Im quite new in django ... but I followed this tutorial: https://docs.djangoproject.com/en/1.9/ref/contrib/admin/

I dont have any custom AdminSites and custom AdminModels.

I already googled about this problem but still I cannot solve it for my case in any way. Can you help ?

here is my settings.py:

Answer 1

To resolve this go to settings.py where there is new-style MIDDLEWARE (introduced in Django 1.10)

Change that to old-style MIDDLEWARE_CLASSES

https://docs.djangoproject.com/en/stable/topics/http/middleware/#upgrading-pre-django-1-10-style-middleware

Answer 2

I found the answer. The variable name on:

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

MIDDLEWARE is the new-style configuration introduced in Django 1.10. Change the name to MIDDLEWARE_CLASSES and now it works.

So now the code is:

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.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

Answer 3

In case anyone is having this problem with Django 2.0, the following configuration with new-style MIDDLEWARE seems to work (docs here):

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

Answer 4

In case anyone is having the same problem in django 2.0.2 or later,

just update

MIDDLEWARE_CLASSES = (
'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',
'django.middleware.security.SecurityMiddleware',
)

with

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

It worked for me cause i created my project with django 1.0.x but later updated to django 2.0.2
