class UserComment < ActiveRecord::Base belongs_to :user belongs_to :creator, :class_name =>“User”, :foreign_key =>“poster_user_id” end
Then reference user.user_comment.creator.login .
See the api for ‘belongs_to’ for more on this.
you are probably going to want to add
class User < ActiveRecord::Base has_many :user_comments # add the line below has_many :posted_comments, :class_name => "UserComment", :foreign_key => :posted_user_id end
so that you can get to the comments that were posted by a particular user.
