# ボディ - 更新

## `PUT`による置換での更新

項目を更新するには<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTPの`PUT`</a>操作を使用することができます。

`jsonable_encoder`を用いて、入力データをJSON形式で保存できるデータに変換することができます（例：NoSQLデータベース）。例えば、`datetime`を`str`に変換します。

```Python hl_lines="30 31 32 33 34 35"
{!../../docs_src/body_updates/tutorial001.py!}
```

既存のデータを置き換えるべきデータを受け取るために`PUT`は使用されます。

### 置換についての注意

   * <p><b>Note:</b> this method is now unnecessary and should be treated as deprecated. Instead,
   * use the {@code ArrayList} {@linkplain ArrayList#ArrayList() constructor} directly, taking
   * advantage of <a
   * href="https://docs.oracle.com/javase/tutorial/java/generics/genTypeInference.html#type-inference-instantiation">"diamond"
   * syntax</a>.
