Hi,
I've set up a ModelAdmin to manage multiple models. Only one of these requires drag-and-drop sorting.
When I add add sorting capability to the ModelAdmin, it complains because the non sorted Model doesn't have a SortOrder field. How can I specify that GridFieldSortableRows is added only to the Model which is to be sorted?
My code is:
class DAdmin extends ModelAdmin {
public static $managed_models = array(
'PCategory',
'AItem'
);
static $url_segment = 'd-admin';
static $menu_title = 'dAdmin';
public function getEditForm($id = null, $fields = null) {
$form = parent::getEditForm($id, $fields);
$cName = $this->sanitiseClassName($this->modelClass);
$gridField = $form->Fields()->fieldByName($cName);
$gridField->getConfig()->addComponent(new GridFieldSortableRows('SortOrder'));
return $form;
}
}
Thanks.
VWD.
