validates_existence_of:
This method can be used for both Active records as well as Active Resources - ie anything that responds to 'exists?'. It has been tested to work with Rails v2.2+ and supports all options that validates_each does (like allow_nil, if, unless, etc) and a couple of additional ones (resource_name => the attribute name that might be based on a domain concept; and resource_class => that could be derived from the resource name, but could be namespaced, etc). Here is the code:

          def validates_existence_of(*attributes)
            options = {:message => 'does not exist'}.merge(attributes.extract_options!)
            validates_each(attributes, options) do |record, attr, value|
              resource_name = options[:resource_name]
              resource_name ||= attr.to_s.gsub(/_id$/, "") if attr.to_s =~ /_id$/
              resource_name || attr.to_s  # last resort
