Blank Canvas => 'Отказ отображать документ, потому что отображение запрещено с помощью X-Frame-Options.'

Question

, когда приложение холст загружается в IFrame ничего не дисплей и на Chrome Firebug консоли я вижу ошибку:

Refused to display document because display forbidden by X-Frame-Options.

Я попытался это решение: Overcoming "Display forbidden by X-Frame-Options"

class ApplicationController < ActionController::Base 
protect_from_forgery 
before_filter :set_xframeoption 

def set_xframeoption 
    response.headers["X-Frame-Options"]='GOFORIT' 
end 

end 

Но У меня такая же ошибка. Любое решение?

Благодаря

Если кто-то имеет эту проблему, я установил ее, просто добавив в моей ссылке:

:target => "_top"

Это делает его загружает авторизацию в верхней части окна.
