rails rendering collection not working - undefined local variable or method

Question

I am trying to create a feed that displays all comments for a model.

_comments.html.erb

<% if @comments.any? %>
    <ol>
      <%= render partial: 'shared/comment_feed', collection: @comments %>
    </ol>
    <%= will_paginate @comments %>
<% else %>
    <h2>Be the first one to comment on this episode!</h2>
<% end %>

_comment_feed.html.erb

<li id="<%= comment.id %>">
  <%= link_to gravatar_for(comment.user), comment.user %>
  <span class="user">
    <%= link_to comment.user.name, comment.user %>
  </span>
  <span class="content"><%= simple_format comment.content %></span>
  <span class="timestamp">
    Posted <%= time_ago_in_words(comment.created_at) %> ago.
  </span>
  <% if current_user?(comment.user) %>
    <%= link_to "delete", comment, method: :delete,
                                   confirm: "Are you sure?",
                                   title: comment.content %>
  <% end %> 
</li>

The above code gives me an undefined local variable or method `comment' error. Doesn't rails automatically generate comment when a partial is used to render comments collections? Any help would be greatly appreciated.

The name of the local variable corresponds to the name of the partial. In your case the local variable is going to be named comment_feed.
