magento：无法将产品添加到购物车 - 主键

Question

所以昨天，我的 magento ishop 坏了，我无法将任何产品添加到购物车。

当我点击“添加到购物车”时，它会将我重定向到购物车并说：

“无法将商品添加到购物车。”

这是我的日志：

我真的希望，有人会想出办法。

我以前见过这个问题。当数据库被写入 Magento API 之外并且出现问题时，就会发生这种情况。一个简单的解决方案是打开 MySQL 通用日志来记录所有 sql 查询。在命令行上使用 tail 程序和 -f 标志实时查看 mysql 常规日志，例如 tail -f general.log

现在尝试执行导致您违反完整性约束的操作，您应该会在日志中看到尝试的 sql 查询。有了这些信息，您应该能够更好地跟踪问题，如果需要，删除数据库中的错误条目。

有时它也会由于与产品相关的扩展而发生。在这种情况下，请禁用所有 3rd 方扩展，然后尝试添加产品。
