## Daten-<abbr title="Auch bekannt als: Serialisierung, Parsen, Marshalling">Konversion</abbr>

Wenn Sie dieses Beispiel ausführen und Ihren Browser unter <a href="http://127.0.0.1:8000/items/3" class="external-link" target="_blank">http://127.0.0.1:8000/items/3</a> öffnen, sehen Sie als Response:

```JSON

            return true;
        }

        // Check for identity or widening reference conversion
        if (actual != null && formal.isAssignableFrom(actual)) {
            return true;
        }

        // Check for boxing with widening primitive conversion. Note that
        // actual parameters are never primitives.
        if (formal.isPrimitive()) {

/// tip

`JSONResponse` itself is a sub-class of `Response`.

///

And when you return a `Response`, **FastAPI** will pass it directly.

It won't do any data conversion with Pydantic models, it won't convert the contents to any type, etc.

This gives you a lot of flexibility. You can return any data type, override any data declaration or validation, etc.

* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

## Other data types

Here are some of the additional data types you can use:

* `UUID`:

        String version = model.getVersion();
        String modVersion = replaceCiFriendlyVersion(context, version);
        model.setVersion(modVersion);

        Parent parent = model.getParent();
        if (parent != null) {
            version = parent.getVersion();
            modVersion = replaceCiFriendlyVersion(context, version);
            parent.setVersion(modVersion);
        }
    }

    //

<h3 id="Conversions">Conversions</h3>

<p>
A conversion changes the <a href="#Types">type</a> of an expression
to the type specified by the conversion.
A conversion may appear literally in the source, or it may be <i>implied</i>
by the context in which an expression appears.
</p>

<p>
An <i>explicit</i> conversion is an expression of the form <code>T(x)</code>

        "name": "The Foo live"
    }
}
```

Again, doing just that declaration, with **FastAPI** you get:

* Editor support (completion, etc.), even for nested models
* Data conversion
* Data validation
* Automatic documentation

## Special types and validation

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.

/// tip | Consejo

`JSONResponse` en sí misma es una subclase de `Response`.

///

Y cuando devuelves una `Response`, **FastAPI** la pasará directamente.

No hará ninguna conversión de datos con modelos Pydantic, no convertirá el contenido a ningún tipo, etc.

Esto te da mucha flexibilidad. Puedes devolver cualquier tipo de dato, sobrescribir cualquier declaración de datos o validación, etc.

/// note | "Remarque"

`JSONResponse` est elle-même une sous-classe de `Response`.

///

Et quand vous retournez une `Response`, **FastAPI** la transmet directement.

Elle ne fera aucune conversion de données avec les modèles Pydantic, elle ne convertira pas le contenu en un type quelconque.
