Django App Structure

Create a new app:

python3 manage.py startapp demoapp

edit the views.py:

from django.http import HttpResponse
 
def index(request):
	return HttpResponse("Hellow from the demo view app")

create urls.py file in the demoapp directory:

from django.urls import path
from . import views
 
urlpattern = [
	path('', views.index, name='index')
]

update the urls.py in the demoproject:

from django.contrib import admin
from django.urls import path, include
  
urlpatterns = [
	path('admin/', admin.site.urls),
	path('demoapp/', include('demoapp.urls'))
]

update the settings.py file:

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

after performing these the new folder structure will be the following one:
