Rails 3类可供查看，控制器和模型

Question

I am thinking about creating a new class that does URL shortening that can be called from the view, controller or model. Where should I put this class?

Answer 1

这样的库应该位于lib ，您需要在使用它的文件中对其进行要求，或者在config/application.rb globaly中对其进行要求。

Answer 2

您始终可以将其转储到config/initializers除非您要将其打包为独立的gem。

Answer 3

If you place the class in /lib don't forget to make sure that it is autoloaded. In application.rb make sure you have a line like the following:

    # Custom directories with classes and modules you want to be autoloadable.
    config.autoload_paths += Dir["#{config.root}/lib/**/"]
