This may not be the problem, but why are you using eval?
ActiveSupport::CoreExtensions::String::Inflections defines constantize
as a method on String. It would seem to me that this would work:
(I18n.locale.capitalize + '::' + common_part).constantize
However, if you are looking for a class, investigate classify instead.
Maybe there's something I'm missing here that requires use of eval?
What happens in script/console if you type the expression in?
