How to run the getrole command in pymongo?
To run the getRole command in pymongo, you can use the following code snippet:
1 2 3 4 5 6 7 8 9 10 11 12 |
from pymongo import MongoClient # Connect to MongoDB client = MongoClient('mongodb://localhost:27017') # Get the admin database db = client.admin # Run the getRole command result = db.command('getRole', '<role_name>') print(result) |

How to handle exceptions when running the getrole command in pymongo?
When running the getrole command in PyMongo, you can handle exceptions by using a try-except block. Here is an example of how you can handle exceptions when running the getrole command:
1 2 3 4 5 6 7 8 9 10 11 12 |
from pymongo import MongoClient from pymongo.errors import OperationFailure # Connect to the MongoDB server client = MongoClient('mongodb://localhost:27017') try: # Run the getrole command to retrieve a role role = client.admin.command('getRole', 'role_name') print(role) except OperationFailure as e: print(f"An error occurred: {e.code} - {e.details}") |
In the above code snippet, we use a try-except block to catch any OperationFailure exceptions that may occur when running the getrole command. Inside the except block, we print out the error code and details to help identify the cause of the exception.
You can customize the error handling logic inside the except block as needed for your application. Additionally, make sure to handle exceptions appropriately based on the specific requirements and error scenarios in your application.
