그러면 이러한 기본값은 응답에 포함되지 않고, 실제로 설정된 값만 포함됩니다.

따라서 ID가 `foo`인 항목에 대해 해당 *경로 처리*로 요청을 보내면, (기본값을 제외한) 응답은 다음과 같습니다:

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

/// info | 정보

다음도 사용할 수 있습니다:

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

  dependencies:
    locate-path "^5.0.0"
    path-exists "^4.0.0"

flat@^5.0.2:
  version "5.0.2"
  resolved "https://registry.yarnpkg.com/flat/-/flat-5.0.2.tgz#8ca6fe332069ffa9d324c327198c598259ceb241"
  integrity sha512-b6suED+5/3rTpUBdG1gupIl8MPFCAMA0QXwmljLhvCUKcUvdE4gWky9zpuGCcXHOsz4J9wPGNWq6OKpmIzz3hQ==

flatted@^3.2.7:

   * according to this method:
   *
   * 1. Original
   * ```
   * Content-Type: text/html
   * Content-Length: 50
   * ```
   *
   * 2. Different order
   *
   * ```
   * Content-Length: 50
   * Content-Type: text/html
   * ```
   *
   * 3. Different case
   *
   * ```
   * content-type: text/html

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

如此這些預設值就不會被包含在回應中，只有實際被設定的值才會包含。

因此，如果你對該「路徑操作」發送針對 ID 為 `foo` 的項目的請求，回應（不包含預設值）會是：

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

/// info | 說明

你也可以使用：

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

そうすると、デフォルト値はレスポンスに含まれず、実際に設定された値のみが含まれます。

そのため、ID `foo` のitemに対してその *path operation* へリクエストを送ると、レスポンスは以下のようになります（デフォルト値を含まない）:

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

/// info | 情報

以下も使用できます:

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`
