Всем привет. Изучаю джанго на одной из платформ айти, делаю проект по мини-соц. сети. Логика такая, пользователь регистрируется, пишет посты, оставляет комментарии на других постах и в случае чего редактирует или удаляет их. Есть соответствующие тесты после написания проекта. При проверке выдает ошибку:
на сайте выглядит все вроде бы окей:
шаблон тоже корректный.
Судя по описанию ошибки копать надо якобы в CBV удаления комментария. НО, раз 10 проверял, перепроверял, менял, подставлял другой код, но результат один. Соответсвенно, делаю вывод, что ошибка в других CBV, пытался искать пробовать разные вариации, но безрезультатно. Если есть более опытные, кто мог бы проанализировать и выявить проблемку, буду благодарен.
