If you implement the methods PUT, POST and/or PATCH,
you must implement the `content_types_accepted` callback,
and one `AcceptResource` callback for each content-type
it returns. Prefix the `AcceptResource` callback names
and one `AcceptCallback` callback for each content-type
it returns. Prefix the `AcceptCallback` callback names
with `from_` for clarity. For example, `from_html` or
`from_json`.
