Setting up MongoDB + Django

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/django@nonrel-1.7

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).

    SyntaxError: invalid syntax

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

Answer

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.
