...entonces el campo `description` **no será requerido**. Porque tiene un valor por defecto de `None`.

### Modelo de Entrada en la Documentación { #input-model-in-docs }

Puedes confirmar eso en la documentación, el campo `description` no tiene un **asterisco rojo**, no está marcado como requerido:

<div class="screenshot">

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

... então o campo `description` **não será obrigatório**. Porque ele tem um valor padrão de `None`.

### Modelo de Entrada na Documentação { #input-model-in-docs }

Você pode confirmar que na documentação, o campo `description` não tem um **asterisco vermelho**, não é marcado como obrigatório:

<div class="screenshot">

    [
        ("/items/foo", {"name": "Foo", "price": 50.2}),
        (
            "/items/bar",
            {"name": "Bar", "description": "The bartenders", "price": 62, "tax": 20.2},
        ),

                "tax": 10.5,

            },
        ),

class Item(BaseModel):
    name: str
    description: str | None = None
    price: float
    tax: float = 10.5


items = {
    "foo": {"name": "Foo", "price": 50.2},
    "bar": {"name": "Bar", "description": "The Bar fighters", "price": 62, "tax": 20.2},
    "baz": {
        "name": "Baz",
        "description": "There goes my baz",
        "price": 50.2,
        "tax": 10.5,
    },
}

## Summary and description { #summary-and-description }

You can add a `summary` and `description`:

{* ../../docs_src/path_operation_configuration/tutorial003_py310.py hl[18:19] *}

## Description from docstring { #description-from-docstring }

    assert response.json() == {"name": "Foo", "description": None}


def test_read_items(client: TestClient) -> None:
    response = client.get("/items/")
    assert response.status_code == 200, response.text
    assert response.json() == [
        {
            "name": "Portal Gun",
            "description": "Device to travel through the multi-rick-verse",
        },

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

...then the `description` field will **not be required**. Because it has a default value of `None`.

### Input Model in Docs { #input-model-in-docs }

You can confirm that in the docs, the `description` field doesn't have a **red asterisk**, it's not marked as required:
