    <p>How to pass collections to Rails partials that contain a block. (Or, how to get around Rails magic).</p> <p>I have a feeling I'm think about this from the wrong angle. Can anyone point me in teh right direction?</p> <p>Say I have an index with two repeated blocks, like so:</p> <pre><code>&lt;div class="content"&gt; &lt;table&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;COL1&lt;/th&gt; &lt;th&gt;COL2&lt;/th&gt; &lt;th&gt;COL3&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;% @collectionA.each do |a| %&gt; &lt;tr&gt; &lt;td&gt;&lt;%= a.col1 %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= a.col2 %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= a.col3 %&gt;&lt;/td&gt; &lt;/tr&gt; &lt;% end %&gt; &lt;tr&gt;&lt;%= will_paginate @collectionA %&gt;&lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;br /&gt; &lt;table&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;COL1&lt;/th&gt; &lt;th&gt;COL2&lt;/th&gt; &lt;th&gt;COL3&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;% @collectionB.each do |b| %&gt; &lt;tr&gt; &lt;td&gt;&lt;%= b.col1 %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= b.col2 %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= b.col3 %&gt;&lt;/td&gt; &lt;/tr&gt; &lt;% end %&gt; &lt;tr&gt;&lt;%= will_paginate @collectionA %&gt;&lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;/div&gt; </code></pre> <p>My first round of DRYing up might look something like this.</p> <pre><code>... &lt;tbody&gt; &lt;%= render :partial =&gt; 'collections', :collection =&gt; @collectionA %&gt; &lt;/tbody&gt; &lt;%= will_paginate @collectionA %&gt; ... &lt;tbody&gt; &lt;%= render :partial =&gt; 'collections', :collection =&gt; @collectionb %&gt; &lt;/tbody&gt; &lt;%= will_paginate @collectionB %&gt; ... </code></pre> <p>But what if I need to move <code>will_paginate</code> into the partial as well, so that I can ajaxify it.</p> <p>If I only had one block, I would do</p> <pre><code>&lt;tbody&gt; &lt;%= render :partial =&gt; 'collection' %&gt; &lt;/tbody&gt; </code></pre> <p>and in the partial</p> <pre><code>&lt;% @collection.each do |col| %&gt; STUFF &lt;% end %&gt; &lt;%= will_paginate @collection %&gt; </code></pre> <p>But if I have two blocks, how can I pass @collection-A and @collection-B into the partial?</p> <p>Or am I looking at this the wrong way? Thanks for any pointers.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
