How to configure settings.py for mongodb ?

Question

I created django web app that use mongo database , I connet to mongo with pymongo

 def load_database():
    mongo = pymongo.Connection('127.0.0.1')
    db = mongo['database']

when I tried to load my web app , I get error

Exception Type:

ImproperlyConfigured



Exception Value:

settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details. 


Exception Location:

Python-2.7/lib/python2.7/site-packages/django/db/backends/dummy/base.py in complain, line 15

it looks that settings.py is wrong configured , here is my settings.py :

MANAGERS = ADMINS

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or     
'NAME': '',                      # Or path to database file if using sqlite3.
 # The following settings are not`enter code here` used with sqlite3:
'USER': '',
'PASSWORD': '',
'HOST': '',                      # Empty for localhost through domain sockets or   '
'PORT': '',                      # Set to empty string for default.
}
}

Can someone tell me what is wrong ? when I load homepage that don't coneect to mongo , only static files it loads fine , when I click on buttom on hoempage that gets data from mongo database and print out that data , I get this error . Also I tried python manage.py syncdb but gets error : ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

For proper working of mongoDB you should install these packages: Django-nonrel, djangotoolbox, mongodb-engine for Django.

And after that you can edit settings

DATABASES = {
   'default' : {
      'ENGINE' : 'django_mongodb_engine',
      'NAME' : 'my_database'
   }
}

If you are using pymongo directly, you can just leave out the entire DATABASES variable from settings.py.

If you don't want to use pymongo directly, consider looking into mongoengine.

I use pymongo diretly but it looks that problem is not in pymongo, I just figure our it now, I use request.session , so that is why I get error, to use seasion variable I need to syncdb database , do you know how to do it ?

OK you need to specify a database backend to store the session data. You can use MongoDB for this using Mongoengine (see section 6.4).
