我是Magento的初学者，我从开发小型扩展开始。
我已经安装好了，一切都很好。但由于某种原因，我决定重新安装它。我从core_resource表中删除了行，我也从DB中删除了模块表。在.xml配置文件中我放错了
现在扩展功能无效（当然）。但它仍然显示在配置 - ＆gt;高级 - ＆gt;模块输出！我不明白为什么。我甚至刚从目录中删除了所有文件和文件夹，我清除了Magento缓存（实际上在我的系统中设置为“禁用”）
这是config.xml：

如何在这种情况下重新安装我的分机？请帮忙

完成this article工作，确保您对设置资源的功能，工作方式以及如何对其进行故障排除有任何误解。
一旦你完成了这一切，从你在这个问题线程中所说的一切，听起来你正在“安装”你的资源，但你的安装脚本永远不会运行。我的猜测是你在
中使用的版本号
//0.0.1 is your version number
mysql4-install-0.0.1.php
与您的模块版本不匹配
<modules>
<Nie_Nie>
<version>?.?.?</version>
</Nie_Nie>
</modules>
这些应匹配脚本运行。我认为 Magento足够智能，如果找到它们就可以运行以前的版本，但是设置资源中的代码很难跟上，所以我总是确保它们匹配。
无论如何，这里是你如何看到magento运行你的设置资源时试图运行的文件。删除与您的模块相关的core_resource中的所有条目。清除缓存。然后在安装程序类
File: app/code/core/Mage/Core/Model/Resource/Setup.php
protected function _modifyResourceDb($actionType, $fromVersion, $toVersion)
{
...
$sqlFilesDir = Mage::getModuleDir('sql', $modName).DS.$this->_resourceName;
if (!is_dir($sqlFilesDir) || !is_readable($sqlFilesDir)) {
return false;
}
...
$sqlDir->close();
if (empty($arrAvailableFiles)) {
return false;
}
...
$arrModifyFiles = $this->_getModifySqlFiles($actionType, $fromVersion, $toVersion, $arrAvailableFiles);
if (empty($arrModifyFiles)) {
return false;
}
然后修改它们以添加一些临时调试异常
if (!is_dir($sqlFilesDir) || !is_readable($sqlFilesDir)) {
throw new Exception("$sqlFilesDir not found");
return false;
}
...
if (empty($arrAvailableFiles)) {
throw new Exception("No files found to run");
return false;
}
...
$arrModifyFiles = $this->_getModifySqlFiles($actionType, $fromVersion, $toVersion, $arrAvailableFiles);
if (empty($arrModifyFiles)) {
throw new Exception("No valid upgrade files found to run for ");
return false;
}
throw new Exception("If you're getting here, we have a file. Remove your exceptions here and place one in your installer to make sure it's the one you think it is.");
重新加载页面，你会收到有关Magento无法找到的异常文本的抱怨。这应该足以帮助您跟踪Magento尝试运行的安装程序脚本，但无法找到。只需记住删除core_resource中的模块行并清除缓存。 （Magento缓存哪些模块需要检查安装/升级）
如果这不起作用，请开始深入研究applyAllDataUpdates的逻辑并弄清楚为什么该类不包含您的安装程序文件。
答案 1 :(得分：0)
解决。问题是因为我没有文件类：
Anglingdirect_Jobadverts_Model_Mysql4_Setup
现在没事了。我从项目文件夹中删除了此扩展文件并将其返回。然后安装脚本已经运行。
干杯
