## Fortgeschrittene Beschreibung mittels Docstring { #advanced-description-from-docstring }

Sie können die verwendeten Zeilen aus dem Docstring einer *Pfadoperation-Funktion* einschränken, die für OpenAPI verwendet werden.

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

Esto significaría que **FastAPI** esperaría un cuerpo similar a:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

## Description avancée de docstring

Vous pouvez limiter le texte utilisé de la docstring d'une *fonction de chemin* qui sera affiché sur OpenAPI.
