is it possible to implement a recursive foreign key association like
i'm writing a vocab app, where i want the vocab table to have an id
and two foreign keys, word1 and word2.
the word table will have an id, a word-string, and a language
i'm trying to do this as follows:
class Vocab < ActiveRecord::Base
class Word < ActiveRecord::Base
has_many :words, :through => :vocabs
but it doesn't work. I'm really new to rails and ruby.
