Rails 3库直到需要时才加载 [英] Rails 3 library not loading until require

问题描述

我试图将Tokbox SDK加载到rails 3中.我已将该库放置在/lib目录中，因此当前我的目录结构如下:

I'm trying to load the Tokbox SDK in rails 3. I've placed the library in my /lib directory, so currently my directory structure looks like so:

/lib
   opentok.rb
  /OpenTok
     Exceptions.rb
    OpenTokSDK.rb
    Session.rb

/lib
  opentok.rb
  /OpenTok
    Exceptions.rb
    OpenTokSDK.rb
    Session.rb

我正在使用application.rb中的以下内容加载/lib目录中的所有文件:

I'm loading all files in the /lib directory using the following in application.rb:

config.autoload_paths += %W(#{config.root}/lib)
config.autoload_paths += Dir["#{config.root}/lib/**/"]

我在/lib目录中拥有的其他文件都可以自动加载，但是在我添加require 'OpenTok'之前该库不会加载:

Other files I have in the /lib directory are auto-loading just fine, but this library does not load until I add a require 'OpenTok':

ruby-1.9.2-p0 > OpenTok
NameError: uninitialized constant OpenTok
ruby-1.9.2-p0 > OpenTok::OpenTokSDK
NameError: uninitialized constant OpenTok
ruby-1.9.2-p0 > require 'OpenTok'
 => ["OpenTok"]
ruby-1.9.2-p0 > OpenTok
 => OpenTok
ruby-1.9.2-p0 > OpenTok::OpenTokSDK
 => OpenTok::OpenTokSDK 

在Rails 3中加载库的正确方法是什么?

What is the correct way to load the library in Rails 3?

推荐答案

自动加载器将使常量变大，因此"OpenTok"将使自动加载器寻找"open_tok.rb"，而不是"opentok.rb".尝试重命名lib/opentok.rb，它应该可以正常工作.

The autoloader will snake case the constant, so "OpenTok" would make the autoloader look for "open_tok.rb", not "opentok.rb". Try renaming lib/opentok.rb and it should work fine.
