[QGIS-Developer] pyqgis - layer.saveDefaultStyle() for PostGIS layers

[Luigi Pirelli]

from the code:

mLayer->saveStyleToDatabase and mLayer->saveDefaultStyle

and in
QString QgsMapLayer::saveDefaultStyle( bool & theResultFlag )
{
  return saveNamedStyle( styleURI(), theResultFlag );
}

=> seems you are doing correct.

any log message?

******************************************


void QgsVectorLayerProperties::saveDefaultStyle_clicked()
{
  apply();
  QString errorMsg;
  if ( mLayer->dataProvider()->isSaveAndLoadStyleToDBSupported() )
  {
    QMessageBox askToUser;
    askToUser.setText( tr( "Save default style to: " ) );
    askToUser.setIcon( QMessageBox::Question );
    askToUser.addButton( tr( "Cancel" ), QMessageBox::RejectRole );
    askToUser.addButton( tr( "Local database" ), QMessageBox::NoRole );
    askToUser.addButton( tr( "Datasource database" ), QMessageBox::YesRole );

    switch ( askToUser.exec() )
    {
      case 0:
        return;
      case 2:
        mLayer->saveStyleToDatabase( "", "", true, "", errorMsg );
        if ( errorMsg.isNull() )
        {
          return;
        }
        break;
      default:
        break;
    }
  }

  bool defaultSavedFlag = false;
  errorMsg = mLayer->saveDefaultStyle( defaultSavedFlag );
  if ( !defaultSavedFlag )
  {
    QMessageBox::warning( this, tr( "Default Style" ), errorMsg );
  }
}
