It will all be combined and included in your OpenAPI, and shown in the API docs:

<img src="/img/tutorial/additional-responses/image01.png">

## Combine predefined responses and custom ones { #combine-predefined-responses-and-custom-ones }

You might want to have some predefined responses that apply to many *path operations*, but you want to combine them with custom responses needed by each *path operation*.

{* ../../docs_src/path_params/tutorial003b.py hl[6,11] *}

The first one will always be used since the path matches first.

## Predefined values { #predefined-values }

If you have a *path operation* that receives a *path parameter*, but you want the possible valid *path parameter* values to be predefined, you can use a standard Python <abbr title="Enumeration">`Enum`</abbr>.

### Create an `Enum` class { #create-an-enum-class }

{* ../../docs_src/path_params/tutorial003b.py hl[6,11] *}

La primera siempre será utilizada ya que el path coincide primero.

## Valores predefinidos

Si tienes una *path operation* que recibe un *path parameter*, pero quieres que los valores posibles válidos del *path parameter* estén predefinidos, puedes usar un <abbr title="Enumeration">`Enum`</abbr> estándar de Python.

### Crear una clase `Enum`

* `skip`, un `int` con un valor por defecto de `0`.
* `limit`, un `int` opcional.

/// tip | Consejo

También podrías usar `Enum`s de la misma manera que con [Parámetros de Path](path-params.md#predefined-values){.internal-link target=_blank}.

* `skip`, `int` зі значенням за замовчуванням `0`.
* `limit`, опціональний `int`.


/// tip | Підказка

Ви також можете використовувати `Enum`-и, так само як і з [Path Parameters](path-params.md#predefined-values){.internal-link target=_blank}.

* `needy`, a required `str`.
* `skip`, an `int` with a default value of `0`.
* `limit`, an optional `int`.

/// tip

You could also use `Enum`s the same way as with [Path Parameters](path-params.md#predefined-values){.internal-link target=_blank}.

///

## Deployment Concepts { #deployment-concepts }

These examples run the server program (e.g Uvicorn), starting **a single process**, listening on all the IPs (`0.0.0.0`) on a predefined port (e.g. `80`).

This is the basic idea. But you will probably want to take care of some additional things, like:

* Security - HTTPS
* Running on startup
* Restarts

        assertFalse(SmbOperationException.ErrorCode.UNKNOWN_ERROR.isRetryable());
        assertFalse(SmbOperationException.ErrorCode.INTERNAL_ERROR.isRetryable());
    }

    @Test
    @DisplayName("Should test predefined retry policies")
    void testPredefinedRetryPolicies() {
        // DEFAULT policy
        SmbOperationException.RetryPolicy defaultPolicy = SmbOperationException.RetryPolicy.DEFAULT;

Para simplificar, aquí solo estamos añadiendo los scopes recibidos directamente al token.

Pero en tu aplicación, por seguridad, deberías asegurarte de añadir solo los scopes que el usuario realmente puede tener, o los que has predefinido.

{* ../../docs_src/security/tutorial005_an_py310.py hl[156] *}

## Declarar scopes en *path operations* y dependencias

For simplicity, here we are just adding the scopes received directly to the token.

But in your application, for security, you should make sure you only add the scopes that the user is actually able to have, or the ones you have predefined.

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[157] *}
