#### 기본값이 있는 필드를 갖는 값의 데이터

하지만 모델의 필드가 기본값이 있어도 ID가 `bar`인 항목(items)처럼 데이터가 값을 갖는다면:

```Python hl_lines="3  5"
{
    "name": "Bar",

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

参考 <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank">Pydantic 文档</a> 中对 `exclude_defaults` 和 `exclude_none` 的描述。

///

#### 默认值字段有实际值的数据

但是，如果你的数据在具有默认值的模型字段中有实际的值，例如 ID 为 `bar` 的项：

```Python hl_lines="3  5"
{
    "name": "Bar",
    "description": "The bartenders",

* `response_model_exclude_none=True`

как описано в <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank">документации Pydantic</a> для параметров `exclude_defaults` и `exclude_none`.

///

#### Если значение поля отличается от значения по-умолчанию

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

But if your data has values for the model's fields with default values, like the item with ID `bar`:
