factory class duplicate insert check in magento2

Question

I have created a model class as like below.

Vendor\Module\Model/Bulider.php

namespace Vendor\Module\Model;

use Magento\Framework\Exception\QualificationException;
 class Builder extends \Magento\Framework\Model\AbstractModel
{

   public function __construct(
    \Magento\Framework\Model\Context $context,
    \Magento\Framework\Registry $registry,
    \Magento\Framework\Model\ResourceModel\AbstractResource $resource = null,
    \Magento\Framework\Data\Collection\AbstractDb $resourceCollection = null,
    array $data = []
) {
    parent::__construct($context, $registry, $resource, $resourceCollection, $data);
}

/**
 * @return void
 */
public function _construct()
{
    $this->_init('Vendor\Module\Model\ResourceModel\Builder');
 }

}

then Vendor\Module\Model\ResourceModel\Builder.php

 namespace Vendor\Module\Model\ResourceModel;

 class Builder extends \Magento\Framework\Model\ResourceModel\Db\AbstractDb
{

protected $_builderFactory;

public function __construct(
    \Magento\Framework\Model\ResourceModel\Db\Context $context,
    \Vendor\Module\Model\BuilderFactory $_builderFactory
)
{
    $this->_builderFactory = $_builderFactory;
    parent::__construct($context);
}


public function _construct()
{
    $this->_init('builder_table', 'id');
}

public function builder($pid,$type,$id,$date) {
    $log = $this->_builderFactory->create();
    $log->setPId($pid);
    $log->setProductType($type);
    $log->setUnitId($id);
    $log->setCreatedAt($date);
    $log->save();
  }
}

I have injected this class in my controller and inserting data as like below.

class Save extends \Magento\Backend\App\Action
{

 protected $_builderResourceModel;
 protected $_storeManager;

 public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magento\Store\Model\StoreManagerInterface $storeManager,
    \Vendor\Module\Model\ResourceModel\Builder $builderResourceModel
 ) {
    $this->_storeManager     = $storeManager;
    $this->_builderResourceModel = $builderResourceModel;
    parent::__construct($context);
 }

 public function execute()
 {
   $result = array();// this is the model data
   $modelId = $result['id'];
   $date = date('Y-m-d H:i:s');
   foreach($result['core_units'] as $unit){
      $type = "C";
      $this->_builderResourceModel->builder($modelId,$type,$unit,$date);
   }

    foreach($data['optional_units'] as $option){
       $type = "O";
      $this->_builderResourceModel->builder($modelId,$type,$option,$date);
    }

   }
}

the current data structure is like below

A sample result data is given here

  Array
   (
     [id] => 2    
     [core_units] => Array
     (
        [0] => 31
        [1] => 63
     )
      [optional_units] => Array
    (
        [0] => 31
        [1] => 63
        [2] => 82
       )
     )

so, while inserting data i need to check for the duplicate data insert.

Before inserting i need to check if same data exist or not in the table, if data exist with same i need to update otherwise i need to insert new row.

Can this be achieved any other way. Please someone look into it and update me your ideas. Thanks

Modify builder method following way:

public function builder($pid,$type,$id,$date)
{
    $log = $this->_builderFactory->create();
    $log = $log->load($pid, 'p_id');
    if (!$log->getId()) {
        $log = $this->_builderFactory->create();
    }
    $log->setPId($pid);
    $log->setProductType($type);
    $log->setUnitId($id);
    $log->setCreatedAt($date);
    $log->save();
}
