## Liste von Modellen { #list-of-models }

Auf die gleiche Weise können Sie Responses von Listen von Objekten deklarieren.

Dafür verwenden Sie Pythons Standard-`typing.List` (oder nur `list` in Python 3.9 und höher):

/// info | Información

Como verás abajo, esto es muy similar al comportamiento anterior a la versión 0.106.0, pero con varias mejoras y arreglos de bugs para casos límite.

///

#### Casos de uso con salida temprana del código { #use-cases-with-early-exit-code }

        result.set(t.getGenericComponentType());
      }

      @Override
      void visitClass(Class<?> t) {
        result.set(t.getComponentType());
      }
    }.visit(type);
    return result.get();
  }

  /**
   * Returns {@code ? extends X} if any of {@code bounds} is a subtype of {@code X[]}; or null
   * otherwise.
   */

Wenn Sie eine benutzerdefinierte Liste von Servern (`servers`) übergeben und es einen `root_path` gibt (da Ihre API hinter einem Proxy läuft), fügt **FastAPI** einen „Server“ mit diesem `root_path` am Anfang der Liste ein.

Zum Beispiel:

{* ../../docs_src/behind_a_proxy/tutorial003_py39.py hl[4:7] *}

Erzeugt ein OpenAPI-Schema, wie:

/// warning

A `Response` returned directly by your *path operation function* won't be documented in OpenAPI (for example, the `Content-Type` won't be documented) and won't be visible in the automatic interactive docs.

///

/// info

Of course, the actual `Content-Type` header, status code, etc, will come from the `Response` object you returned.

///

           * fails the `ScheduledFuture`, which might be visible only to users who operate directly
           * on the delegate executor's queue.
           *
           * (Users who try to operate directly on the `ScheduledFuture` may have additional
           * problems. For example, if they cancel that `Future`, it won't cancel the user-visible
           * `ListenableScheduledTask`. This is essentially the same problem as the

* Validation de données.
* Annotations d'API et documentation automatique.

Et vous n'avez besoin de le déclarer qu'une fois.

/// warning | Advertencia

Una `Response` devuelta directamente por tu *path operation function* no se documentará en OpenAPI (por ejemplo, el `Content-Type` no se documentará) y no será visible en la documentación interactiva automática.

///

/// info | Información

Por supuesto, el `Content-Type` header real, el código de estado, etc., provendrán del objeto `Response` que devolviste.
