Ho dovuto filtrare un tipo di contenuto contenente le date delle aste in tre gruppi (ora online, in arrivo e pronto per la registrazione). Dato che ciò ha comportato molteplici problemi, ho scritto un plug-in basato su questo articolo: https://www.webomelette.com/creating-custom-views-filter-drupal-8
Fondamentalmente fa tre cose: - Convertire le date nel campo in data e ora locali. - Il filtro ha tre possibili impostazioni 'now online', 'coming' e 'other' - In base alle impostazioni aggiunge le possibili clausole where alla query
Funziona e sembra robusto agli aggiornamenti futuri.
