Ich musste einen Inhaltstyp mit den Auktionsterminen in drei Gruppen einteilen (jetzt online, in Kürze verfügbar und zur Registrierung bereit). Da es sich um mehrere Themen handelte, habe ich ein Plugin geschrieben, das auf diesem Artikel basiert: https://www.webomelette.com/creating-custom-views-filter-drupal-8
Grundsätzlich gilt Folgendes: - Konvertieren Sie die Daten im Feld in lokales Datum und Uhrzeit. - Der Filter verfügt über drei mögliche Einstellungen: "Jetzt online", "Bevorstehend" und "Andere". - Basierend auf den Einstellungen werden der Abfrage die möglichen Where-Klauseln hinzugefügt
Es funktioniert und scheint robust für zukünftige Updates.
