Moved to ActiveRecord::Calculations::ClassMethods

misaka ยท Aug 28, 20083 thanks

It appears that this method has simply been moved to the module ActiveRecord::Calculations::ClassMethods. You can still use the example listed in the docs here, it will simply call the method ActiveRecord::Calculations::ClassMethods#count.
