Now for the create code:

  def create
    debug 'create'
    get_parent
    new_resource
    attrs = get_attributes
    if get_resource.update_attributes(attrs) && update_relations && @resource.save
      redirect rest_resource(@parent, @resource)
    else
      # display error messages and reload "new" page
     ...
    end
  end

get_parent sets @parent to nil
get_attributes returns the params['command'] hash
new_resource sets @resource to model.new(get_attributes)
update_relations just returns true because @parent is nil

    # parent is an Array of model instances or nil
    def rest_resource(parent, *args)
      Merb.logger.info "rest_resource(#{parent.inspect}, #{args.inspect})"
      rsrc = nil
      if parent.nil?
        rsrc = resource(*args)
      else
        rsrc = resource(*([parent].flatten + (args || [])))
      end
      Merb.logger.info "rest_resource => #{rsrc}"
      rsrc
    end
