Hi there,

I am struggling to convert the code below from the tutorial (http://doc.silverstripe.org/sapphire/en/tutorials/3-forms) to Silverstripe 3. I understand using DataList is a recommend approach and DataObjectSet is depreciated, but it seems that Group By is not supported in DataList.
Anyone has idea how to make the code working using SilverStripe 3’s new ORM like http://www.silverstripe.org/silverstripe-3-s-new-orm/ ?

function BrowserPollResults() {
$submissions = DataObject::get('BrowserPollSubmission');
$total = $submissions->Count();

$doSet = new DataObjectSet();
foreach($submissions->groupBy('Browser') as $browser => $data) {
$percentage = (int) ($data->Count() / $total * 100);
$record = array(
'Browser' => $browser,
'Percentage' => $percentage
);
$doSet->push(new ArrayData($record));
}

return $doSet;
}

Hey,

for simmilar functionality you can use GroupedList:

$groupedSubmissionsList = new GroupedList($submissions);
$grouped = $groupedSubmissionsList->groupBy("Browser");

Cheers
