無法導入LoginView？

我正在學習一些關於Django 1.9的東西，我想創建一個登錄表單，但使用基於類的視圖。無法導入LoginView？

這是MI視圖代碼：

from django.shortcuts import render 

from django.contrib.auth.views import LoginView 

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

這是我的網址代碼：

from django.conf.urls import url, include 

from .views import AlumnoLoginView 

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

這使得一個錯誤：

ImportError: cannot import name LoginView

但如果我刪除裏面的代碼沒有任何反應。

這是完全錯誤跟蹤（弗朗索瓦變化）：

    from django.contrib.auth.views import LoginView as BaseLoginView 
ImportError: cannot import name LoginView

有什麼不對？我如何修復它？謝謝:)

你使用/進口原裝LoginView在你的網址或其他地方？嘗試'從django.contrib.auth.views導入LoginView作爲BaseLoginView' –

此外，你可以粘貼完整的錯誤跟蹤？ –

我讀了類似的[鏈接]（http://stackoverflow.com/questions/5238658/django-cannot-import-name）關於循環導入，但我不明白如何解決它@弗朗索瓦 – plafhz

在django.contrib.auth.views中沒有視圖叫做LoginView 我認爲你需要。

從django.contrib.auth.views導入登錄

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

基於類的視圖LoginView和LogoutView被引入上的Django 1.11和基於函數的視圖的登錄「和「登出」是deprecated從那時起。

您可以使用基於類的意見LoginView和LogoutView這樣的：

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


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

]
