Magento2 override core file

Question

I am not able to override this file vendor/magento/module-sales-rule/Model/Rule/Condition/Address.php using preference.

<preference for="Companyname\Subtotalwithdiscount\Model\Rule\Condition\Address" type="Magento\SalesRule\Model\Rule\Condition\Address" />

Can someone guide me on this?

Answer 1

Try below code:

{{your name space}}/ {{Module name}}/etc/adminhtml/di.xml

<preference for="Magento\SalesRule\Model\Rule\Condition\Address" type="Companyname\Subtotalwithdiscount\Model\Rule\Condition\Address" />

There is sequencing issue in your code.

Note: Make sure your di.xml file is locate at etc/adminhtml/di.xml.

I hope it will help...!!!
