递归包括所有模型子目录 [英] Recursively including all model subdirectories

问题描述

如何在模型目录和lib目录中递归加载所有目录?在application.rb中，有以下几行:

How do you load all directories recursively in the models and lib directories? In application.rb, I have the lines:

config.autoload_paths += Dir[Rails.root.join('app', 'models', '{**}')]
config.autoload_paths += Dir[Rails.root.join('lib', '{**}')]

但是它们似乎只添加了一层模型和lib子目录.

but they only seem to add one level of model and lib subdirectories.

谢谢

推荐答案

这应该有帮助

 Dir["#{config.root}/app/models/**/","#{config.root}/lib/**/"]

享受！ (:

更新:

一个很好的问题，上面的例子只是我提到我最近的项目.

Excellent question, posting example above i have simply referred to my recent project.

进行了一些测试之后，我得到了更好的理解，这很棒.

After making some tests, better understanding comes to me and it is great.

主要区别当然不是File的join方法不是config.root/Rails.root

The main difference is of course neither in join method of File not config.root / Rails.root

在'**'之后尾随'/'是有意义的.

Trailing '/' after '**' makes sense.

第一个聊天时会说匹配仅目录. 第二个演讲是递归.

First one talks to match only directories when globbing. Second one talks do it recursively.

在您的情况下，这也很合适

In your case this one could be also appropriate

Dir[ Rails.root.join('app', 'models', '**/') ]
