Has anyone had any experience of using nested attributes with polymorphic associations ? I cannot see how it would work as the model would need to know the class of the object to create (when creating a new record for the association). Here is an example class MyClass < ActiveRecord::Base belongs_to :owner, :polymorphic=>true accepts_nested_attributes_for :owner end This generates a method called 'owner_attributes=' which is fair enough, but it does not generate the method 'build_owner' which is required by the looks of it. So, if I try using owner_attributes=, then straight away it complains that the method build_owner is missing. Regards Gary Taylor

If MyClass belongs to your :owner model, wouldn't the :owner model be the one that accepts nested attributes for MyClass?
