    <p>The reason modules bootstraps enable autoload is because they extend Zend_Application_Module_Bootstrap which sets the autoloader in the constructor like so</p> <pre><code>public function __construct($application) { //... if ($application-&gt;hasOption('resourceloader')) { $this-&gt;setOptions(array( 'resourceloader' =&gt; $application-&gt;getOption('resourceloader') )); } $this-&gt;initResourceLoader(); //... } </code></pre> <p>This runs because the modules resource runs the bootstrap for each module in the init function ...</p> <pre><code> foreach ($modules as $module =&gt; $moduleDirectory) { $bootstrapClass = $this-&gt;_formatModuleName($module) . '_Bootstrap'; if (!class_exists($bootstrapClass, false)) { $bootstrapPath = dirname($moduleDirectory) . '/Bootstrap.php'; if (file_exists($bootstrapPath)) { $eMsgTpl = 'Bootstrap file found for module "%s" but bootstrap class "%s" not found'; include_once $bootstrapPath; if (($default != $module) &amp;&amp; !class_exists($bootstrapClass, false) ) { throw new Zend_Application_Resource_Exception(sprintf( $eMsgTpl, $module, $bootstrapClass )); } elseif ($default == $module) { if (!class_exists($bootstrapClass, false)) { $bootstrapClass = 'Bootstrap'; if (!class_exists($bootstrapClass, false)) { throw new Zend_Application_Resource_Exception(sprintf( $eMsgTpl, $module, $bootstrapClass )); } } } } else { continue; } } if ($bootstrapClass == $curBootstrapClass) { // If the found bootstrap class matches the one calling this // resource, don't re-execute. continue; } $moduleBootstrap = new $bootstrapClass($bootstrap); $moduleBootstrap-&gt;bootstrap(); $this-&gt;_bootstraps[$module] = $moduleBootstrap; } </code></pre> <p>The short answer is if you don't write the empty bootstrap files, you'll have to abstract some of this well functioning, well tested code into your own global bootstrap file, and then lose the flexibility of having bootstraps for you modules when / if you need to bootstrap them later in your app.</p>

    1. COThanks for explaining, it just feels counter productive and not really a best practice to just litter my modules with empty bootstrap classes just to enable module specific resource loading. Indeed when i want to bootstrap a module i should add a module bootstrap but since in ALL modules resource autoloading should be available i was wondering if there wasn't something in the Application scope that could configure this?

    2. COI understand. If they are empty they just seem useless, but in my experience, there's come a point in time in every application where I've needed to bootstrap my module. I use it for defining custom module specific routes, grabbing specific formatted config files for modules themselves, and other things like that. You can easily remove the need for it from your app by adding that code into your bootstrap, if it bothers you that much, but IMHO, it's not worth 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.
