Für ein Beispiel können wir ein `Image`-Modell definieren.

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

### Das Kindmodell als Typ verwenden { #use-the-submodel-as-a-type }

Und dann können wir es als Typ eines Attributes verwenden:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

Das würde bedeuten, dass **FastAPI** einen Body wie folgt erwartet:

```JSON
{

{* ../../docs_src/path_operation_configuration/tutorial004_py310.py hl[17:25] *}

Será usado en la documentación interactiva:

<img src="/img/tutorial/path-operation-configuration/image02.png">

## Descripción del Response { #response-description }

Puedes especificar la descripción del response con el parámetro `response_description`:

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[19] *}

/// info | Información

{* ../../docs_src/path_operation_configuration/tutorial004_py310.py hl[17:25] *}

Ela será usada nas documentações interativas:

<img src="/img/tutorial/path-operation-configuration/image02.png">

## Descrição da resposta { #response-description }

Você pode especificar a descrição da resposta com o parâmetro `response_description`:

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[19] *}

## Atributos con listas de submodelos { #attributes-with-lists-of-submodels }

También puedes usar modelos Pydantic como subtipos de `list`, `set`, etc.:
