ImproperlyConfigured error when logging into django site while using mongoengine

Question

I am using Django in conjunction with MongoDB using mongoengine. I was following the tutorial on https://docs.djangoproject.com/en/1.7/intro/tutorial02/ and therefore wanted to create a superuser and log in. Creation worked without problem appearantly. However when I tried to log in, I was greeted by the following site:

enter image description here

I suppose this has to do with my initialization of the database using the dummy database in the settings.py. However I was told using mongoengine requires to do it this way and it did not cause problems earlier. Anyway: here is the content of my settings.py

Kindly configure the following settings in setting.py file

import mongoengine
DATABASES = {
    'default': {
        'ENGINE': '',
    },
}

SESSION_ENGINE = 'mongoengine.django.sessions' # optional

_MONGODB_USER = 'mongouser'
_MONGODB_PASSWD = 'password'
_MONGODB_HOST = 'thehost'
_MONGODB_NAME = 'thedb'
_MONGODB_DATABASE_HOST = \
    'mongodb://%s:%s@%s/%s' \
    % (_MONGODB_USER, _MONGODB_PASSWD, _MONGODB_HOST, _MONGODB_NAME)

mongoengine.connect(_MONGODB_NAME, host=_MONGODB_DATABASE_HOST)

AUTHENTICATION_BACKENDS = (
'mongoengine.django.auth.MongoEngineBackend',
)

I hope the above solution will resolve your issue.

Thanks for the quick answer, but appearantly this did not fix everything. I think this has to do with the fact that my database is named differently. Maybe I need to adjust the code you have given me. When trying to start the server I now get the error message: raise ConnectionError("Cannot connect to database %s :\n%s" % (alias, e)) mongoengine.connection.ConnectionError: Cannot connect to database default : [Errno 11001] getaddrinfo failed – Hagadol Dec 24 '14 at 11:13
hmm... it does not fix anything. – Saad Bin Shahid Oct 18 '15 at 21:49

what to do if database-engine not needed

default database is used by some of the default authentication APIs used in Middleware-Apps.

try to make your MIDDLEWARE_APPS tuple as follows:

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',
)

I am just a beginner, so if any more errors come around please do comment.

This solution breaks the default Admin Panel backend provided by Django. I'm trying to find a work around for the same.

Redirecting to a different view in urls.py for admin page may help though
