Re: TypeError at /users/login/ login() got an unexpected keyword argument 'template_name'

Hi Jason, 

Thank !

my urls.py in /users looks like this

This is the error I get with amusement.

How to change the old import? I suppose this is the way. Because the admin is imported from django. 

"""Defines URL patterns for users"""

from django.conf.urls import url
from . import views
# from django.contrib.auth import login
from django.contrib.auth.views import LoginView

app_name='users'


urlpatterns = [
              # Login page
url('login/', LoginView, {'template_name': 'users/login.html'}, name='login'),
# Logout page
url('logout/', views.logout_view, name='logout'),
]

TypeError at /users/login/

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 page generated by the handler for this status code.
