Python MongoDB JSON schema validator “unresolved reference”

Question

I am relatively new to both Python and MongoDB, I am using python to set up a MongoDB database and create a collection with schema validation. However, when I create the collection as specified in the MongoDB documentation like so:

db.create_collection("collection", {
        validator: {
            "$schema": "schema_stuff",
            "property1":"..."
        }

Pycharm throws an error saying: "Unresolved reference 'validator' "

I suspect it may have something to do with my import but I'm not sure.

from pymongo import MongoClient

Any ideas why this might be happening?

Answer 1

It happens because what you try to put into validator is a dictionary and validator is supposed to be a variable/object which is not known to Python. correct is to have 'validator' or "validator" instead of validator .

Correct query to create collection with validator should be like this:

validator = {'validator': {'your validation stuff'}}    
db.create_collection("collection", validator=validator)

Or like this:

db.create_collection("collection", validator={'validator': 'your validation stuff'})
