Burada `Query()` kullanıyoruz çünkü bu bir **query parametresi**. İleride `Path()`, `Body()`, `Header()` ve `Cookie()` gibi, `Query()` ile aynı argümanları kabul eden diğerlerini de göreceğiz.

上の例では、入力モデルは Pydantic v1、出力モデル（`response_model=ItemV2` で定義）は Pydantic v2 です。

### Pydantic v1 のパラメータ { #pydantic-v1-parameters }

Pydantic v1 のモデルで `Body`、`Query`、`Form` などの FastAPI 固有のパラメータユーティリティを使う必要がある場合、v2 への移行が完了するまでの間は `fastapi.temp_pydantic_v1_params` からインポートできます:

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

### 段階的に移行 { #migrate-in-steps }

### Paramètres Pydantic v1 { #pydantic-v1-parameters }

Si vous devez utiliser certains des outils spécifiques à FastAPI pour les paramètres comme `Body`, `Query`, `Form`, etc., avec des modèles Pydantic v1, vous pouvez les importer depuis `fastapi.temp_pydantic_v1_params` le temps de terminer la migration vers Pydantic v2 :

在上面的示例中，输入模型是 Pydantic v1 模型，输出模型（在 `response_model=ItemV2` 中定义）是 Pydantic v2 模型。

### Pydantic v1 参数 { #pydantic-v1-parameters }

如果你需要在 Pydantic v1 模型中使用 FastAPI 特有的参数工具，如 `Body`、`Query`、`Form` 等，在完成向 Pydantic v2 的迁移前，可以从 `fastapi.temp_pydantic_v1_params` 导入它们：

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

### 分步迁移 { #migrate-in-steps }
