# Path-параметры и валидация числовых данных

Так же, как с помощью `Query` вы можете добавлять валидацию и метаданные для query-параметров, так и с помощью `Path` вы можете добавлять такую же валидацию и метаданные для path-параметров.

## Импорт Path

Сначала импортируйте `Path` из `fastapi`, а также импортируйте `Annotated`:

### Usando el nombre de la *función de la operación de path* en el operationId

Si quieres usar tus nombres de funciones de API como `operationId`s, puedes iterar sobre todos ellos y sobrescribir `operation_id` de cada *operación de path* usando su `APIRoute.name`.

Deberías hacerlo después de adicionar todas tus *operaciones de path*.
