How to Add Roles to a User in MongoDB via Python (Pymongo)

Managing user roles in MongoDB is a crucial task that helps maintain database security and organization. If you're trying to add new roles to an existing user using Python's Pymongo library, you might have run into some challenges. This guide will explain the problem you might encounter and provide a straightforward solution to effectively add roles to users.

Understanding the Problem

When working with MongoDB, you may want to assign users specific roles that determine their permissions on the database. However, you might face an error while trying to use the db._create_or_update_user() method, as one user did. This method may not provide the flexibility you need, particularly if you're encountering an error like:

The challenge here is to find a reliable method to grant roles without running into positional argument issues.

Solution: Using MongoDB Commands with Pymongo

The recommended way to add roles without encountering positional argument issues is to directly use MongoDB commands. In this case, we will utilize the grantRolesToUser command, which is more straightforward and does not require unnecessary additional arguments.

Step-by-Step Guide

Here's how to add roles to a user in MongoDB using Pymongo:

Import Necessary Libraries
