This lesson is part of Python · All levels

Summary

This lesson explains how to insert documents into MongoDB collections using insert_one and insert_many. Every document is a Python dictionary, and the server will create a unique field ID if you don't specify it. The insertion result returns inserted_id that can be used to retrieve the document.

Key points

Insert_one(add one document, insert_many(add multiple documents at once.
Field _id is automated by MongoDB and serves as a unique document marker.
The insert_many result is InsertManyResult which contains a list of inserted_ids.
Documents may have different fields of each other in the same collection.
The insert doesn't require commits like SQL, storage takes place directly on the server.
