Django 3.0 tutorial - mysite/URL not working - django

Question

I have completed all seven steps of the Writing your first Django app tutorial for 3.0. Everything works great, except the base site URL for 'mysite' at http://127.0.0.1:8000/. At the beginning of the tutorial, it worked, but it stopped working as I progressed/at the end. http://127.0.0.1:8000/admin/ works fine. Can anyone tell me what I'm doing wrong?
Based on how the tutorial is structured, i.e. "add this and that and this and that," etc., that I overwrote something.
Here is the error I'm receiving in my browser:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
polls/
admin/
The empty path didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
Here is the error I'm receiving in Terminal:
Not Found: /
[20/Jun/2020 11:01:22] "GET / HTTP/1.1" 404 2027
Here is my polls/urls.py file:
from django.urls import path
from . import views
app_name = 'polls'
urlpatterns = [
path('', views.IndexView.as_view(), name='index'),
path('<int:pk>/', views.DetailView.as_view(), name='detail'),
path('<int:pk>/results/', views.ResultsView.as_view(), name='results'),
path('<int:question_id>/vote/', views.vote, name='vote'),
]
Here is my mysite/urls.py file:
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
]
Here is TEMPLATES in mysite/settings.py:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]

Answer from expert Willem Van Onsem
1. Edit mysite/urls.py
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('', include('polls.urls')), # no /polls/ prefix
path('admin/', admin.site.urls),
]
2. Run python manage.py runserver

Answer 1

Can anyone tell me what I'm doing wrong?
All your paths for the poll app are here prefixed by polls/, since you wrote:
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
]
You thus can visit the IndexView by fetching the http://127.0.0.1:8000/polls/ URI. If you do not want to prefix the urls, you can rewrite the root urls.py to:
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('', include('polls.urls')), # no /polls/ prefix
path('admin/', admin.site.urls),
]
Then you can simply visit http://127.0.0.1:8000/.
