rails: self-referential association
- by john
hi,
My needs are very simple: I have a Tip table to receive comments and have comments to receive comments, too.
To retrieve each comment that is stored in the same table (comments), I created another key for the comments on comments: "inverse_comments".
I tried to use one comments table by using self-referntial association. Some resources seem to bring more than one table into the piture which are diffent from my needs. So I came up whth the following modeling for comments:
class Comment < ActiveRecord::Base
belongs_to :tip
belongs_to :user
has_many :mycomments,
:through => :inverse_comments,
:source => :comment
end
Apparently something is missing here but I cannot figure it out.
Could some one enlighten me on this:
what changes I need to do to make the model work?
thanks.
