Connecting to a local MongoDB and MongoDB Atlas

Question

I have a local app, that uses MongoDB Community Server, and I intend to deploy it to GCloud. I have also created a MongoDB Atlas DB, collection and document.

How do I configure my local version to use Community Server and the production version to use Atlas?

I've searched around, but I guess I don't know what to look for.

Secondly, is that the right method to go down?

You can use python configParser for this task. Create a config.ini file as fillow.

[dev]
mongo_url = ...        
          
[prod]
mongo_url = ...

In the file where you want to get the mongo url add following lines.

import configparser
import sys
config = configparser.ConfigParser()
config.read('config.ini')
version = sys.argv[0]
mongo_url = config[version].mongo_url

Then you can pass version (dev/prod) as a argument as follows.

py app.py dev
