How about a nested hash of attributes?

class PostsController attr_accessible: :title, :body, :related_links => { :href, :title } end

This would accept the attributes: post_title, post_body, post_related_links_0_href, post_related_links_0_title, posts_related_ink_1...

The names might not be right. I forget exactly how rails names fields. But you get the point, yes?
