Alright. Short and simple this time. Here is the code for
snippets/show.html.erb (showing the article):
<div class="span4">
<h1>Comments (<%= @snippet.comments.count %>)</h1>
<hr>
<% if signed_in? %>
<%= render 'shared/comment_form' %>
<% end %>
<% if @snippet.comments.any? %>
<%= render @comments %>
<% else %>
<p>There are no comments on this snippet.</p>
<% end %>
</div>
Here is comment.html.erb being showed by render @comments:
<div class="comment_container">
<%= gravatar_for comment.user, :size => 30 %> <span
class="username"><%= link_to comment.user.username, comment.user %>
commented <%= time_ago_in_words comment.created_at %></span>
<div class="comment_content"><%= comment.content %></div>
</div>
That is the code that isn't working and is giving the error. The only
thing that will display is comment.content.
And here is the log output. Seems to be properly getting the user data
for each comment, but comment.user isn't working. If I'm way off, let me
know again. At the very least I'm learning to better communicate issues
on this style of forum (sadly at the expense of peoples time).
