That documents (and validates, serializes, filters) the output data, as a `list` of `Note`s.

## Create notes

Create the *path operation function* to create notes:

```Python hl_lines="61-65"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

!!! info
    In Pydantic v1 the method was called `.dict()`, it was deprecated (but still supported) in Pydantic v2, and renamed to `.model_dump()`.

下面，我们逐步说明修改的代码内容。

## OAuth2 安全方案

第一个修改的地方是，使用两个作用域 `me` 和 `items ` 声明 OAuth2 安全方案。

`scopes` 参数接收**字典**，键是作用域、值是作用域的描述：

```Python hl_lines="62-65"
{!../../../docs_src/security/tutorial005.py!}
```

因为声明了作用域，所以登录或授权时会在 API 文档中显示。

此处，选择给予访问权限的作用域： `me` 和 `items`。

这也是使用脸书、谷歌、GitHub 登录时的授权机制。
