Instance Method Details

#responders(*responders) ⇒ Object

Adds the given responders to the current controller’s responder, allowing you to cherry-pick which responders you want per controller.

class InvitationsController < ApplicationController
  responders :flash, :http_cache
end

Takes symbols and strings and translates them to VariableResponder (eg. :flash becomes FlashResponder). Also allows passing in the responders modules in directly, so you could do:

responders FlashResponder, HttpCacheResponder

Or a mix of both methods:

responders :flash, MyCustomResponder
