默认情况下不查找 lib 目录 [英] lib directory is not looked in by default

问题描述

我遵循 Ryan 的子域 railscast，其中 het 创建了一个使用的子域类在他的路线中并将其放在 lib 目录中.显然，我的 rails 应用程序默认不会在 lib 目录中查找(我的应用程序仅在我将 subdomain.rb 文件从 lib 移动到例如/app/models 时才启动)

I following Ryan's subdomain railscast where het creates a Subdomain class used in his routes and places it in the lib directory. Apparantly my rails app isn't looking in the lib dir by default (my app only starts when I move the subdomain.rb file from lib to eg /app/models)

我一直认为 lib 目录默认包含在 rails 应用程序中?我怎样才能最好地包含这个目录来实现这一点.

I always thought that the lib dir was included by default in a rails app? How can I best include this directory to make this happen.

谢谢

推荐答案

Rails 3 默认不会自动加载它(尽管 Rails 2 会).您必须将其添加到 application.rb 中的 autoload_paths.

Rails 3 does not autoload it by default (although Rails 2 does). You have to add it to your autoload_paths in application.rb.

module YourRailsApp
  class Application < Rails::Application
    config.autoload_paths += %W(#{Rails.root}/lib)
    #...
  end
end
