编辑模块似乎没有效果

Question

我正在使用一个模块来计算基于物品重量的运输方法。该模块似乎安装，但如果我编辑主类，似乎没有任何反映在前端。

主要类扩展Mage_Shipping_Model_Carrier_Abstract见下图：

<?php 
class Laurensmedia_Advancedshipping_Model_Carrier_Advancedshipping  
extends Mage_Shipping_Model_Carrier_Abstract 
implements Mage_Shipping_Model_Carrier_Interface 
{ 

    protected $_code = 'advancedshipping'; 

config.xml文件看起来是这样的：

<?xml version="1.0"?> 
<config> 
    <modules> 
    <Laurensmedia_Advancedshipping> 
     <version>0.1.0</version>

</config> 

我曾尝试以下：

• 清除磁盘缓存
• 手动删除荷兰国际集团的/ var /缓存中的内容/
• 复制所有其它模块来../disabled/（有效 禁用它们）以上

没有一个似乎已经奏效。任何人都可以提供任何建议，为什么当我编辑主类文件什么都没有发生？即使我故意破坏文件（即 - 删除一半的代码），我甚至没有看到任何错误。

Answer 1

我没有看到<rewrite>在配置中声明为Laurensmedia_Advancedshipping_Model_Carrier_Advancedshipping。

这将解释为什么它没有被拾取，因为它似乎要重写一个标准的Magento类。

如果它不打算作为重写，该类如何被调用？
