O benefício de lançar uma exceção em vez de retornar um valor ficará mais evidente na seção sobre Dependências e Segurança.

Neste exemplo, quando o cliente pede, na requisição, por um item cujo ID não existe, a exceção com o status code `404` é lançada:

{* ../../docs_src/handling_errors/tutorial001_py310.py hl[11] *}

### A response resultante { #the-resulting-response }

base de datos dentro de la tarea en segundo plano, y obtendrías los objetos de la base de datos usando esta nueva sesión. Y entonces, en lugar de pasar el objeto de la base de datos como parámetro a la función de la tarea en segundo plano, pasarías el ID de ese objeto y luego obtendrías el objeto de nuevo dentro de la función de la tarea en segundo plano....

innerhalb des Hintergrundtasks eine neue Datenbanksession erstellen und die Objekte aus der Datenbank mithilfe dieser neuen Session beziehen. Und anstatt das Objekt aus der Datenbank als Parameter an die Hintergrundtask-Funktion zu übergeben, würden Sie die ID dieses Objekts übergeben und das Objekt dann innerhalb der Hintergrundtask-Funktion erneut beziehen....

しかし、ID `bar` のitemのように、デフォルト値が設定されているモデルのフィールドに値が設定されている場合:

```Python hl_lines="3  5"
{
    "name": "Bar",
    "description": "The bartenders",
    "price": 62,
    "tax": 20.2
}
```

それらはレスポンスに含まれます。

ID `baz` のitemのようにデフォルト値と同じ値を持つデータの場合:

```Python hl_lines="3  5-6"
