The correct place is:

* In the key `content`, that has as value another JSON object (`dict`) that contains:
    * A key with the media type, e.g. `application/json`, that contains as value another JSON object, that contains:
        * A key `schema`, that has as the value the JSON Schema from the model, here's the correct place.

Si vous ne déclarez pas de modèle de réponse, FastAPI utilise le `jsonable_encoder` expliqué dans [Encodeur compatible JSON](../tutorial/encoder.md) et le place dans une `JSONResponse`.

Vous pouvez également créer directement une `JSONResponse` et la renvoyer.
