これを使うことで、デフォルト値を省略して、設定された（リクエストで送られた）データのみを含む`dict`を生成することができます:

{* ../../docs_src/body_updates/tutorial002.py hl[34] *}

### Pydanticの`update`パラメータ

ここで、`.copy()`を用いて既存のモデルのコピーを作成し、`update`パラメータに更新するデータを含む`dict`を渡すことができます。

`stored_item_model.copy(update=update_data)`のように:

{* ../../docs_src/body_updates/tutorial002.py hl[35] *}

### 部分的更新のまとめ

まとめると、部分的な更新を適用するには、次のようにします:

func (a adminAPIHandlers) SetRemoteTargetHandler(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()

	vars := mux.Vars(r)
	bucket := pathClean(vars["bucket"])
	update := r.Form.Get("update") == "true"

	// Get current object layer instance.
	objectAPI, _ := validateAdminReq(ctx, w, r, policy.SetBucketTargetAction)
	if objectAPI == nil {
		return
	}

	// Check if bucket exists.
