    //get the object
    $report = $this->csv_m->getCSV();

    $newline = "\r\n";
    $new_report = $this->dbutil->csv_from_result($report, $delimiter, $newline);

    $this->load->helper('download');
    $data = file_get_contents($this->file_path . '/csv_file.csv');
    $name = 'name-'.date('d-m-Y').'.csv';
