无法导入LoginView？

我正在学习一些关于Django 1.9的东西，我想创建一个登录表单，但使用基于类的视图。无法导入LoginView？

这是MI视图代码：

from django.shortcuts import render 

from django.contrib.auth.views import LoginView 

class AlumnoLoginView(LoginView): 
    template_name = "alumno/login.html" 
    redirect_authenticated_user = True

这是我的网址代码：

from django.conf.urls import url, include 

from .views import AlumnoLoginView 

app_name = 'alumno' 
urlpatterns = [ 
    url(r'^login/$', AlumnoLoginView.as_view(), name="login"), 
]

这使得一个错误：

ImportError: cannot import name LoginView

但如果我删除里面的代码没有任何反应。

这是完全错误跟踪（弗朗索瓦变化）：

ImportError: cannot import name LoginView

有什么不对？我如何修复它？谢谢:)

你使用/进口原装LoginView在你的网址或其他地方？尝试'从django.contrib.auth.views导入LoginView作为BaseLoginView' –

此外，你可以粘贴完整的错误跟踪？ –

我读了类似的[链接]（http://stackoverflow.com/questions/5238658/django-cannot-import-name）关于循环导入，但我不明白如何解决它@弗朗索瓦 – plafhz

在django.contrib.auth.views中没有视图叫做LoginView 我认为你需要。

从django.contrib.auth.views导入登录

LoginView仅在2015年8月的Django的'dev'发行版中 - 它在1.9或1.10.0中不可用。 – Gregarious

基于类的视图LoginView和LogoutView被引入上的Django 1.11和基于函数的视图的登录“和“登出”是deprecated从那时起。

您可以使用基于类的意见LoginView和LogoutView这样的：

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


urlpatterns = [ 
    url(r'^login/$', LoginView.as_view(template_name='...'), name="login"), 

]
