无法配置EAV设置资源

Question

我正在尝试创建一个EAV模块，并且我在这里停留了很长时间。

错误消息：

    Invalid entity_type specified: gagan_eavfaq

资源：

    <?php

class Gagan_Eavfaq_Model_Resource_Eav_Mysql4_Eavfaq
extends Mage_Eav_Model_Entity_Abstract
{

    public function _construct() {
        $resource = mage::getSingleton('core/resource');
        $this->setType('gagan_eavfaq');
        $this->setConnection(
                $resource->getConnection('eavfaq_read'),
                $resource->getConnection('eavfaq_write')
                );
    }
}

设置：

    <?php

class Gagan_Eavfaq_Entity_Setup extends
Mage_Eav_Model_Entity_Setup{

}

安装脚本： 我想要显示此异常。看起来我的设置没有找到这个文件的方法，由此我可以得出结论我的配置有问题。但我已经检查过几次仍然没有运气。请帮忙。谢谢

    <?php   $installer = $this;
throw new Exception("set up configured ");
