Setting up MongoDB + Django

Question

I am new to Mongo DB and Django. I've been trying to use Mongo DB as my primary Database for Django. I've installed MongoDB and Django-nonrel as per the following link:

Django - MongoDB setup

The version of django-nonrel, i am using is 1.7. Clone link to it:

pip install git+https://github.com/django-nonrel/[email protected]

After following all steps, my settings.py in the django project file looks something like this:

DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'blink',
        'USER': '',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': 1234,
    }
}

INSTALLED_APPS = (
    'djangotoolbox',
)

But while running the manage.py using the following command:

python manage.py runserver

I am getting an error like this,

System check identified no issues (0 silenced).

I am not able to understand what the error is. Can somebody please help.?

Are you using Python 2 or Python 3?

It seems that you are using Python 3. But django-mongodb-engine, on which django-nonrel depends, doesn't even support Python 3 yet.

The syntax error above is actually valid in py3, but not in py2. Thus the error.

Perhaps you should consider using py2 for this project.

what about mongo engine? Does that support py3?

ljk321 Over a year ago

This mongo engine(the one you used above) depends on Django-nonrel. So I don't think it supports py3, either.

In 2021 MongoDB supports Py3 and Django with 3 Engines. Its PyMongo, MongoEngine and Djongo.

PyMongo is the standard driver through which MongoDB can interact with Django.
MongoEngine is similar to a Object-Relational-Mapper in relational databases
djongo transpiles all the SQL queries to MongoDB syntax queries.
