500.html以外を表示したい場合。

# /lib/exceptions.rb
module Exceptions
  class PaymentGatewayError < StandardError; end
end

# /app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  rescue_from Exceptions::PaymentGatewayError do |exception|
    render(:file => "#{Rails.root}/public/payment_error", :layout => false, :status => 500)
  end
end

# /public/payment_error.html
<html><body>決済エラー</body></html>

これでraise Exceptions::PaymentGatewayErrorとかってやるとpayment_error.htmlが表示される。
