How to update class override when upgrading module to new version in Prestashop?

Question

Let's say there is a module with version 0.1.

This module already have overrides applied for example to classes/Cart.php.

New requirement comes in and we make a change to an already overridden classes/Cart.php.

To apply new change we update module version to 0.2, but after update Prestashop doesn't reapply new overrides. I also tried placing upgrade script in upgrade folder which I confirmed was executing but old override is still there.

How do you apply new overrides without reinstalling the module?

Answer 1

在升级方法中，您可以按顺序运行uninstallOverrides和installOverrides，这将导致在当前版本中安装覆盖的状态。

文件升级/升级-1.1.0.php：

function upgrade_module_1_1_0($module)
{
    $module->uninstallOverrides();
    $module->installOverrides();
    return true;
}

Answer 2

我认为唯一的方法是手动删除新的覆盖文件并将其复制到/ override文件夹，检查当前覆盖的文件实际上是你的（md5 checksum p.ex。）。
