## Modelos Anidados { #nested-models }

Cada atributo de un modelo Pydantic tiene un tipo.

Pero ese tipo puede ser en sí mismo otro modelo Pydantic.

Así que, puedes declarar "objetos" JSON anidados profundamente con nombres de atributos específicos, tipos y validaciones.

Todo eso, de manera arbitraria.

### Definir un submodelo { #define-a-submodel }

Por ejemplo, podemos definir un modelo `Image`:

En este caso, **FastAPI** notará que hay más de un parámetro del cuerpo en la función (hay dos parámetros que son modelos de Pydantic).

Entonces, usará los nombres de los parámetros como claves (nombres de campo) en el cuerpo, y esperará un cuerpo como:

```JSON
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    },

    assertThat(cacheControl.minFreshSeconds).isEqualTo(3)
    assertThat(cacheControl.onlyIfCached).isTrue()
    assertThat(cacheControl.noTransform).isTrue()
    assertThat(cacheControl.immutable).isTrue()

    // These members are accessible to response headers only.
    assertThat(cacheControl.sMaxAgeSeconds).isEqualTo(-1)
    assertThat(cacheControl.isPrivate).isFalse()
    assertThat(cacheControl.isPublic).isFalse()

4. **Before Submitting**:
   - Run `make verify` to check formatting, linting, and tests.
   - Reference related issues (e.g., “Closes #1234”).
   - Notify team members via GitHub `@mentions` if urgent or complex.

## Reviewing PRs

Reviewers ensure MinIO’s commit history remains a clear, reliable record. Responsibilities include:

1. **Commit Quality**:

/// note | Detalhes Técnicos

`Header` é uma classe "irmã" de `Path`, `Query` e `Cookie`. Ela também herda da mesma classe em comum `Param`.

Mas lembre-se que quando você importa `Query`, `Path`, `Header`, e outras de `fastapi`, elas são na verdade funções que retornam classes especiais.
