Weniger Code ist besser
Niemals Code duplizieren
Ansicht sollte nur Präsentationslogik enthalten, keine Geschäftslogik
Halten Sie die Ansichtslogik klar und einfach.
Verwenden Sie CBVs nicht als Fehlerbehandler für 403, 404, 500.
Behalten Sie den Mix bei einfach und klar
Die von Django selbst bereitgestellte Ansicht befindet sich immer ganz rechts
Mixin befindet sich wiederum auf der linken Seite der obigen Ansicht
Mixin erbt immer vom Objekttyp von Python
