Import filters: unable to set default values?

[krazykit]

Software: Xataface 2.0alpha1
Issue: Unable to set "Default Values" during data import on the Import Records Form

I've managed to write an import filter and make Xataface read it in correctly. The imported records will show up in the preview pane just fine, but I can't set any default values when I'm trying to import. The "Default Values" just shows the headers "Key" and "Value", but no way to enter any data (I'd post a screenshot, but phpbb is whining that it looks too spammy).
I don't see any reason that this wouldn't show up: is there something that I'm missing in an ini file or something? The Import Filters how-to page suggests that it should "just work". I can upload ini files or code as needed. Thanks in advance.

Can you post your import filter code? Are you specifying the default values at using the import form at the time that you perform the import? Or are you referring to default values that are specified at the database definition level (or the fieldname__default() method of the delegate class)?

Code: Select all

<?
import('tables/common/fasta.php');

class tables_genesequences {

function __import__fasta(&$data, $defaultValues=array()){
        #declare the dataface records
        $app =& Dataface_Application::getInstance();
        $output = array();
        $record = new Dataface_Record('genesequences', array());
        $record->setValues($defaultValues); #set the defaults for dataface
        $records = array();

        #run the data through read_fasta for an array with the data
        #array( $header, $sequence);
        $output = read_fasta($data);
       
        //well, i know how to do this as a loop...
        foreach($output as $vals)
        {
            $record -> setValues( array(
                                    'header' => $vals['header'],
                                    'sequence' => $vals['sequence']
                                       )
                                );
            $records[] = $record;
        }

        return $records;
        }
}
?>


the read_fasta() function simply returns an array with an array for each header,sequence pair.

edit: here's my fasta.php, not that it should matter:

Code: Select all

function beginsWith( $str, $sub ) {
    return ( substr( $str, 0, strlen( $sub ) ) === $sub );

function read_fasta( $source )

        // split each line
        $source_array = explode("\n", $source);
        $pos = -1;
        $seqinfo = array();

        foreach ($source_array as $line)

                // do we find > .... then this is a new sequence
                $new_sequence   = strpos($line, ">");
                $new_note       = strpos($line, ";"); # older

                if( beginsWith($line, ">") || beginsWith($line, ";"))
                {
                    $pos = $pos +1;
                    $seqinfo[] = array('header' => $line, 'sequence' => '');
                }
                else
                {
                    $seqinfo[$pos]["sequence"] .= $line;
                }
        }
    return $seqinfo;

Initialize the record inside the array:

Code: Select all

$record = new Dataface_Record('genesequences', array());
  $record->setValues($defaultValues); #set the defaults for dataface


It looks like you are adding the same record to each entry in the array. This probably means that every row in your preview has the same values.

Thank you for your reply and pointing out the fix for the error in my code, but unfortunately, that was not my issue. Perhaps I was unclear: I am unable to set default values from the Xataface Import Records form itself: there are no drop-downs or text-fields to set defaults when importing from the web page. Please see the attached image.

Are there any javascript errors on that page? Are you using permissions/i.e. does this user have full permissions?

Looks like the problem was on my end: apparently, my Adblock list was filtering out "addRow". Whitelisting the site (or removing the offending entry) fixes this. Importing now works as expected.
