Firstly you can use the Laravel custom attribute option and you can define it in your Transactions Model like so
public function getTotalRefundAttribute() {
return $this->logTransaction ? $this->logTransaction->where('status', 3)->sum('amount_pay') : null;
}
And now when you get any Transaction instance it will have an extra attribute called total_refund where you can see the total amount. But make sure you actually have eloquent relations setup between Transaction and LogTransactions models
