django-mongoengine 0.6.0b4

Connecting

In your settings.py file, add following lines:

MONGODB_DATABASES = {
    "default": {
        "name": database_name,
        "host": database_host,
        "password": database_password,
        "username": database_user,
        "tz_aware": True, # if you using timezones in django (USE_TZ = True)
    },
}

INSTALLED_APPS += ["django_mongoengine"]

Documents

Inhherit your documents from django_mongoengine.Document, and define fields using django_mongoengine.fields.:

from django_mongoengine import Document, EmbeddedDocument, fields

class Comment(EmbeddedDocument):
    created_at = fields.DateTimeField(
        default=datetime.datetime.now, editable=False,
    )
    author = fields.StringField(verbose_name="Name", max_length=255)
    email  = fields.EmailField(verbose_name="Email")
    body = fields.StringField(verbose_name="Comment")

class Post(Document):
    created_at = fields.DateTimeField(
        default=datetime.datetime.now, editable=False,
    )
    title = fields.StringField(max_length=255)
    slug = fields.StringField(max_length=255, primary_key=True)
    comments = fields.ListField(
        fields.EmbeddedDocumentField('Comment'), required=False,
    )

Sessions

Django allows the use of different backend stores for its sessions. MongoEngine provides a MongoDB-based session backend for Django, which allows you to use sessions in your Django application with just MongoDB. To enable the MongoEngine session backend, ensure that your settings module has 'django.contrib.sessions.middleware.SessionMiddleware' in the MIDDLEWARE_CLASSES field and 'django.contrib.sessions' in your INSTALLED_APPS. From there, all you need to do is add the following line into your settings module:

SESSION_ENGINE = 'django_mongoengine.sessions'
SESSION_SERIALIZER = 'django_mongoengine.sessions.BSONSerializer'

Django provides session cookie, which expires after `SESSION_COOKIE_AGE` seconds, but doesn’t delete cookie at sessions backend, so 'mongoengine.django.sessions' supports mongodb TTL.
