Documentation Regression for Tutorial 03

[Paul]

It looks like this issue may have been fixed in the past, but documentation version 1.7 onward do not mention this. It is also not mentioned in Tutorial 04.
The tutorial is missing a reference to adding the namespace to the mysite/urls.py as follows:

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

 urlpatterns = [
-    path('polls/', include('polls.urls')),
+    path('polls/', include('polls.urls', namespace="polls")),
     path('admin/', admin.site.urls),
 ]

Without this change, it gives an NoReverseMatch error, "polls" is not a registered namespace

Could the tutorial be updated to include this change?

This suggestion is incorrect. You may be missing app_name = 'polls' in polls/urls.py.

Here is my polls/url.py:

from django.urls import path

from . import views

app_name = 'polls'
urlpatterns = [
        # /polls/
        path('',views.index, name='index'),
        # /polls/5/
        path('<int:question_id>/', views.detail, name='detail'),
        # /polls/5/results/
        path('<int:question_id>/results/', views.results, name='results'),
        # /polls/5/vote/
        path('<int:question_id>/vote/', views.vote, name='vote'),
]

And python -m django --version yields 2.0.3

arrow (0.12.1)
blessed (1.14.2)

Not sure what's going on, but it's working now following the existing tutorial steps.
