```Python
{"id": id}
```

Mit beispielsweise einer ID `42` würde das wie folgt gerendert werden:

```html
Item ID: 42
```

### Template-`url_for`-Argumente

Sie können `url_for()` auch innerhalb des Templates verwenden, es nimmt als Argumente dieselben Argumente, die von Ihrer *Pfadoperation-Funktion* verwendet werden.

Der Abschnitt mit:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

Você pode configurar alguns <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">parâmetros extras da UI do Swagger</a>.

Para configurá-los, passe o argumento `swagger_ui_parameters` ao criar o objeto de aplicativo `FastAPI()` ou para a função `get_swagger_ui_html()`.

`swagger_ui_parameters` recebe um dicionário com as configurações passadas diretamente para o Swagger UI.

### `Union` en Python 3.10

En este ejemplo pasamos `Union[PlaneItem, CarItem]` como el valor del argumento `response_model`.

Porque lo estamos pasando como un **valor a un argumento** en lugar de ponerlo en una **anotación de tipo**, tenemos que usar `Union` incluso en Python 3.10.

Si estuviera en una anotación de tipo podríamos haber usado la barra vertical, como:

            assertEquals(expectedSize, context.size());
        }

        static Stream<Arguments> provideSizeTestCases() {
            return Stream.of(Arguments.of(0, 0, 4), Arguments.of(1, 0, 6), Arguments.of(0, 1, 5), Arguments.of(1, 1, 7),
                    Arguments.of(5, 10, 24), Arguments.of(10, 20, 44), Arguments.of(20, 32, 76));
        }
    }
