Here are several ways to do it.

## Extra JSON Schema data in Pydantic models { #extra-json-schema-data-in-pydantic-models }

You can declare `examples` for a Pydantic model that will be added to the generated JSON Schema.

{* ../../docs_src/schema_extra_example/tutorial001_py310.py hl[13:24] *}

That extra info will be added as-is to the output **JSON Schema** for that model, and it will be used in the API docs.

             the following code:

### 文件中的輸入模型 { #input-model-in-docs }

你可以在文件中確認，`description` 欄位沒有紅色星號，表示不是必填：

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image01.png">
</div>

### 輸出用模型 { #model-for-output }

但如果你把同一個模型用作輸出，如下所示：

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

...由於 `description` 有預設值，就算你沒有為該欄位回傳任何內容，它仍會有那個預設值。

### 輸出回應資料的模型 { #model-for-output-response-data }
