前述のとおり、Python の最近のバージョン（Python 3.14 以降）では Pydantic v1 がサポートされないため、`pydantic.v1` の使用も Python 3.14 以上ではサポートされません。

### 同一アプリでの Pydantic v1 と v2 { #pydantic-v1-and-v2-on-the-same-app }

Pydantic v2 のモデルのフィールドに Pydantic v1 のモデルを（またはその逆を）埋め込むことは、Pydantic では「サポートされていません」。

依存関係の1つが同じ*path operation*に対して複数回宣言されている場合、例えば、複数の依存関係が共通のサブ依存関係を持っている場合、**FastAPI** はリクエストごとに1回だけそのサブ依存関係を呼び出します。
