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.
