Question

My application uses a polymorhpic relationship like so:

class Child < ActiveRecord:Base
  belongs_to :child_owner, polymorphic: true
end

class Parent < ActiveRecord:Base
  has_many :children, as: :child_owner, dependent: :destroy
end

This setup works fine. However, when I change the attribute name of :children to a multiword variable like :kids_of_parent, I get an unintialized constant exception (for Parent::KidsOfParent). In my case, the multiword variable would be much more descriptive. What am I doing wrong? Can someone at least confirm this behaviour?

Thanks,

I think you should specify a class when use the name unconventional, like this:

has_many :kids_of_parent, as: :child_owner, class_name: "Child", dependent: :destroy
