urls:

from django.conf.urls import url, include
from django.contrib import admin
from simplemooc.core import views
from simplemooc.core import urls

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

Secondary URL file:

from django.conf.urls import url
from simplemooc.core import views   

urlpatterns = [
    url(r'^$', views.home, name='home'),
    url(r'^contato/$', views.contact, name='contact'),
]

Error:

ModuleNotFoundError: No module named 'urls'

Could help?

Thank you.

By the message, your module urls can not be imported for some reason, let’s create a minimalist project to see how it works:

Create a Django project in a temporary directory:

$ django-admin startproject hello  

Go to the project directory and create an app called core:

$ cd hello
$ django-admin startproject hello

Edit the file hello/settings.py and, in the section INSTALLED_APPS add the app created, and it should look like this:

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

Edit the urls.py file in the project directory (hello/urls.py) to get the following content:

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

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

create a directory for core templates:

$ mkdir -p core/templates/core

create a core template called hello.html, with the content

<p>Hello World</p>

Create (or edit), in the reaiz of the core app, the file urls.py with the content

from django.conf.urls import url
from core .views import hello

urlpatterns = [
    url(r'^hello/$', hello,  name='hello'),
]

Create your views (views.py) in the app directory (core) with the content:

from django.shortcuts import render
def hello(request):
    return render(request, 'core/hello.html')

Finally run the project, point the browser to http://127.0.0.1:8000/core/hello/ and see Hello World.

Instead of doing it that way:

from django.conf.urls import url, include
from django.contrib import admin
from simplemooc.core import views
from simplemooc.core import urls

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

Remove the quotes and knife like this:

from django.conf.urls import url, include
from django.contrib import admin
from simplemooc.core import views
from simplemooc.core import urls

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

Why once you’ve imported them You can pass them without quotation marks
