我正在按照网站上的教程安装Openstack Stein Horizon服务(仪表板(。我遇到了一个由Django版本引起的错误，并使用以下解释进行了修复：从Django-string_conat切换到format_lazy。
出现的下一个问题是AttributeError：模块"django.contrib.auth.views"没有属性"login">，我在谷歌上搜索了一下，结果再次发现django版本不兼容。我在这里遵循了这样的解释：AttributeError：模块Djang.contrib.auth.views没有属性

Thks。
您确实将django.contrib.auth.views模块导入为auth_views，而不是从该模块导入LoginView、LogoutView等。例如，您可以使用auth_views.LoginView:
from django.contrib.auth import views as auth_views
urlpatterns = [
url(r"^login/$",auth_views.LoginView.as_view(), name='login'),
url(r"^logout/$",auth_views.LogoutView.as_view(), name='logout'),
url(r'^switch/(?P<tenant_id>[^/]+)/$', views.switch,
name='switch_tenants'),
url(r'^switch_services_region/(?P<region_name>[^/]+)/$',
views.switch_region,
name='switch_services_region'),
url(r'^switch_keystone_provider/(?P<keystone_provider>[^/]+)/$',
views.switch_keystone_provider,
name='switch_keystone_provider')
]或者您可以从该模块导入LoginView和LogoutView：
from django.contrib.auth.views import LoginView, LogoutView
urlpatterns = [
url(r"^login/$", LoginView.as_view(), name='login'),
url(r"^logout/$", LogoutView.as_view(), name='logout'),
url(r'^switch/(?P<tenant_id>[^/]+)/$', views.switch,
name='switch_tenants'),
url(r'^switch_services_region/(?P<region_name>[^/]+)/$',
views.switch_region,
name='switch_services_region'),
url(r'^switch_keystone_provider/(?P<keystone_provider>[^/]+)/$',
views.switch_keystone_provider,
name='switch_keystone_provider')
]
