Vous pouvez étendre le schéma OpenAPI pour une *opération de chemin* en utilisant le paramètre `openapi_extra`.

### Extensions OpenAPI

Cet `openapi_extra` peut être utile, par exemple, pour déclarer [OpenAPI Extensions](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#specificationExtensions) :

```Python hl_lines="6"

                                "schema": IsDict(
                                    {
                                        "$ref": "#/components/schemas/Item",
                                        "examples": [
                                            {
                                                "name": "Foo",
                                                "description": "A very nice Item",

                                "schema": IsDict(
                                    {
                                        "$ref": "#/components/schemas/Item",
                                        "examples": [
                                            {
                                                "name": "Foo",
                                                "description": "A very nice Item",

Dans l'exemple précédent, les opérations de routage attendaient un body JSON avec les attributs d'un `Item`, par exemple :

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

Mais vous pouvez également déclarer plusieurs paramètres provenant de body, par exemple `item` et `user` simultanément :
