# 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

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

//// tab | Python 3.10+

```Python hl_lines="1  3"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py!}
```

            ]
        }
    )

def test_post_files(tmp_path, app: FastAPI):
    path = tmp_path / "test.txt"
    path.write_bytes(b"<file content>")
    path2 = tmp_path / "test2.txt"
    path2.write_bytes(b"<file content2>")

    client = TestClient(app)
    with path.open("rb") as file, path2.open("rb") as file2:
        response = client.post(
            "/files/",
            files=(

# 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。

```

### *path operation関数* の名前をoperationIdとして使用する

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`:

## 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] *}

/// info

        }
        return null;
    }

    // curl -XPOST -H "Authorization: CHANGEME" localhost:8080/api/admin/storage/upload/ -F path=/ -F file=@...
    // POST /api/admin/storage/upload/{pathId}/
    @Execute
    public JsonResponse<ApiResult> post$upload(final UploadForm form) {
        validateApi(form, messages -> {});
        if (form.file == null) {

# 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:

```Python hl_lines="17"

# 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*.

        String[] values;

        values = storageClient.parsePath("bucket/path");
        assertEquals("bucket", values[0]);
        assertEquals("path", values[1]);

        values = storageClient.parsePath("bucket/path1/path2");
        assertEquals("bucket", values[0]);
        assertEquals("path1/path2", values[1]);

        values = storageClient.parsePath("bucket/");
