Primero, tienes que importarlo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

/// warning | Advertencia

Fíjate que `Field` se importa directamente desde `pydantic`, no desde `fastapi` como el resto (`Query`, `Path`, `Body`, etc).

///

## Declarar atributos del modelo

Después puedes utilizar `Field` con los atributos del modelo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}
