title: Adding a delete link for nested attributes
body: <p>I have nested attributes in my show.erb and I create a blank nested attribute and show a grid of items with the blank at the bottom like so.</p>
  
  <pre><code>&lt;%= form_for @question do |q| %&gt;
    &lt;% q.fields_for :answers, @question.answers do |l| %&gt;
      &lt;tr&gt;
  
        &lt;td&gt;&lt;%= l.text_field :text %&gt;&lt;/td&gt;
        &lt;td&gt;&lt;%= l.check_box :correct %&gt;&lt;/td&gt;
        &lt;td&gt;&lt;%= l.text_field :imagename %&gt;&lt;/td&gt;
        &lt;td&gt;&lt;%= l.number_field :x %&gt;&lt;/td&gt;
        &lt;td&gt;&lt;%= l.number_field :y %&gt;&lt;/td&gt;
      &lt;/tr&gt;
    &lt;% end %&gt;
  
    &lt;tr&gt;
          &lt;td colspan=5 align=right&gt;&lt;%= submit_tag '+' %&gt;
    &lt;/tr&gt;
  
  &lt;% end %&gt;
  </code></pre>
  
  <p>I want a link_to 'Destroy' to work but i'm getting <code>undefined method 'plural'</code> when i add this to the grid </p>
  
  <pre><code>&lt;%= link_to 'Destroy', l, :controller =&gt; "answer", :confirm =&gt; 'Are you sure?', :method =&gt; :delete %&gt;
  </code></pre>
