## Use cases { #use-cases }

Some use cases include:

* Converting non-JSON request bodies to JSON (e.g. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.

## Handling custom request body encodings { #handling-custom-request-body-encodings }

     * Determines if the parent is part of the same reactor (multi-module project)
     * vs. an external parent POM by checking if the parent exists in the pomMap.
     */
    private boolean isParentInReactor(Element parentElement, Map<Path, Document> pomMap, UpgradeContext context) {
        // If relativePath is explicitly set to empty, parent is definitely external
        String relativePath = parentElement.childText(MavenPomElements.Elements.RELATIVE_PATH);

For example, let's add <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">ReDoc's OpenAPI extension to include a custom logo</a>.

### Normal **FastAPI** { #normal-fastapi }

First, write all your **FastAPI** application as normally:

To distinguish from the models with all optional values for **updates** and models with required values for **creation**, you can use the ideas described in [Extra Models](extra-models.md){.internal-link target=_blank}.

# Тіло – Оновлення

## Оновлення з використанням `PUT`

Щоб оновити елемент, Ви можете використати <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a> операцію.

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`.
