Zend Action Helpers无法通过Action HelperBroker加载

Question

In my module bootstrap:

<?php

class Api_Bootstrap extends Zend_Application_Module_Bootstrap
{
    protected function _initAllowedMethods()
    {
        $front = Zend_Controller_Front::getInstance();
        $front->setParam('api_allowedMethods', array('POST'));
    }

    protected function _initActionHelperBrokers()
    {
        Zend_Controller_Action_HelperBroker::addPath(APPLICATION_PATH . '/modules/api/controllers/helpers', 'Api_Controller_Action_Helper_');

        Zend_Controller_Action_HelperBroker::addHelper(new Api_Controller_Action_Helper_Model());
    }
}

There is a Api_Controller_Action_Helper_Model at /var/www/project/application/modules/api/controller/helpers/Model.php

But I get:

PHP Fatal error:  Class 'Api_Controller_Action_Helper_Model' not found in /var/www/accounts.amh.localhost/application/modules/api/Bootstrap.php on line 15

As far as I can tell from the API and http://akrabat.com/zend-framework/using-action-helpers-in-zend-framework/ this should work.

I'm pretty sure this isn't a bootstrapping issue like I have had before, as I am specifically add the path/prefix right before trying to add the helper.

What else might I have missed?

The problem here is that the module autoloader does not know about controller action helper resources.

Try something like this in your module bootstrap

protected function _initResourceLoader()
{
    $resourceLoader = $this->getResourceLoader();

    $resourceLoader->addResourceType('actionhelper',
            'controllers/helpers', 'Controller_Action_Helper');
}

All that being said, as your helper has an empty constructor, you could omit the addHelper() line and just let the broker automatically create it when requested in your controllers, eg

$helper = $this->getHelper('Model');
