Silverstripe Version: 4.5.1
Question:
Is there a bug if I want to manage a Time field with ModelAdmin? I get a 500 internal server error, but could not find any issue or bug report regarding this. How can I avoid the error message?
I have a model with a Time field:
namespace SFK\Model {
use SilverStripe\ORM\DataObject;
class Venue extends DataObject {
private static $table_name = 'sfk_venue';
private static $db = array(
'Title' => 'Varchar(100)',
'DefaultStartTime' => 'Time', // <-- This is the problem
'Description' => 'HTMLText',
);
private static $summary_fields = ['Title'];
}
}This model should be managed using ModelAdmin:
use SilverStripe\Admin\ModelAdmin;
class MyAdmin extends ModelAdmin {
private static $managed_models = [
\SFK\Model\Venue::class,
];
private static $url_segment = 'myadmin';
private static $menu_title = 'My Admin';
}When I add or edit a venue in the admin backend, a popup with “Internal Server Error” is displayed. The server response is:
[Warning] IntlDateFormatter::parse(): Date parsing failed
POST /sfk7/admin/myadmin/SFK-Model-Venue/EditForm/field/SFK-Model-Venue/item/1/ItemEditForm/

386 protected function frontendToInternal($time)
387 {
388 if (!$time) {
389 return null;
390 }
391 $fromFormatter = $this->getFrontendFormatter();
392 $toFormatter = $this->getInternalFormatter();
393 $timestamp = $fromFormatter->parse($time);
394
395 // Try to parse time without seconds, since that's a valid HTML5 submission format
396 // See https://html.spec.whatwg.org/multipage/infrastructure.html#times
397 if ($timestamp === false && $this->getHTML5()) {
398 $fromFormatter->setPattern(str_replace(':ss', '', DBTime::ISO_TIME));
399 $timestamp = $fromFormatter->parse($time);
Trace
... (a long trace; I can add it if someone is interested in it)Nevertheless the data is saved in the database. Can anyone help me, how to avoid the internal server error popup? It is not very “user-friendly”. Thanks!
