Polymorphic help

With the help of some devs. I was able to list down commends of a
specific deal using the “def comments” method in the deal model

However, what I also need is to display the owner/user who made the
comment via the @deal.comments loop. For example, something like this
would be ideal:

<% @deal.comments.each do |comment| %>
<%=h comment.comment %>
<%=h comment.user.first_name %>
<% end %>

Here is my actual code so far. I believe the key is to edit the “def
comments” method in the deal model class to include the user model or
something like that. Any help is appreciated…

deal show view

<% @deal.comments.each do |comment| %>

<% end %>

<%=h comment.comment %> <%= link_to ‘Show’, comment %> <%= link_to ‘Edit’, edit_comment_path(comment) %> <%= link_to ‘Destroy’, comment, :confirm => ‘Are you
sure?’, :method => :delete %>

class Deal < ActiveRecord::Base

validates_presence_of :title, :description, :price, :value, :discount,
:savings, :goal, :countdown, :purchased
