예를 들면, 위의 이 모델은 JSON "`object`" (혹은 파이썬 `dict`)을 다음과 같이 선언합니다:

```JSON
{
    "name": "Foo",
    "description": "선택적인 설명란",
    "price": 45.2,
    "tax": 3.5
}
```

...`description`과 `tax`는 (기본 값이 `None`으로 되어 있어) 선택적이기 때문에, 이 JSON "`object`"는 다음과 같은 상황에서도 유효합니다:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

## 매개변수로서 선언하기

    public void testValueExtractorWithAInvalidExpression() throws Exception {
        assertNull(ReflectionValueExtractor.evaluate("project.foo", project));
        assertNull(ReflectionValueExtractor.evaluate("project.dependencies[10]", project));
        assertNull(ReflectionValueExtractor.evaluate("project.dependencies[0].foo", project));
    }

    /**
     * <p>testMappedDottedKey.</p>

你可以设置*路径操作装饰器*的 `response_model_exclude_unset=True` 参数：

```Python hl_lines="24"
{!../../docs_src/response_model/tutorial004.py!}
```

然后响应中将不会包含那些默认值，而是仅有实际设置的值。

因此，如果你向*路径操作*发送 ID 为 `foo` 的商品的请求，则响应（不包括默认值）将为：

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```
