Deep nested associations on the same Model
...submit a Story and this can then be forked by another user and worked on
seperately. To acheive this I have a has_many association within the
same Story model as such:
class Story < ActiveRecord::Base
has_many :forked_stories, :class_name => ''Story'', :foreign_key =>
:parent_story_id
belongs_to :parent_story
end
In this way if a single story is an original it''s parent_story_id will
be nil. Similarly, if I call @story.forked_stories I can get a
collection of all the stories that have been forked from the current
one, or @story.parent_story will return the story...
