title: Rails 3 Form?, has a TextArea and Rails gives it an ID, but I'll have several on a page
body: <p>here is my partial for writing a comment:</p>
  
  <pre><code>&lt;div class="commentBox"&gt;
      &lt;%=form_for [commentable,Comment.new], :remote =&gt; true do |f|%&gt;
          &lt;%=f.text_area :content, :placeholder=&gt;"Write a comment...", :title=&gt;"Write a comment..." %&gt;
          &lt;%=f.hidden_field :parent_id%&gt;
          &lt;br /&gt;
          &lt;%=f.submit "Add comment"%&gt;
      &lt;%end%&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The issue with this is that the page is loading which the following:</p>
  
  <pre><code>....&lt;textarea title="Write a comment..." rows="20" placeholder="Write a comment..." name="comment[content]" id="comment_content" cols="40"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>The problem with this is that my page can have several items on it that are commentable. So having a TEXTAREA with ID doesn't work...</p>
  
  <p>What I'd like is for the textarea to have a class of comment_content, and then in the form I can add a hidden field with the recordID where the comment can live and then in the controller use that ID to insert into the DB. Does this sound like the right idea?</p>
  
  <p>Thoughts?</p>
