Question

我正在为Magento开发一个模块，它调用一个web服务并添加一个cookie。我希望在保存用户( customer_save_after )时调用类中的一个方法。在本地主机上开发时，我不知何故能够让它正常工作，但在我尝试实现它的活动站点上，我得到了这个错误：

Mage注册表项“_singleton/Eight18 18_Aqui4_Model_观察者”已经存在

有一个类似的线程这里，但它忽略了如何解决问题的实际细节。

下面是我的config.xml：( customer_save_after事件似乎是错误开始的地方)

Answer 1

短版本:您的生产系统运行在“编译器模式”，您还没有编译您的模块类。

您的生产服务器正在运行Magento的"编译模式“(自链接)打开。从错误消息Magento的日志记录可以看出

ERR (3): Warning: include(): Failed opening '/var/www/clients/client3/web4/web/includes/src/Eight18_Aqui4_Model_Observer.php' 
for inclusion (include_path='/var/www/clients/client3/web4/web/includes/src:.:/usr/share/php:/usr/share/pear')  in /var/www/clients/client3/web4/web/includes/src/Varien_Autoload.php on line 93

Magento正在includes/src寻找一个类。这就是放置编译类的地方。此外，PHP正试图包含一个完全强调的文件名Eight18_Aqui4_Model_Observer.php。这只有在编译器模式打开时才会发生。

当您将模块更改推送到生产中时，您需要重新编译模块。你可以从

System -> Tools -> Compilation

或使用命令行编译器脚本。

$ php shell/compiler.php
Usage:  php -f compiler.php -- [options]

  state         Show Compilation State
  compile       Run Compilation Process
  clear         Disable Compiler include path and Remove compiled files
  enable        Enable Compiler include path
  disable       Disable Compiler include path
  help          This help
