How to connect Django ORM to mongo atlas?

Question

I am trying to connect my django instance to a mongo db cluster using django. I have checked from various sources and the way it is getting closer to work is:

Answer 1

Simplest and correct solution:

Step 1: Install djongo and dnspython

pip install djongo

pip install dnspython

Step 2: Changes in settings.py:

DATABASES = {
"default": {
    "ENGINE": "djongo",
    "CLIENT": {
        "host": "mongodb+srv://<username>:<password>@<cluster_name>.mongodb.net/?retryWrites=true&w=majority",
        "username": "<username>",
        "password": "<password>",
        "name": "<database_name>",
        "authMechanism": "SCRAM-SHA-1",
    },
}}

Answer 2

Install djongo package using pip install djongo.

Make sure you import following module:

import urllib

Setup database settings.

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': '<db_name>',
        'HOST': "mongodb+srv://<db_username>:" +
                urllib.parse.quote_plus("<db_password>") +
                "@........mongodb.net/test?retryWrites=true&ssl=true&ssl_cert_reqs=CERT_NONE&w=majority",
    }
}

Substitute db_username, db_name and db_password with your credentials.

Also edit the host name given by Mongo Atlas.

Got this working without any hack as follows:

1. Install pip install dnspython.
2. Update settings.py with the following,

'default': {
        'ENGINE': 'djongo',
        'NAME': '<dbname>',
        'CLIENT': {
            'host': "mongodb+srv://<username>:" + quote_plus('<password>') + "@<cluster-name>.mongodb.net/test?retryWrites=true&w=majority"
        },   
    }

3. Run python manage.py makemigrations
4. Run python manage.py migrate

Answer 4

I just setup Djongo and MongoDB Atlas with the following:

DATABASES = {
        'default': {
        'ENGINE': 'djongo',
        'NAME': '<db name>',
        'HOST': 'mongodb+srv://<db username>:<db password>@....mongodb.net/test?retryWrites=true',
        'USER': '<db username>',
        'PASSWORD': '<db password>',
    }
}

Hope that helps!

Answer 5

I have managed to connect to mongo atlas with djongo by using the snippet from @Market Ahead here

It looks like they dont want the password to have weird characters inside. In such case, even escaping is not working optimally.
