## Zusammenfassung { #recap }

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] *}
