You can use the `jsonable_encoder` to convert the input data to data that can be stored as JSON (e.g. with a NoSQL database). For example, converting `datetime` to `str`.

`PUT` is used to receive data that should replace the existing data.

### Warning about replacing { #warning-about-replacing }

Ви можете використати `jsonable_encoder`, щоб перетворити вхідні дані на такі, які можна зберігати як JSON (наприклад, у NoSQL базі даних). Наприклад, перетворюючи `datetime` у `str`.

{* ../../docs_src/body_updates/tutorial001_py310.py hl[28:33] *}

`PUT` використовується для отримання даних, які мають замінити чинні дані.
