# Separate OpenAPI Schemas for Input and Output or Not

When using **Pydantic v2**, the generated OpenAPI is a bit more exact and **correct** than before. 😎

In fact, in some cases, it will even have **two JSON Schemas** in OpenAPI for the same Pydantic model, for input and output, depending on if they have **default values**.

Let's see how that works and how to change it if you need to do that.

## Pydantic Models for Input and Output

# Esquemas OpenAPI Separados para Entrada e Saída ou Não

Ao usar **Pydantic v2**, o OpenAPI gerado é um pouco mais exato e **correto** do que antes. 😎

Inclusive, em alguns casos, ele terá até **dois JSON Schemas** no OpenAPI para o mesmo modelo Pydantic, para entrada e saída, dependendo se eles possuem **valores padrão**.

Vamos ver como isso funciona e como alterar se for necessário.

the defaults for the Go toolchain used to build the program,
amended to match the Go version listed in `go.mod`,
and then overridden by explicit `//go:debug` lines in the program.

The [GODEBUG History](#history) gives the exact defaults for each Go toolchain version.
For example, Go 1.21 introduces the `panicnil` setting,
controlling whether `panic(nil)` is allowed;
it defaults to `panicnil=0`, making `panic(nil)` a run-time error.

But, sadly, you get nothing useful:

### Add types

Let's modify a single line from the previous version.

We will change exactly this fragment, the parameters of the function, from:

```Python
    first_name, last_name
```

to:

```Python
    first_name: str, last_name: str
```

That's it.

	switch x := sm.MatchType.(type) {
	case *v1alpha3.StringMatch_Exact:
		return x.Exact
	case *v1alpha3.StringMatch_Prefix:

	}

	return sm.String()
}
