Quote class preference is not working

Question

I want to overwrite validateMinimumAmount function that is available in Magento\Quote\Model\Quote class.

Below is my di.xml

<?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\Quote\Model\Quote" type="Myname\Minamount\Model\Quote" />
</config>

below is my preference class:

namespace Myname\Minamount\Model;

class Quote extends Magento\Quote\Model\Quote
{

    public function validateMinimumAmount($multishipping = false)
    {
      // here my logic is going 
    }
}

At the time of di compile it is showing below error:

Class 'Myname\Minamount\Model\Magento\Quote\Model\Quote' not found#

Magento version : 2.4.3-p1

Thanks

Answer 1

Your preference class need to like this.

namespace Myname\Minamount\Model;

class Quote extends \Magento\Quote\Model\Quote
{

    public function validateMinimumAmount($multishipping = false)
    {
      // here my logic is going 
    }
}

Then run all magento commands and then check.
