Flask est un "micro-framework", il ne comprend pas d'intégrations de bases de données ni beaucoup de choses qui sont fournies par défaut dans Django.

Cette simplicité et cette flexibilité permettent d'utiliser des bases de données NoSQL comme principal système de stockage de données.

Gardez cela à l'esprit lorsque vous lisez "serveur" en général, cela pourrait faire référence à l'une de ces deux choses.

Usará el código de estado por defecto o el que configures en tu *path operation*.

Você também pode declarar um corpo como um `dict` com chaves de algum tipo e valores de outro tipo.

Sem ter que saber de antemão quais são os nomes de campos/atributos válidos (como seria o caso dos modelos Pydantic).

Isso seria útil se você deseja receber chaves que ainda não conhece.

---

Outro caso útil é quando você deseja ter chaves de outro tipo, por exemplo, `int`.

É isso que vamos ver aqui.
