ImproperlyConfigured error when logging into django site while using mongoengine - django

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:
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
"""

Answer 1

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.

Answer 2

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
