# Path Parameters and Numeric Validations { #path-parameters-and-numeric-validations }

In the same way that you can declare more validations and metadata for query parameters with `Query`, you can declare the same type of validations and metadata for path parameters with `Path`.

## Import Path { #import-path }

First, import `Path` from `fastapi`, and import `Annotated`:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

Do mesmo modo que você pode declarar mais validações e metadados para parâmetros de consulta com `Query`, você pode declarar os mesmos tipos de validações e metadados para parâmetros de rota com `Path`.

## Importe `Path`

Primeiro, importe `Path` de `fastapi`:

{* ../../docs_src/path_params_numeric_validations/tutorial001_py310.py hl[1] *}

## Declare metadados

Você pode declarar todos os parâmetros da mesma maneira que na `Query`.

## Importer Path

Tout d'abord, importez `Path` de `fastapi`, et importez `Annotated` :

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

# Path Operationの高度な設定

## OpenAPI operationId

/// warning | 注意

あなたがOpenAPIの「エキスパート」でなければ、これは必要ないかもしれません。

///

*path operation* で `operation_id` パラメータを利用することで、OpenAPIの `operationId` を設定できます。

`operation_id` は各オペレーションで一意にする必要があります。

# Dependencies in path operation decorators { #dependencies-in-path-operation-decorators }

In some cases you don't really need the return value of a dependency inside your *path operation function*.

Or the dependency doesn't return a value.

But you still need it to be executed/solved.

For those cases, instead of declaring a *path operation function* parameter with `Depends`, you can add a `list` of `dependencies` to the *path operation decorator*.

# Dependencias en decoradores de *path operation*

En algunos casos realmente no necesitas el valor de retorno de una dependencia dentro de tu *path operation function*.

O la dependencia no devuelve un valor.

Pero aún necesitas que sea ejecutada/resuelta.

Para esos casos, en lugar de declarar un parámetro de *path operation function* con `Depends`, puedes añadir una `list` de `dependencies` al decorador de *path operation*.

# path operationデコレータの依存関係

場合によっては*path operation関数*の中で依存関係の戻り値を本当に必要としないこともあります。

もしくは、依存関係が値を返さない場合もあります。

しかし、それでも実行・解決する必要があります。

このような場合、*path operation関数*のパラメータを`Depends`で宣言する代わりに、*path operation decorator*に`dependencies`の`list`を追加することができます。

##  *path operationデコレータ*への`dependencies`の追加

*path operationデコレータ*はオプショナルの引数`dependencies`を受け取ります。

それは`Depends()`の`list`であるべきです:

{* ../../docs_src/dependencies/tutorial006.py hl[17] *}
