Coder moins c'est mieux
Ne jamais dupliquer le code
La vue ne doit contenir que la logique de présentation, pas la logique métier
Gardez la logique d'affichage claire et simple
N'utilisez pas de CBV comme gestionnaires d'erreurs pour 403, 404, 500
Gardez le mixin simple et clair
La vue fournie par Django lui-même est toujours à l'extrême droite
