From the PHPMag.ru site comes a recent post looking at a technique for creating auto-loading models in your Zend Framework application.
When it comes to MVC, ZF handles almost everything - your action controllers are triggered, your views are loaded, w/o you having to worry about them. Not the same with models. If you comply to directory layout advised by ZF, you have "models" folder, but framework doesnâ€™t interact with it in any way.
There's a three step process he includes to make your models autoload - extend the Zend_Controller_action for the controller you're working with, put loadModel() method into the controller (what will actually load the models) and an optional third step of adding in class autoloading. A few alternatives are also mentioned: Zend_Load_PluginLoader, Zend_Load subclassing and a controller plugin.
