Initializing a Global Instance of a Ruby Class

Hello,

I want to have an instance of a Ruby class I wrote initialized as a single instance on app startup, and have that instance accessible from my controllers. I assume this is simple, but have not been able to figure this out.

Where do I initialize the class? And how can I access it from my controllers?

I assume it is something like (env.rb......

''' $myclassinstance = MyClass.new ''' and then (foobar-controller.rb........ ''' def foo   @myvars = $myclassinstance.mymethod( params[:somevar] ) end ''' Thanks for reading,

M
