Djongo not writing the table using manage.py migrate

Question

I am very new at this and am trying to connect my django project with my mongodb using djongo.

I've set up mongo atlas and give myself the admin role.

to create a new project:

django-admin startproject mysite

I've created a database with nothing in it called demo_db that has no data written Then I change the settings.py database session into:

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'demo_db',
        'HOST': 'mongodb+srv://louisa:<password>@cluster0.ya1jd.mongodb.net/demo_db?retryWrites=true&w=majority',
        'USER': 'louisa',
        'PASSWORD': '<password>',
    }
}

I am running atlas version 4.2. When I save the settings.py and run

python manage.py migrate

This is the output message:

Everything seems fine, but when I take a look at the database via compass, or even on atlas, there is no new data table written at all rather than initiating some table.

The strangest thing is that when I later create admin profile or add data into the mongodb, even though it doesnt show anything on the console, I am able to get access to it through the django command.

I tried to write an object or two using pymongo without any problem, and i can use the host url to connect my local compass to my atlas, so this is not likely to be the problem either. Not sure what had gone wrong here.
