HI there,
This could just be a Friday brain drain but for the life of me i can't workout/remember how to filter a dataset using a function on the model. I have a Runner data model and i wish to return all runners thats easy

$runners = Runner::get();
return $runners

but the next stage is to only bring back runners that are overdue at their checkpoint so i have a function on the model.
public function RunnerOverdue() {
    $distance = self::NextCP();
    $thetime = strtotime(self::TheLKPtime());
    if($distance and self::Pace() > 0){
          $nexttime = (($distance / self::Pace()) * 60 * 60);
          $current = time();
          $next = $thetime + $nexttime;
          if($current > $next){
                $overDue = true;
          } else {
                $overDue = false;
    return $overDue;

So what i want to do is only return the Runners that have a RunnerOverdue = true

I did this before about 12-18 months ago and it worked, now it doesnt, the old code was

function getOverdue() {
        $runners = Runner::get()->filter('RunnerOverdue()' > 0);
        return $runners;

any help or pointers please?

cumquat, would this work:

function getOverdue() {
        $runners = Runner::get()->filter('RunnerOverdue()', 1);
        return $runners;

Sounds like you’re looking for DataList::filterByCallback().

$runners = Runner::get()->filterByCallback(function($record) {
    return $record->RunnerOverdue();
return $runners;
