Question

我正在练习Django，当我尝试去http://localhost/admin/时我得到以下错误，我检查了settings.py和MIDDLEWARE_CLASSES确实存在，是否还有其他原因我收到此消息。< / p>

设置中的MIDDLEWARE内容

MIDDLEWARE = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
)

Answer 1

Django 2.0已放弃对MIDDLEWARE_CLASSES changelog, last item

中旧式中间件类的支持

如果仅使用标准中间件，则升级很简单，如Upgrading pre-Django 1.10-style middleware中所述。通常只需将MIDDLEWARE_CLASSES重命名为MIDDLEWARE并删除'django.contrib.auth.middleware.SessionAuthenticationMiddleware'即可。

您还必须确保django.contrib.auth is installed properly。除了您已有的SessionMiddleware之外，您还应将django.contrib.auth.middleware.AuthenticationMiddleware添加到MIDDLEWARE设置。

Answer 2

我原来的Django版本是1.9。升级到2.0.5版后，我遇到了同样的问题。将MIDDLEWARE_CLASSES重命名为MIDDLEWARE并删除＆＃39; django.contrib.auth.middleware.SessionAuthenticationMiddleware＆＃39;在settings.py中完成了这项工作
