If you want to receive partial updates, it's very useful to use the parameter `exclude_unset` in Pydantic's model's `.model_dump()`.

Like `item.model_dump(exclude_unset=True)`.

That would generate a `dict` with only the data that was set when creating the `item` model, excluding default values.

Then you can use this to generate a `dict` with only the data that was set (sent in the request), omitting default values:

### 動作確認 { #check-it }

ブラウザで [http://127.0.0.1:8000/items/5?q=somequery](http://127.0.0.1:8000/items/5?q=somequery) を開きます。

以下の JSON のレスポンスが確認できます。

```JSON
{"item_id": 5, "q": "somequery"}
```

すでに以下の API が作成されています。

* _パス_ `/` と `/items/{item_id}` で HTTP リクエストを受け取ります。
* 両方の _パス_ は `GET` 操作（HTTP _メソッド_ としても知られています）を取ります。
* _パス_ `/items/{item_id}` は `int` であるべき _パスパラメータ_ `item_id` を持ちます。
