Body
I do not think there is one best practice, but I'll let you know what I do. <ol> <li>I have a series of js files each for with their own purpose in the <code>public/javascripts/</code> directory. Some examples could be <code>utility.js</code> <code>chat.js</code> <code>shopping_basket.js</code> and so on. </li> <li>I use <a href="http://github.com/sbecker/asset_packager" rel="nofollow noreferrer">asset packager</a> and define one big fat collection for all my general use functionality and another for admin only functionality. Round trips to the server cost way too much. I basically include all the js in on first page load minified into one blob (in general) </li> <li>I allow basic <code>$(document).ready</code> hooks inline in the pages, and keep them really short.</li> <li>Data that my js files needs to access is rendered inline with the page. (Usually in the DOM, sometimes as vars - Eg. <code>var xyz = 100</code>)</li> <li>I will usually develop my controllers with javascript off (and make sure it all works), then I turn it on and sprinkle a few <code>if request.xhr?</code> where needed.</li> </ol> <hr> Keep in mind, Rail 3.1 introduces a built-in best practice, see: <a href="http://guides.rubyonrails.org/asset_pipeline.html" rel="nofollow noreferrer">http://guides.rubyonrails.org/asset_pipeline.html</a> - on a personal note I have had performance and configuration issues with the new pipeline, however many others have had great success with it.

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.
