Rails 3 class available to view, controller and model

I 开发者_运维知识库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?

Such library should live in lib and you need to require it in file you use it or globaly in config/application.rb.

You can always dump it in config/initializers unless you'd want to package it up as an independent gem.

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/**/"]
