I have class X that takes much time to initialize itself. I want to make that class singleton and force its creation when rails application starts.
I've made the singleton:
class X @@instance = nil def self.instance if @@instance.nil? @@instance = X.new puts 'CREATING' end return @@instance end private_class_method :new end
The problem is that every time I use this class I see 'CREATING' in logs. I've tried to put creation of class in initializers
directory but it doesn't work either.
