Comment:
This is an expected behavior because `choice` is an optional in your
pattern, if you want to specify default parameter for you views you should
use two patterns:
{{{
urlpatterns = [
url(r'^$', routing_example),
url(r'^(?:(?P<choice>(this|that)))?$', routing_example),
]
}}}
See [https://docs.djangoproject.com/en/3.0/topics/http/urls/#specifying-
defaults-for-view-arguments Specifying defaults for view arguments]. Trac
