У меня есть модель комментария на домашней странице, но она не может автоматически определить, в каком сообщении я пишу свой комментарий среди всех сообщений

Question

Итак, ошибка, с которой я сталкиваюсь. ПК не может быть распознан. Потому что на главной странице слишком много постов. Я пытался решить эту проблему, меняя pk на id, меняя модели комментариев многими способами. Но это бесполезно

Реальная причина в том, что я должен перейти к подробному обзору, чтобы страница могла легко обнаружить. О, смотрите, он здесь на пути к этой странице ('post //', PostDetailView.as_view (), name = "post-detail"), так что мы можем сохранить этот комментарий в специальном post.pk. Но я хочу, чтобы все было связано

NameError в / name 'pk' не определено
