#### 別のモデルの内容からつくるPydanticモデル { #a-pydantic-model-from-the-contents-of-another }

上述の例では`user_in.model_dump()`から`user_dict`をこのコードのように取得していますが:

```Python
user_dict = user_in.model_dump()
UserInDB(**user_dict)
```

これは以下と同等です:

戻り値の型を省略することもできます。FastAPI は [`jsonable_encoder`](./encoder.md) を使ってデータを変換し、送信します。

## `ServerSentEvent` { #serversentevent }

`event`、`id`、`retry`、`comment` などの SSE フィールドを設定する必要がある場合は、生データの代わりに `ServerSentEvent` オブジェクトを `yield` できます。

`ServerSentEvent` は `fastapi.sse` からインポートします:

It is an error if the constant value
cannot be <a href="#Representability">represented</a> as a value of the respective type.
If the type is a type parameter, the constant is converted into a non-constant
value of the type parameter.

An untyped constant has a <i>default type</i> which is the type to which the
constant is implicitly converted in contexts where a typed value is required,
