python 關於django 2.X from django.contrib.auth.views import login

在學習注冊用戶的過程中，視圖中下面的代碼

from django.contrib.auth.views import login

啟動django服務時，報錯：

ImportError: cannot import name 'login' from 'django.contrib.auth.views'

改為

from django.contrib.auth import login

django服務啟動正常，但在點擊login鏈接時又出現如下錯誤

TypeError at /users/login/
login() got an unexpected keyword argument 'template_name'
Request Method: GET
Request URL: http://127.0.0.1:8000/users/login/
Django Version: 2.1.4
Exception Type: TypeError
Exception Value:
login() got an unexpected keyword argument 'template_name'

經過多方查找，解決辦法如下：

from django.contrib.auth.views import LoginView
from . import views

app_name = 'users'

urlpatterns = [
#登錄頁面
#url(r'^login/$', login, {'template_name': 'users/login.html'}, name = 'login'),
url(r'^login/$', LoginView.as_view(template_name='users/login.html'), name="login"),
]
