Python Django:'；WSGIRequest&x27；对象没有属性'；用户'；？-认证中间件&；SessionAuthenticationMiddleware正在按顺序运行

尝试访问django管理面板时出现以下错误

Environment:

Request Method: GET
Request URL: http://localhost:8000/admin/

Django Version: 1.9.8
Python Version: 2.7.10
Installed Applications:
['django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'bookapp']
Installed Middleware:
['django.middleware.common.CommonMiddleware',
 'django.middleware.csrf.CsrfViewMiddleware']

Traceback:

Exception Type: AttributeError at /admin/
Exception Value: 'WSGIRequest' object has no attribute 'user'

这是我在settings.py中的中间件设置

MIDDLEWARE_CLASSES = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

我也尝试过清除缓存，比如清除迁移和删除数据库。但这对我不起作用

有人知道这里有什么问题吗？

将名称

中间件更改为
中间件\u类
请显示完整的回溯：单击“切换到复制和粘贴视图”在调试页面中，将文本粘贴到此处。@DanielRoseman编辑该错误页面告诉您没有安装这些中间件类；您只有普通的和csrf的。你确定你有正确的设置文件吗？是的。我也发布了一些课程，我知道你有。但是错误页面清楚地显示了与您声明的列表不同的列表。所以，你的设置没有被使用。@ PinankLakhani，你应该考虑批准这个答案。
