title: RoR v2.3 Model associations
body: <p>I was wondering how I'm suppose to associate my <code>User, Post, and Comment</code> models. It is suppose to be like so: The user can comment on any post and a post belongs to a user with a Boolean for being admin. I have been scratching my had for awhile trying to figure this out but nothing has made any sense at all.</p>
  
  <p>Any help would be greatly appreciated.</p>
