### Usar el nombre de la *path operation function* como el operationId { #using-the-path-operation-function-name-as-the-operationid }

Si quieres usar los nombres de las funciones de tus APIs como `operationId`s, puedes iterar sobre todas ellas y sobrescribir el `operation_id` de cada *path operation* usando su `APIRoute.name`.

Deberías hacerlo después de agregar todas tus *path operations*.

# 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] *}

# 路径参数和数值校验

与使用 `Query` 为查询参数声明更多的校验和元数据的方式相同，你也可以使用 `Path` 为路径参数声明相同类型的校验和元数据。

## 导入 Path

首先，从 `fastapi` 导入 `Path`：

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

## 声明元数据

你可以声明与 `Query` 相同的所有参数。

例如，要声明路径参数 `item_id`的 `title` 元数据值，你可以输入：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note

路径参数总是必需的，因为它必须是路径的一部分。

# 경로 매개변수와 숫자 검증

`Query`를 사용하여 쿼리 매개변수에 더 많은 검증과 메타데이터를 선언하는 방법과 동일하게 `Path`를 사용하여 경로 매개변수에 검증과 메타데이터를 같은 타입으로 선언할 수 있습니다.

## 경로 임포트

먼저 `fastapi`에서 `Path`를 임포트합니다:

{* ../../docs_src/path_params_numeric_validations/tutorial001.py hl[3] *}

## 메타데이터 선언

`Query`에 동일한 매개변수를 선언할 수 있습니다.

예를 들어, `title` 메타데이터 값을 경로 매개변수 `item_id`에 선언하려면 다음과 같이 입력할 수 있습니다:

{* ../../docs_src/path_params_numeric_validations/tutorial001.py hl[10] *}

# 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。

{* ../../docs_src/path_operation_advanced_configuration/tutorial001.py hl[6] *}

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