E funcionará e será útil **durante o desenvolvimento**.

Mas se sua conexão com o servidor for perdida, o **processo em execução** provavelmente morrerá.

If you added the return type annotation, tools and editors would complain with a (correct) error telling you that your function is returning a type (e.g. a dict) that is different from what you declared (e.g. a Pydantic model).

Você verá a documentação automática da API, incluindo os caminhos de todos os submódulos, usando os caminhos (e prefixos) corretos e as tags corretas:

## Recap

You can add multiple body parameters to your *path operation function*, even though a request can only have a single body.

But **FastAPI** will handle it, give you the correct data in your function, and validate and document the correct schema in the *path operation*.

You can also declare singular values to be received as part of the body.

	}

	if hnPost.Title != "embedded_pointer_type" {
		t.Errorf("Should find correct value for embedded pointer type")
	}

	if hnPost.Author != nil {
		t.Errorf("Expected to get back a nil Author but got: %v", hnPost.Author)
	}

	now := time.Now().Round(time.Second)
	NewPost := HNPost{
