    copied!<p>I have a layered partial scheme and am trying to write DRY code. I need to pass a variable into a partial and maintain its array status so that within the partial I can render another partial with the <code>:collection</code> parameter.</p> <p><strong>on this page I render the <code>'feed'</code> partial:</strong></p> <pre><code> %div.row %div.span6 %h1 Posts /Post feed =render 'feed',:locals =&gt; {:feed_items =&gt; @posts} %div.span6 %h1 Groups /Group feed =render 'feed', :locals =&gt; {:feed_items =&gt; @groups} </code></pre> <p><strong>Here is the <code>'feed'</code> partial:</strong></p> <pre><code>%ol -if feed_items.first.is_a?(Post) =render :partial =&gt; 'post_feed_item', :collection =&gt; feed_items -else =render :partial =&gt; 'group_feed_item', :collection =&gt; feed_items =will_paginate feed_items </code></pre> <p><strong>Currently gives me this error:</strong></p> <pre><code>undefined local variable or method `feed_items' for #&lt;#&lt;Class:0x007fa8e2aa8b00&gt;:0x007fa8e5405390&gt; </code></pre> <p><strong>UPDATE 1:</strong></p> <p>real error. final partial doesn't recognize component of the <code>:collection</code> passed to it:</p> <pre><code>undefined local variable or method `feed_item' for #&lt;#&lt;Class:0x007fa8e2aa8b00&gt;:0x007fa8e2c6d670&gt; </code></pre> <p><strong>final partial <code>'post_feed_item'</code>(layer 3?):</strong></p> <pre><code>%li.feed_item.row-fluid %div.image.span3 =link_to image_tag(feed_item.assets.empty? ? '/assets/small.png': feed_item.assets.first.image.url(:small), :alt =&gt; feed_item.title), post_url(feed_item) </code></pre> <p>So there is some problem in the first partial...<code>feed_items</code> isn't being parsed as an array?</p>
