## Using the `jsonable_encoder`

Let's imagine that you have a database `fake_db` that only receives JSON compatible data.

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

So, a `datetime` object would have to be converted to a `str` containing the data in <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO format</a>.

## Использование `jsonable_encoder`

Представим, что у вас есть база данных `fake_db`, которая принимает только JSON-совместимые данные.

Например, он не принимает объекты `datetime`, так как они не совместимы с JSON.

В таком случае объект `datetime` следует преобразовать в строку соответствующую <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">формату ISO</a>.

## Usando a função `jsonable_encoder`

Vamos imaginar que você tenha um banco de dados `fake_db` que recebe apenas dados compatíveis com JSON.

Por exemplo, ele não recebe objetos `datetime`, pois estes objetos não são compatíveis com JSON.

Então, um objeto `datetime` teria que ser convertido em um `str` contendo os dados no formato  <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO</a>.
