active_record has_many, :through and active _resource

Hello, I have many to many relationship between Venue and Catalog <pre> class Venue < ActiveRecord::Base   has_many :venue_catalogs   has_many :catalogs, :through => :venue_catalogs end

class VenueCatalog < ActiveRecord::Base   belongs_to :venue   belongs_to :catalog end

class Catalog < ActiveResource end </pre> when I call url /venues.xml I get undefined method `quoted_table_name' for Catalog:Class

seems belongs_to ActiveResource is not recognizing catalog is not an ActiveRecord.
