Реверс для 'extranet.views.uutiset_paasivu' не найден. 'extranet.views.uutiset_paasivu' не является действительным именем функции представления или шаблона

Я пытаюсь обновить проект django с django1.4/python 2.7 до django2.2/python3.7. Теперь я запутался в трассировке после запуска сервера pythan manage.py (и после перехода на страницу /uutiset/):

смотрите urls.py, views.py, uutiset_all.html, paasivu.html и base.html ниже

urls.py:

from django.conf.urls import url, include
from django.contrib.auth import views as auth_views
from extranet.views import *
from django.conf import settings
from django.contrib import admin
from django.urls import path
from django.views.static import serve
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = [
    url(r'^uutiset/', uutiset),,
     ]

extranet/views.py:

    t = loader.get_template("uutiset_all.html")
