In some cases, it's even possible to have both Pydantic v1 and v2 models in the same **path operation** in your FastAPI app:

{* ../../docs_src/pydantic_v1_in_v2/tutorial003_an_py310.py hl[2:3,6,12,21:22] *}

不必为你使用的所有标签都添加元数据。

///

### 使用你的标签

将 `tags` 参数和*路径操作*（以及 `APIRouter`）一起使用，将其分配给不同的标签：

{* ../../docs_src/metadata/tutorial004.py hl[21,26] *}

/// info | 信息

### 查看文档

如果你现在查看文档，它们会显示所有附加的元数据：

### 标签顺序

每个标签元数据字典的顺序也定义了在文档用户界面显示的顺序。

 * "The .NET Developer's Guide to Windows Security" (which is also
 * available online).
 * <p>
 * Direct ACEs are evaluated first in order. The SID of the user performing
 * the operation and the desired access bits are compared to the SID
 * and access mask of each ACE. If the SID matches, the allow/deny flags
 * and access mask are considered. If the ACE is a "deny"

これらの場合、リストの型宣言を使用して定義することができます。

重複したヘッダーのすべての値をPythonの`list`として受け取ることができます。

例えば、複数回出現する可能性のある`X-Token`のヘッダを定義するには、以下のように書くことができます:

{* ../../docs_src/header_params/tutorial003.py hl[9] *}

もし、その*path operation*で通信する場合は、次のように２つのHTTPヘッダーを送信します:

```
X-Token: foo
X-Token: bar
```

このレスポンスは以下のようになります:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```
