title: Undefined method 'body' error for RoR tutorial
body: <p>New to ROR and am going through the tutorial: <a href="http://guides.rubyonrails.org/getting_started.html" rel="nofollow">http://guides.rubyonrails.org/getting_started.html</a> and when adding the comments section, I get an error in the app/views/posts/show.html file that "undefined method `body'. Here is the exact error:</p>
  
  <pre><code>undefined method `body' for #&lt;Comment:0x4157430&gt;
  
  Extracted source (around line #37):
  
  34:     &lt;/div&gt;
  35:     &lt;div class="field"&gt;
  36:         &lt;%= f.label :body %&gt;&lt;br /&gt;
  37:         &lt;%= f.text_area :body %&gt;
  38:     &lt;/div&gt;
  39:     &lt;div class="actions"&gt;
  40:         &lt;%= f.submit %&gt;
  </code></pre>
  
  <p>Thanks</p>
