Constant Global object on a Ruby on Rails server

Question

Working with Rails 3.2.1 and Ruby 1.9.3, where is the proper place to initialize a Global constant object such that it is only initialized once when the rails server is started.

Right now I am declaring it as instance object as and it is initialized every time the method is called:

@object_wanted_to_be_global_const = Gemname::GemnameClass.new 'input'

Where is the best place to declare this as a global constant variable?

If declared as a global instead of an instance, how will this affect performance as the variable is accessed on almost every request?

Answer 1

Put this in an initializer.

And to respect Ruby's convention, capitalize the whole name.

I can't see any performance issue regarding this method.
