Ruby on rails Heroku网站因Rails 3.2.9和路由限制而崩溃

我的网站位于Heroku，在Rails 3.2.8上运行良好。我将路由约束类与高压gem一起用于静态（大部分）网页： routes.rb：

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

我在

/lib/constraints/static\u page.rb中有一个文件：

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

require 'constraints/static_page'

问题是，我刚刚更新到Rails 3.2.9，做了一次git push heroku，我的应用程序崩溃了：(

显然，Ruby/Heroku找不到我的
约束：：StaticPage
类。我的
路由顶部有
require
d。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

require 'constraints/static_page'

Rails 3.2.9中是否发生了一些变化，不再适用于Heroku？在本地，一切正常，只是在Heroku中没有。如果在我的路线中去掉该约束，一切正常（除了没有这些约束）。以下是我的
Heroku日志
