I think I found it ... (taskable is the instance, but model_name needs to run on the class, so add .class): Contact belongs_to :person 011:0> contact.person.model_name NoMethodError: undefined method `model_name' for #<Person:0xaa16a44> ... 012:0> contact.person.class.model_name => "Person" I have not tried on polymorphic, but I presume it would work too.
