If you pass a Mime::Type you must also supply a block. The block will be passed the request raw post data and should return a hash of parsed parameter data

You can also supply a hash of options containing the keys :except or :only to restrict which actions will be parsed

Parameters:

  • mime_type_or_short_cut (Symbol, Mime::Type)
  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):
