Django admin error 'WSGIRequest' object has no attribute 'user

Question

I am practicing Django, and when i try to go to http://localhost/admin/ i get the below error, I have checked settings.py and MIDDLEWARE_CLASSES does exist, is there any other reason why i am getting this message.

content of MIDDLEWARE in settings

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 has dropped support for old-style middleware classes in MIDDLEWARE_CLASSES changelog, last item

Upgrading is straightforward if you use only standard middleware, explained in Upgrading pre-Django 1.10-style middleware. Often just renaming MIDDLEWARE_CLASSES to MIDDLEWARE and removing 'django.contrib.auth.middleware.SessionAuthenticationMiddleware' is enough.

You must also make sure django.contrib.auth is installed properly. In addition to SessionMiddleware, which you already have, you should add django.contrib.auth.middleware.AuthenticationMiddleware to the MIDDLEWARE setting.

Answer 2

My original Django version was 1.9 . I ran into the same issue after upgrading to version 2.0.5. Renaming MIDDLEWARE_CLASSES to MIDDLEWARE and removing 'django.contrib.auth.middleware.SessionAuthenticationMiddleware' in settings.py did the job
