Circular Dependencies in Ruby

Question

Let\'s say we have two classes, Foo and Foo Sub, each in a different file, foo.rb and foo_sub.rb respectively.

foo.rb:

require \"foo_sub\"
class Foo
         


        

Answer 1

Another decent option is to use the autoload feature of Ruby.

It works like this:

 module MyModule
      autoload :Class1, File.join(File.dirname(__FILE__), *%w[my_module class1.rb])
      autoload :Class2, File.join(File.dirname(__FILE__), *%w[my_module class2.rb])
      # Code for MyModule here
 end

and is described well here:
