    <p>I have had some trouble finding a solution to this. Basically, I have an embedded ruby each loop whose body is a partial being rendered for a certain sub group of a model. For instance:</p> <pre><code>&lt;li id="thing"&gt; &lt;% items.each do |i| %&gt; &lt;%= render :partial =&gt; 'item', :locals =&gt; {:i =&gt; i} %&gt; &lt;% end %&gt; &lt;/li&gt; </code></pre> <p>I was wondering if there was a way with jQuery, AJAX, or even just rails (I'm sure that each one has a implementable solution for me, and I'm interested in all of them) to refresh that list of items. The reason I would want to be able to do this is, currently, I have implemented the functionality to allow a now 'item' to be created or an existing 'item' be updated, again, without having to reload the page (the form comes up in a certain container on a button click in both cases), and I would like upon submission for the list to automatically be updated with the new information or new 'item.' Would it be a better approach to try and refresh the entire list? Or is there a way to append the newly created/updated object to the list of partials (as a partial) clientside?</p> <p>I tried the following statement, but I can't seem to avoid getting the "undefined method" error on render.</p> <p><code>$("#activeTab").append("&lt;%= escape_javascript(render :partial =&gt; 'item', :locals =&gt; {:i =&gt; Item.order(:created_at).last}) %&gt;");</code></p> <p>I figured this would be a good solution because once the page was navigated away and came back to, the list would be loaded again. This is just to append to the static list while you are still on the page.</p>

    1. COCan you include roughly what HTML that ruby code would result in? Also, is that list, the form and the form processing logic all on the same page?

    2. COThis view has a list of objects that are associated with the model that this view is for, so I'm grabbing this item partial from another model. The partial includes an uploaded photo or video, some metrics, etc. So nothing TOO complicated. The form, when the appropriate button is clicked, replaces the container holding the list temporarily, and upon submission, shows the list again. I just use jQuery .show() and .hide() methods in the click event handlers. The form is a rails form, so I use the syntax form_for ... Does that give a better idea? Thanks for taking the time :)

    3. COI'm sorry, but it's 3:45 am here so that is still not enough info for my brain to be able to picture the situation fully. As far as I can see, we have an html page in a browser and a server capable of spitting out html and reacting to ajax requests. Sorry, maybe I somehow know too little (nothing really) about Ruby to be of any help.

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).
