Imagine i have

class Articles < Application

  # params will have :article key here!
  def create(attributes)
    ...
  end
end



# merb-action-args code

  def _call_action(action)
    arguments, defaults = self.class.action_argument_list[action]
    args = arguments.map do |arg, default|
      arg = arg

      # HERE the parameter name must be *right* so that everything works !?!
      # arg will be attributes here, but params doesn't contain it, it contains :article

      p = params.key?(arg.to_sym)
      raise BadRequest unless p || (defaults && defaults.include?(arg))
      p ? params[arg.to_sym] : default
    end
    __send__(action, *args)
  end
