### Model for Output { #model-for-output }

But if you use the same model as an output, like here:

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

...then because `description` has a default value, if you **don't return anything** for that field, it will still have that **default value**.

### Model for Output Response Data { #model-for-output-response-data }

        CharMappingItem item3 = new CharMappingItem(3L, inputs1, "output");

        // Two items with same inputs and null output should be equal
        assertTrue(item1.equals(item2));

        // Item with null output should not equal item with non-null output
        assertFalse(item3.equals(item1));
        assertFalse(item1.equals(item3));

        // Item with null output should not equal item with different inputs

### 文件中的輸出模型 { #model-for-output-in-docs }

你也可以在文件中檢視輸出模型，`name` 與 `description` 都以紅色星號標示為必填：

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

### 文件中的輸入與輸出模型 { #model-for-input-and-output-in-docs }

如果你查看 OpenAPI 中所有可用的結構描述（JSON Schema），會看到有兩個：`Item-Input` 與 `Item-Output`。

對於 `Item-Input`，`description` 不是必填，沒有紅色星號。

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

你也可以在文档中查看输出模型，`name` 和 `description` **都**被**红色星号**标记为**必填**：

<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。
