Rails-如何使用简单的ruby类？

Question

I have some simple ruby classes that I want to use with rails (they are classes for things like points, lines, rectangles, etc.). How can I use them with a rails controller or an active record model?

Thanks!

The convention is to put them in your-app/lib/ . You can have Rails automatically load them by configuring it to do so in config/application.rb . Edit the default to look something like this:

# Custom directories with classes and modules you want to be autoloadable.
config.autoload_paths += %W( #{Rails.root}/lib/shapes )

Where your class definition files are in your-app/lib/shapes .

Note : This is for Rails 3. Rails 2.x automatically loads files from lib.
