# Configurer les chemins d'accès { #path-operation-configuration }

Vous pouvez passer plusieurs paramètres à votre *décorateur de chemin d'accès* pour le configurer.

/// warning | Alertes

Notez que ces paramètres sont passés directement au *décorateur de chemin d'accès*, et non à votre *fonction de chemin d'accès*.

Nesse caso você tem:

* `ItemsService`
* `UsersService`

### Nomes dos métodos do cliente { #client-method-names }

Agora os nomes dos métodos gerados como `createItemItemsPost` não parecem muito “limpos”:

```TypeScript
ItemsService.createItemItemsPost({name: "Plumbus", price: 5})

## Importer `Field` { #import-field }

D'abord, vous devez l'importer :

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning | Alertes

Notez que `Field` est importé directement depuis `pydantic`, et non depuis `fastapi` comme le sont les autres (`Query`, `Path`, `Body`, etc.).

///

## Déclarer les attributs du modèle { #declare-model-attributes }

En déclarant un paramètre de fonction de chemin d'accès de type `Request`, **FastAPI** saura passer la `Request` dans ce paramètre.

/// tip | Astuce

Notez que, dans ce cas, nous déclarons un paramètre de chemin en plus du paramètre de requête.

Ainsi, le paramètre de chemin sera extrait, validé, converti vers le type spécifié et annoté avec OpenAPI.
