You did not mention that the article has a user_id. I thought that was comments that had user_id. However since it does have a user_id then assuming you have set up the models correctly you should be able to say @user = @article.user > @comments = @article.comments > impressionist(@snippet) > end > > Each comment contains the following: content, user_id, article_id. > > I can get the content and the user_id's associated to the article > > <%= comment.content %> > <%= comment.user_id %> > > This is a test comment user_id: 14 > This is yet another thrilling test comment user_id: 15 > > What I'd like is comment.username so I can get the users name, but that > is throwing me for a loop.

Again you should just be able to use comment.user.name If that does not work show us the most important information, which is how you have defined the relationships in the models (has_many, belongs_to etc).
