MongoEngine is a Python Object-Document Mapper (ODM) built on top of PyMongo for working with MongoDB. It provides schema-based document models, querying, signals, and file storage in a declarative, ORM-like API.

Use cases

• model MongoDB documents with Python classes
• query MongoDB with a pythonic API instead of raw queries
• add schema validation to a schemaless MongoDB database
• use MongoDB as the data layer for a Django or Flask app
• store and retrieve files with GridFS from Python
• define document fields with types, defaults, and required validation

When to choose

• you use MongoDB from Python and want structured, validated document models
• you prefer declarative schemas and queryset APIs over raw PyMongo calls
• you want a mature, MIT-licensed ODM with Django integration support

When to avoid

• you use a relational database instead of MongoDB
• you need maximum performance and minimal abstraction - use PyMongo directly
• you need an async-first ODM for asyncio applications
