.as_json_schema(shallow: false, example: nil, attribute_options: {}) ⇒ Object

Bigdecimal numbers are too big to be represented as numbers in JSON schema The way to do so, is to represent them as strings, but add a ‘format’ specifying how to parse that (seemingly, there is a ‘double’ well known type that json API claims we can use) … not sure if this is the right one, as technically BigDecimal has very large precision that a double wouldn’t be able to fit…
