Heroku Website stürzt ab mit Rails 3.2.9 und Route Constraint

Question

Meine Website, gehostet in Heroku, funktioniert gut mit Rails 3.2.8. Ich verwende eine Route Constraint-Klasse mit dem Hochspannungs- Juwel für statische (meist) Webseiten: routes.rb:

get "/*id" => "high_voltage/pages#show", constraints: Constraints::StaticPage.new 

Ich habe eine Datei in /lib/constraints/static_page.rb:

module Constraints 
    class StaticPage 
    def matches?(request) 
     File.exist? file_path(request.path) 
    end 

    private 

    def file_path(view) 
     static_page_views_dir.to_s.concat("#{view}.html.erb") 
    end 

    def static_page_views_dir 
     Rails.root.join('app', 'views', 'pages') 
    end 
    end 
end 

Problem ist, ich habe gerade aktualisiert 3.2.9 Rails und hat einen git push heroku und meine App abgestürzt :(

my-host:my-site scott$ heroku ps 
=== web: `bundle exec rails server -p $PORT` 
web.1: crashed 2012/11/14 12:14:41 (~ 2s ago) 

Offenbar Rubin/Heroku kann nicht meine Constraints::StaticPage Klasse finden. Ich habe es require d an der Spitze meiner routes.rb:

require 'constraints/static_page' 

Hat sich etwas ändern in Rails 3.2.9, so dass nicht mehr funktioniert mit Heroku? Lokal funktioniert alles gut, nur nicht in Heroku. Wenn ich diese Beschränkung in meiner Route herausnehme, funktioniert alles perfekt (abgesehen davon, dass ich diese Einschränkungen nicht habe). Hier ist meine heroku logs Ausgabe:

Answer 1

Können Sie die folgenden Versionen in Ihrem Gemfile ausprobieren:

# Gemfile 
gem 'rails', '3.2.9' 
gem 'high_voltage', '~> 1.2.1' 
gem 'thin' 

# ... 

Die 1.2.1 Freisetzung von High Voltage hat die Wurzel Route Einschränkungen in sie gebacken. Dadurch können Sie die Routen vollständig aus Ihrer Datei config/routes.rb entfernen.

einfach eine Initialisierung für Hochspannung einstellen:

# config/initializers/high_voltage.rb 
HighVoltage.route_drawer = HighVoltage::RouteDrawers::Root 

ich die oben auf einem Cedar-App auf Heroku eingesetzt und es lief wie erwartet.
