I have a model that has a boolean 'Approved'. If I have that as part of the summary field then its sortable by clicking on the header, but it shows 1 or 0 in the column. If I use Approved.Nice in the summary fields then obviously it calls a method and as a result it isn't searchable but it looks better saying 'Yes' or 'No'.

Seems like other people might've had other similar cases where a method is needed to display things nicely (date, names etc.,) but still sorting is important. Is there a solution or an add-on that can help with this?

Cheers,
Nick

Hi Dig,

Resurrecting your post and providing an answer courtesy of iRC:

class SomeModelAdmin extends ModelAdmin {
	private static $managed_models = array(
		"MyDataObject"
	);
	
	public function getEditForm($id = null, $fields = null) {
		$form = parent::getEditForm($id, $fields);
		
		$gridField = $form->Fields()->dataFieldByName('MyDataObject');
		$dataColumns = $gridField->getConfig()->getComponentByType('GridFieldDataColumns');
		$dataColumns->setDisplayFields(array(
			'Field' => array(
				'title' => 'Field name',
				'callback' => function($record) {
					return $record->dbObject('Field')->Nice();
				}
			)
		));
		
		return $form;
	}
