dbModel读取资源在magento中不实现Zend_Db_Adapter_Abstract [英] dbModel read resource does not implement Zend_Db_Adapter_Abstract in magento

问题描述

当我试图创建自定义模块并得到这个错误。
我只是将etc / local.xml的权限更改为644到646它错误来了
后，我回到644，但似乎相同的错误
许多论坛讨论这个问题。但不幸的是。我没有得到任何结果。
我清除缓存，重建索引。我还应该做什么来解决这一个。
Var文件夹权限设置777.即使我尝试新鲜的Magento安装，但相同的错误。

推荐答案

这个问题也可能会在你扩展错误类时到达

This problem may also arrived when you extend wrong class in

class Companyname_Recurringorders_Model_Mysql4_Recurringorders extends Mage_Core_Model_Abstract
{

class Companyname_Recurringorders_Model_Mysql4_Recurringorders extends Mage_Core_Model_Abstract {

public function _construct（）
{

public function _construct() {

    $this->_init('recurringorders/recurringorders', 'id_recurringorders');

 }

}

**
以下是正确的代码：

** Below is Correct Code :

class Companyname_Recurringorders_Model_Mysql4_Recurringorders extends Mage_Core_Model_Mysql4_Abstract
{

class Companyname_Recurringorders_Model_Mysql4_Recurringorders extends Mage_Core_Model_Mysql4_Abstract {

 public function _construct()
 {

     $this->_init('recurringorders/recurringorders', 'id_recurringorders');

 }

} **

这解决了问题
