Php 自定义扩展名中的magento mysql安装文件

我在magento中有一个扩展，在安装时可以正常工作，但在我重置/重新启动扩展时（因为我添加了更多属性，只有在重新加载扩展时才会显示这些功能）通过删除数据库中的core_资源，我以前在另一个模块中使用过这种技术，效果很好，但是这个扩展给了我一个错误

所以我在整个站点上都遇到了巨大的错误，所以我检查了var/报告，它说扩展名的安装文件中有一个错误（因为它试图重新加载安装文件，但它必须与创建或覆盖第一次创建但未在数据库中删除的表有关，因为它们应该保留，因为保存的是数据，删除这些表将导致再次输入数据。）

因此，请参阅下面的安装文件，它似乎是导致问题的原因

当您从core_资源中删除模块名称时，下次加载站点时，它将尝试创建数据库，因为magento认为该模块确实存在（并且您将得到一个站点错误）。您可以做的是创建更新（更改该模块的版本号）

当您从core_资源中删除模块名称时，下次加载站点时，它将尝试创建数据库，因为magento认为该模块确实存在（并且您将得到一个站点错误）。您可以做的是创建更新（更改该模块的版本号）请看Ok，谢谢R.S会给我这个机会，因为我可能根本不需要删除核心资源，就像你说的，只需集成升级脚本。我通常做的是在开发环境中创建我的新模块，根据需要添加表/字段。一旦我的模块按需工作，我就创建我的安装/更新脚本。
