# Codificador Compatível com JSON { #json-compatible-encoder }

Existem alguns casos em que você pode precisar converter um tipo de dados (como um modelo Pydantic) para algo compatível com JSON (como um `dict`, `list`, etc).

Por exemplo, se você precisar armazená-lo em um banco de dados.

Para isso, **FastAPI** fornece uma função `jsonable_encoder()`.

## Usando a função `jsonable_encoder` { #using-the-jsonable-encoder }

# JSON 相容編碼器 { #json-compatible-encoder }

在某些情況下，你可能需要將某種資料型別（例如 Pydantic 模型）轉換為與 JSON 相容的類型（例如 `dict`、`list` 等）。

例如，當你需要把它儲存在資料庫中。

為此，**FastAPI** 提供了 `jsonable_encoder()` 函式。

## 使用 `jsonable_encoder` { #using-the-jsonable-encoder }

想像你有一個只接受與 JSON 相容資料的資料庫 `fake_db`。

例如，它不接受 `datetime` 物件，因為那與 JSON 不相容。

因此，必須將 `datetime` 物件轉為一個以 [ISO 格式](https://en.wikipedia.org/wiki/ISO_8601) 表示資料的 `str`。

## Metadata for tags { #metadata-for-tags }

You can also add additional metadata for the different tags used to group your path operations with the parameter `openapi_tags`.

It takes a list containing one dictionary for each tag.

Each dictionary can contain:

* `name` (**required**): a `str` with the same tag name you use in the `tags` parameter in your *path operations* and `APIRouter`s.
