Jestem nowy w symfony2. Używam liipImagineBundle do zarządzania miniaturą obrazu. Mam klasy encji produktu, która używa wywołań zwrotnych cyklu życia do zarządzania obrazem produktu.Usuń/zaktualizuj buforowany obraz podczas aktualizacji/usuwania rekordu za pomocą liipImagineBundle

generowanie miniatur poprawnie.
Ale nie jestem w stanie znaleźć sposobu na aktualizację/usunięcie obrazu z pamięci podręcznej podczas zmiany oryginalnego obrazu lub usunięcia go za pomocą formularza.
Nie można ponownie uruchomić kodu generacyjnego, gdy ktoś zmieni obraz za pomocą formularza? Jak to zmienić, przesyłając nowy obraz lub coś takiego? –
Mam dwa wymagania: 1) gdy użytkownik usunie produkt w momencie, gdy oryginalny obraz zostanie usunięty i ja również chcę usunąć jego miniaturkę jeśli istnieje 2) gdy obraz aktualizacji produktu użytkownika powinien zostać usunięty, a także jego buforowany obraz miniatura, jeśli istnieje –
