Question 1

How to use Beanie with FastAPI for authentication?

Accepted Answer

Beanie integrates smoothly with FastAPI using async endpoints; define Document classes with Pydantic models and use Beanie's async methods in route handlers. Example projects like fastapi-beanie-jwt show JWT auth implementations.

Question 2

Beanie vs Motor for async MongoDB in Python?

Accepted Answer

Beanie is an ODM with Pydantic models and high-level abstractions, while Motor is a low-level async driver. Choose Beanie for type-safe modeling and reduced boilerplate, but Motor for direct control over raw queries.

Question 3

Can Beanie handle complex MongoDB aggregation pipelines?

Accepted Answer

Yes, Beanie supports aggregation through its query builder, but for highly complex pipelines, you may need to fall back to raw PyMongo queries. The documentation includes examples for basic aggregations.

Question 4

How to perform data migrations with Beanie?

Accepted Answer

Beanie provides built-in migration tools; create migration classes with upgrade/downgrade methods and apply them via CLI. The docs offer tutorials on managing schema changes over time.

Question 5

Is Beanie good for real-time apps with WebSockets?

Accepted Answer

Yes, Beanie's async design fits well with real-time applications; it handles concurrent operations efficiently when paired with async frameworks like FastAPI and WebSocket handlers, as seen in the activity log example.

Question 6

Does Beanie support transactions in MongoDB?

Accepted Answer

Beanie supports MongoDB transactions through its async session management, but it requires careful handling within document methods. The documentation covers transaction usage for atomic operations.
