Magento 2: Override ACL using custom module

Question

I have updated the parent of a menu item which is coming from a third party extension. I have updated the menu item by my custom module's menu.xml file.

For instance, the menu was coming under Marketing >> Promotions >> Gift Card History. I have changed the menu position to Reports >> Others >> Gift Card Accounting by using the following code:

<update id="Magestore_Giftvoucher::gifthistory" title="Gift Cards Accounting" sortOrder="40" parent="Stream_ChangeCoreMenuPosition::others"/>

Since the parent of the menu item has been changed, now I need to modify the ACL of this item also.

For this, I don't want to make changes in the extension's acl.xml file. So I have created my own acl.xml in my custom module, but when I add the ACL entry for the modified menu position, I get the following error:

Please help me, how can I modify the ACL of the extension using my custom module (without modifying the extension's files).

Answer 1

you need to create a plugin to disable the existing ACL record first

In di.xml

<!-- remove existing record from ACL -->    
<type name="Magento\Integration\Helper\Data">
    <plugin name="my-acl-data" type="VendorName\ModuleName\Plugin\Integration\Data" sortOrder="100" />
</type> 

VendorName\ModuleName\Plugin\Integration\Data.php

namespace VendorName\ModuleName\Plugin\Integration;

class Data
{
    public function beforeMapResources(\Magento\Integration\Helper\Data $helper, array $resources)
    {
        $removed = $this->getIdsToRemove();
        foreach ($resources as $key => $resource) {
            if (in_array($resource['id'], $removed)) {
                unset($resources[$key]);
            }
        }
        return [$resources];
    }
    private function getIdsToRemove()
    {
        return [
            'Magestore_Giftvoucher::gifthistory',
        ];
    }
}

This will remove Magestore_Giftvoucher::gifthistory

Then add your own records in acl.xml : VendorName_ModuleName::yourRecord
