Entonces, un objeto `datetime` tendría que ser convertido a un `str` que contenga los datos en formato <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO</a>.

De la misma manera, esta base de datos no recibiría un modelo de Pydantic (un objeto con atributos), solo un `dict`.

Puedes usar `jsonable_encoder` para eso.
