Django: Class-based views, URL and template_name

I am trying to use something like polls:detailin a class-based view, such as this:

class QuestionDetail(DetailView):
    template_name = 'polls:result'

However, I get a TemplateDoesNotExist at /polls/2/result polls:result error...

The urls.py is:

from django.conf.urls import url
from polls.views import IndexView, DetailView, ResultsView

from . import views


app_name = 'polls'
urlpatterns = [
    url(r'^$', IndexView.as_view(), name='index'),
    url(r'^(?P<pk>\d+)/$', DetailView.as_view(), name='detail'),
    url(r'^(?P<pk>\d+)/result$', ResultsView.as_view(), name='result'),
    url(r'^(?P<pk>\d+)/vote$', views.vote, name='vote'),
]


I guess the main question is, how do I use the names of URLs in class-based views, instead of explicitly providing the template name, such as polls/question_results.html?

Is there anything other than template_name?

I was reading that it's a good practice to use names in URLS so in case the URL itself changes, the rest of the code still works, so that's what I'm trying to do.

Url name and template name are very absolutely things.

template_name is a path to the .html file.

Url's name parameter you can use to reverse url from name using django.urls.reverse

You can use the name of URL like this: django.urls.reverse('polls:detail', args=[object.id])

And you have to change the template_name settings as well and to create a template detail.html in your current template folder.

template_name = 'polls/detail.html'
