No like in getResultArray

Hello, I previously used query builder $db->query("MY_QUERY");
Now decided to try the patterns method $builder->like(), in which I get something wrong... The error concerns the output function, but why?

Call to undefined method CodeIgniter\Database\MySQLi\Builder::getResultArray()

Controller

PHP Code:

   $model = new \Modules\Par\Models\ParModel();
    $par = $this->request->getPost('test');
    $data = [
      'query'  => $model->searchPart($par),
      ...
    ];
    echo view('Modules\Par\Views\viewTest', $data); 


Model

PHP Code:

 public function searchPart($data) {
    return $this->db->table('par')->like('title', $data);
  } 


View

PHP Code:

foreach ($query->getResultArray() as $row)
{
        echo $row['title'];
        echo $row['body'];
} 


Thanks!

I would first start with the Class and check the return values to ensure that the script returns exactly what you expect then continue to the next variable:

PHP Code:

$model = new \Modules\Par\Models\ParModel();

echo '<pre>';
print_r($model);
echo '</pre>';
die;
