Django mongoengine save data

Question

In my Django project i have used Mysql and MongoDB as two database. And defined settings file like this.

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'db_name'
},
'mongo_db': {
    'ENGINE': 'django_mongodb_engine',
    'NAME': '****',

},

}

I have defined all my models like this

class EntityType(Document):
  entity_type = fields.StringField()

Now when i want to store data in EntityType using Django shell its throwing error ConnectionError: You have not defined a default connection

Please suggest what i am doing wrong

Edit

Have i added wrong engine in mongo_db database connection.I think i got confused between mongoengine and django-mongodb-engine

Answer 1

Let's say you do:

entity_type = EntityType(....)
entity_type.save(using='mongo_db')

This should work

Answer 2

You can connect your database using mongoengine

from mongoengine import connect
connect(alias='alias_name', db='db_name', host='localhost', 
username='your_username', password='password_of_your_username', 
authentication_source='admin')
