# JSON Compatible Encoder

Існують випадки, коли вам може знадобитися перетворити тип даних (наприклад, модель Pydantic) в щось сумісне з JSON (наприклад, `dict`, `list`, і т. д.).

Наприклад, якщо вам потрібно зберегти це в базі даних.

Для цього, **FastAPI** надає `jsonable_encoder()` функцію.

## Використання `jsonable_encoder`

Давайте уявимо, що у вас є база даних `fake_db`, яка приймає лише дані, сумісні з JSON.

...o prefixo não deve incluir um `/` final.

Então, o prefixo neste caso é `/items`.

Também podemos adicionar uma lista de `tags` e `responses` extras que serão aplicadas a todas as *operações de rota* incluídas neste roteador.

E podemos adicionar uma lista de `dependencies` que serão adicionadas a todas as *operações de rota* no roteador e serão executadas/resolvidas para cada solicitação feita a elas.
