How to get rid of an ActiveRecord warning "already initialized constant"

I need to get a proxy class for a specific AR validation

I reuse a piece of code (from Globalize), where it's set as a constant :

module Globalize   module Model     module ActiveRecord       class << self         def create_proxy_class(klass)           Object.const_set "#{klass.name}Translation", Class.new (::ActiveRecord::Base){..} .. end

so in my validation module, I can write : translation_class = Globalize::Model::ActiveRecord.create_proxy_class (self.class) no problem when executing it...

but in my model unit tests, I execute it many times, and I get the warning... warning: already initialized constant EnumerationTranslation (when my model class is Enumeration of course)

can I delete this constant in my test setup ? how ?

thanks fyh
