request_body_to_args

Converts a received request body into a dictionary of validated arguments and a list of validation errors based on the provided model fields. It handles form data extraction, embedded field logic, and validates each field against its corresponding model definition.

def request_body_to_args(
    body_fields: list[ModelField],
    received_body: dict[str, Any] | FormData | bytes | None,
    embed_body_fields: bool
) - > tuple[dict[str, Any], list[dict[str, Any]]]

Maps and validates raw request body data into a dictionary of arguments based on defined model fields. This function handles the extraction logic for both single-field and multi-field bodies, including special processing for form data and embedded field configurations.
