## Campos de lista { #list-fields }

Puedes definir un atributo como un subtipo. Por ejemplo, una `list` en Python:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Esto hará que `tags` sea una lista, aunque no declare el tipo de los elementos de la lista.

## Prohibir Campos de Formulario Extra { #forbid-extra-form-fields }

En algunos casos de uso especiales (probablemente no muy comunes), podrías querer **restringir** los campos de formulario a solo aquellos declarados en el modelo de Pydantic. Y **prohibir** cualquier campo **extra**.

    Check that custom middlewares don't affect the contextvar context for dependencies.

    The code before yield and the code after yield should be run in the same contextvar

Das Erste, was auffällt, ist, dass wir eine asynchrone Funktion mit `yield` definieren. Das ist sehr ähnlich zu Abhängigkeiten mit `yield`.

{* ../../docs_src/events/tutorial003_py39.py hl[14:19] *}

Der erste Teil der Funktion, vor dem `yield`, wird ausgeführt **bevor** die Anwendung startet.

Und der Teil nach `yield` wird ausgeführt, **nachdem** die Anwendung beendet ist.
