    <p>In your controller you should be able to do something as simple as:</p> <pre><code>@filtered_venues = Venue.where(:area =&gt; params[:venue][:area], :type =&gt; params[:venue][:type]).all </code></pre> <p>That should give you the filtered results that you want.</p> <p>And then in your view you should be able to use form helpers to create the select elements:</p> <pre><code>select("venue", "area", ['New York', 'London', 'Amsterdam'], {}, { :prompt =&gt; 'Select Area' }) select("venue", "type", ['Pub', 'Outdoor', 'Hall'], {}, { :prompt =&gt; 'Select Type' }) </code></pre> <p>Should output something like:</p> <pre><code> &lt;select name="venue[area]"&gt; &lt;option value=""&gt;Select Area&lt;/option&gt; &lt;option value="New York"&gt;New York&lt;/option&gt; &lt;option value="London"&gt;London&lt;/option&gt; &lt;option value="Amsterdam"&gt;Amsterdam&lt;/option&gt; &lt;/select&gt; &lt;select name="venue[:type]"&gt; &lt;option value=""&gt;Select Type&lt;/option&gt; &lt;option value="Pub"&gt;Pub&lt;/option&gt; &lt;option value="Outdoor"&gt;Outdoor&lt;/option&gt; &lt;option value="Hall"&gt;Hall&lt;/option&gt; &lt;/select&gt; </code></pre> <p>There are a lot of other ways to get the options in there dynamically if you have collections ready for area or type.

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.
