## Highlights

- Supports source and destination buckets to have the same name unlike AWS S3, addresses variety of use-cases such as *Splunk*, *Veeam* site to site DR.
- Supports object locking/retention across source and destination buckets natively out of the box, unlike AWS S3.

這表示你可以安裝最新的 Pydantic v2，並從該子模組匯入並使用舊的 Pydantic v1 元件，就像安裝了舊版 Pydantic v1 一樣。

{* ../../docs_src/pydantic_v1_in_v2/tutorial001_an_py310.py hl[1,4] *}

### FastAPI 對 v2 中 Pydantic v1 的支援 { #fastapi-support-for-pydantic-v1-in-v2 }

自 FastAPI 0.119.0 起，也支援透過 Pydantic v2 內的 Pydantic v1（部分）以協助遷移至 v2。

因此，你可以先升級到最新的 Pydantic v2，並將匯入改為使用 `pydantic.v1` 子模組，在多數情況下即可正常運作。

/**
 * This class provides a skeletal implementation of the {@code Iterator} interface, to make this

ただし、dotenv ファイルは必ずしもその正確なファイル名である必要はありません。

Pydantic は外部ライブラリを使ってこの種のファイルからの読み込みをサポートしています。詳細は [Pydantic Settings: Dotenv (.env) support](https://docs.pydantic.dev/latest/concepts/pydantic_settings/#dotenv-env-support) を参照してください。

/// tip | 豆知識

これを機能させるには、`pip install python-dotenv` が必要です。

### `.env` ファイル { #the-env-file }

次のような `.env` ファイルを用意できます:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

But then we get a `dict` in the parameter `commons` of the *path operation function*.

And we know that editors can't provide a lot of support (like completion) for `dict`s, because they can't know their keys and value types.

We can do better...

Up to now you have seen dependencies declared as functions.
