I'm working on a module in Magento 2.1 and have to override validate function of this class Magento\Customer\Model\Address

This is what my di.xml contains:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
     <preference for="Magento\Customer\Model\Address\AbstractAddress" type="Mymodule\Module\Model\Address\AbstractAddress" />

and this is what my file contains:


namespace Mymodule\Module\Model\Address;

class AbstractAddress extends \Magento\Customer\Model\Address\AbstractAddress

    public function validate()
        $errors = [];
        if (!\Zend_Validate::is($this->getFirstname(), 'NotEmpty')) {
            $errors[] = __('Please enter the first name and last name.');
        return parent::validate();

But I'm still not able to override the model.

  • are you refresh cache.

You cannot override classes which does not injected via DI. This class used only as parent and does not injected in any contructors and does not created via ObjectManager.

To override this model you need to create preference on injected subtypes (\Magento\Customer\Model\Address, ...).

But preference is not good way to add functionality. You can write plugin on \Magento\Customer\Model\Address\AbstractAddress and easy solve your problem.

  • Problem solved by overriding \Magento\Quote\Model\Quote\Address class as it was inheriting \Magento\Customer\Model\Address\AbstractAddress.
