自從 Pydantic v2 發佈後，生成的 OpenAPI 比以往更精確也更正確。😎

實際上，在某些情況下，同一個 Pydantic 模型在 OpenAPI 中會同時有兩個 JSON Schema：分別用於輸入與輸出，這取決於它是否有預設值。

來看看它如何運作，以及若需要時該如何調整。

## 作為輸入與輸出的 Pydantic 模型 { #pydantic-models-for-input-and-output }

假設你有一個帶有預設值的 Pydantic 模型，如下所示：

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### 輸入用模型 { #model-for-input }

如果你把這個模型用作輸入，如下所示：

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image03.png">
</div>

### 文档中的输入/输出模型 { #model-for-input-and-output-in-docs }

如果你查看 OpenAPI 中可用的所有 Schema（JSON Schema），你会看到有两个，一个是 `Item-Input`，一个是 `Item-Output`。

对于 `Item-Input`，`description` **不是必填**，没有红色星号。

但对于 `Item-Output`，`description` 是**必填**，带有红色星号。

### 문서에서의 입력과 출력 모델 { #model-for-input-and-output-in-docs }

또 OpenAPI에서 사용 가능한 모든 Schemas(JSON Schemas)를 확인해 보면, `Item-Input` 하나와 `Item-Output` 하나, 이렇게 두 개가 있는 것을 볼 수 있습니다.

`Item-Input`에서는 `description`이 **필수가 아니며**, 빨간 별표가 없습니다.

하지만 `Item-Output`에서는 `description`이 **필수이며**, 빨간 별표가 있습니다.
