Beware: Don't name a controller action "cookies"

The method cookies is defined in the ActionController and should never be overwritten.

Bad example

class StaticPagesController < ApplicationController def imprint end def cookies redirect_to '/' end end

If you create an action called cookies, any call to the cookie storage will be broken and call the method. What's more, in this example calls to static_pages_controller#imprint might as well end up redirecting to the homepage.


Just define the action as cookies_action or similar and adjust your route, i.e.:

get :cookies, to: 'footer_pages#cookies_action'
