    <p>I have a list of items and above it I have a few links that allow you to filter the list but after you click on these links once, WebBrick returns 304 Not Modified. The items in the list can be changed in the list and so these filter links are showing out of date information. My view looks like this:</p> <p>app/views/items/index.html.erb:</p> <pre><code>&lt;%= link_to 'All', {action:'filter', filter:'all'}, remote:true %&gt; &lt;%= link_to 'To Buy', {action:'filter', filter:'to_buy'}, remote:true %&gt; &lt;div id="items"&gt; &lt;%= render 'items' %&gt; &lt;/div&gt; </code></pre> <p>WebBrick is running in development mode so caching shouldn't be turned on. I could set the method to something other than GET but technically that wouldn't be correct. Is there any option to make sure link_to doesn't return cached content? I'm using Rails 3.2.13.</p> <p>app/controllers/items_controller.rb:</p> <pre><code>def filter case params[:filter] when 'to_buy' then @items=Item.where('to_buy=?', true) when 'all' then @items=Item.all end end </code></pre> <p>app/views/items/filter.js.erb:</p> <pre><code>$('#items').html("&lt;%=j render 'items' %&gt;"); </code></pre> <p><strong>UPDATE</strong></p> <p>The only solution I could come up with was to turn the link_tos into normal HTML links and get JQuery to do the ajax request with cache set to false:</p> <p>app/views/items/index.html.erb:</p> <pre><code>&lt;a href="javascript:;" class="filter_link" data-filter="all"&gt;All&lt;/a&gt; &lt;a href="javascript:;" class="filter_link" data-filter="to_buy"&gt;To Buy&lt;/a&gt; </code></pre> <p>app/assets/javascripts/items.js.coffee:</p> <pre><code>$('.filter_link').click -&gt; filter=$(this).data('filter') $.ajax "items/filter/#{filter}", cache:false </code></pre>

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).
