@content_for_layout は非推奨
Even the old @content_for_layout in the layout is deprecated in favor of just using yield in its place.
Use params, not @params
class ApplicationController < ActionController::Base
protect_from_forgery
before_filter :authenticate
private
def authenticate
redirect_to url_for :controller => "welcome" unless session[:login]
end
end
