        that actually comes up in the real world. We want to hear the real-world use case so the
        community can discuss and debate whether this feature is actually the *best* way to address
        the real use case, or whether or not a different abstraction might be more appropriate.


        It's okay if you can't provide complete context on a use case. We understand if you are not

## Caso de Uso

Empecemos con un ejemplo de **caso de uso** y luego veamos cómo resolverlo con esto.

Imaginemos que tienes algunos **modelos de machine learning** que quieres usar para manejar requests. 🤖

		t.Skipf("This test case skipped, because of only supporting for mysql")
	}

	// case 1: one record, create from map[string]interface{}
	mapValue1 := map[string]interface{}{"name": "create_from_map_with_schema1", "age": 1}

Repare que, neste caso, o `item` que seria capturado a partir do corpo é opcional. Visto que ele possui `None` como valor padrão.

A "bearer" token is not the only option.

But it's the best one for our use case.

And it might be the best for most use cases, unless you are an OAuth2 expert and know exactly why there's another option that better suits your needs.

In that case, **FastAPI** also provides you with the tools to build it.
