Я пытаюсь создать социальную сеть с помощью django. Все работало отлично. затем я изменил некоторый код в двух представлениях. один в представлении post like_unlike_post и представлении сведений о профиле. Я добавил SingleObjectMixin и formviewe с подробным представлением, чтобы люди могли ставить лайки и комментировать сообщения при посещении профиля других пользователей. после этого я замечаю, что эта ошибка возникает каждый раз, когда я пытаюсь войти в систему или что-то обновить. Я понятия не имею, что вызывает эту ошибку. Кто-нибудь может мне помочь с этим. вот сведения о моем профиле и представление обновлений

И это мое представление post, которое содержит представление post и комментариев, а также представление like в отличие от view

Итак, я использовал эластичный поиск для своего проекта, и я был причиной возникновения этой проблемы. Я узнаю об этом при попытке создать другую форму командной строки суперпользователя. Для решения этой проблемы мне пришлось остановить elasticsearch и запустить его снова
