There are two action helpers for doing exactly this. you can re-use your actions for multiple contexts with the ajaxContext or contextSwitch action helpers. The context switch is generally the more useful in my experience, and it can even automatically serialize the data you assign to the view in your action for json responses so there is no need for a view script. you initialise the context switch like this: <pre><code>class MyController extends Zend_Controller_Action { public function init() { $contextSwitch = $this->_helper->getHelper('contextSwitch'); $contextSwitch->addActionContext('index', 'json') ->initContext(); } public function indexAction() { $this->view->items = My_Model::fetchAll(); } } </code></pre> The above will add a context of json to the context switch, and when the action is called with the request parameter 'format' set, it will automatically serialize the content, in this case giving a json array of the items returned by My_Model::fetchAll(); The format parameter can either be passed in the url "/my/index/format/json" or with a get query "/my/index?format=json" The real magic is that the context switch also sets the appropriate headers for the response type, such as content-type. You can even specify your own contexts, and the headers to send.

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.
