[FIXED] How do I use fixed fields in CakeDC's csvUpload behavior in Util plugin

Issue

I am using the csvUpload behavior of the Utils plugin by CakeDC, on a CakePHP 2.2.1 install.

I have it working great it's processing a rather large csv successfully. However there are two fields in my table / Model that would be considered fixed, as they are based on ID's from from associated models that are not consistent. So I need to get these fixed values via variables which is easy enough.

So my question is, how do I use the fixed fields aspect of csvUpload? I have tried that following and many little variation, which obviously didn't work.

public function upload_csv($Id = null) {
    $unique_add = 69;
    if ( $this->request->is('POST') ) {
        $records_count = $this->Model->find( 'count' );
        try {
            $fixed = array('Model' => array('random_id' => $Id, 'unique_add' => $unique_add));
            $this->Model->importCSV($this->request->data['Model']['CsvFile']['tmp_name'], $fixed);
        } catch (Exception $e) {
            $import_errors = $this->Model->getImportErrors();
            $this->set( 'import_errors', $import_errors );
            $this->Session->setFlash( __('Error Importing') . ' ' . $this->request->data['Model']['CsvFile']['name'] . ', ' . __('column name mismatch.')  );
            $this->redirect( array('action'=>'import') );
        }

        $new_records_count = $this->Model->find( 'count' ) - $records_count;
        $this->Session->setFlash(__('Successfully imported') . ' ' . $new_records_count .  ' records from ' . $this->request->data['Model']['CsvFile']['name'] );
        $this->redirect(array('plugin'=>'usermgmt', 'controller'=>'users', 'action'=>'dashboard'));
    }
}

Any help would be greatly appreciated as I have only found 1 post concerning this behavior when I searching...


Solution

I made my custom method to achieve the same task. Define the following method in app\Plugin\Utils\Model\Behavior

public function getCSVData(Model &$Model, $file, $fixed = array())
{
    $settings = array(
              'delimiter' => ',',
              'enclosure' => '"',
              'hasHeader' => true
            );
    $this->setup($Model, $settings);
    $handle = new SplFileObject($file, 'rb');       
    $header = $this->_getHeader($Model, $handle);
    $db = $Model->getDataSource();
    $db->begin($Model);
    $saved = array();
    $data = array();
    $i = 0;
    while (($row = $this->_getCSVLine($Model, $handle)) !== false)
    {
        foreach ($header as $k => $col)
        {
            // get the data field from Model.field              
            $col = str_replace('.', '-', trim($col));
            if (strpos($col, '.') !== false)
            {
                list($model,$field) = explode('.', $col);
                $data[$i][$model][$field] = (isset($row[$k])) ? $row[$k] : '';
            }
            else
            {
                $col = str_replace(' ','_', $col);
                $data[$i][$Model->alias][$col] = (isset($row[$k])) ? $row[$k] : '';
            }
        }
        $is_valid_row = false;

        foreach($data[$i][$Model->alias] as $col => $value )
        {
            if(!empty($data[$i][$Model->alias][$col]))
            {
                $is_valid_row = true;                   
            }
        }
        if($is_valid_row == true)
        {
            $i++;
            $data = Set::merge($data, $fixed);  
        }
        else
        {
            unset($data[$i]);
        }
    }
    return $data;
}   

And you can use it using:

  $csv_data = $this->Model->getCSVData($this->request->data['Model']['CsvFile']['tmp_name'], $fixed);

Here $csv_data will contain an array of all of those records from the csv file which are not empty and with the fixed field in each record index.
