1. Мы по-прежнему импортируем `field` из стандартных `dataclasses`.

2. `pydantic.dataclasses` — полностью совместимая замена (drop-in replacement) для `dataclasses`.

3. Dataclass `Author` содержит список dataclass `Item`.

4. Dataclass `Author` используется в параметре `response_model`.

5. Вы можете использовать и другие стандартные аннотации типов вместе с dataclasses в качестве тела запроса.

2. `pydantic.dataclasses` 是 `dataclasses` 的可直接替換版本。
3. `Author` dataclass 內含一個 `Item` dataclass 的清單。
4. `Author` dataclass 被用作 `response_model` 參數。
5. 你可以將其他標準型別註記與 dataclass 一起用作請求本文。

   在此例中，它是 `Item` dataclass 的清單。
6. 這裡我們回傳一個字典，其中的 `items` 是一個 dataclass 清單。

   FastAPI 仍能將資料<dfn title="將資料轉換成可傳輸的格式">序列化</dfn>為 JSON。
7. 這裡 `response_model` 使用的是「`Author` dataclass 的清單」這種型別註記。

   同樣地，你可以把 `dataclasses` 與標準型別註記組合使用。
