Michael Hartl rails tutorial twitter @replies feature extension


I completed the Michael Hartl tutorial, and i’m trying to add the twitter like @replies feature to the app but I’m completely lost. Here is what I have so far.

I added the in_reply_to column to the Micropost Model and created a User, has_many through microposts relationship. I’m lost after that. Any assistance will be greatly appreciated.

User Model

 has_many :microposts, dependent: : destroy
has_many :replies, through: :microposts, source: :in_reply_to
Micropost Model
 class Micropost < ActiveRecord::Base
  attr_accessible :  content
belongs_to :  user
belongs_to :in_reply_to, class_name: "User"

Here’s a hint: how should in_reply_to get a value? Perhaps you could set it based on scanning the text of the micropost about to be created?

Thanks for the hint, i think thats one of the things i couldn’t figure out. It was a trial and error to get this far.
