You must overwrite #clone so that all associations are also cloned, like

class Category < ActiveRecord::Base
  has_many :products

  alias_method :original_clone, clone

  def clone
    category = self.original_clone
    category.products = self.products.clone
  end
end

... remember to do the same on Product and ProductVariant.

I think you should start from using "clone" method. Your problem, if I have understood it right, is that you want a recursive clone. Frankly, i don't know if it exists a general solution but I think you could clone you father/sons chain by hand. Maybe it isn't an elegant solution but it should work.
