У меня проблема с настройкой первичного ключа для представления списка

Question

Я получаю сообщение об ошибке: - Обратный для 'grievant_complaint_list' с аргументами ключевого слова '{' pk ':' '}' не найден. Попробован 1 шаблон (ов): ['grievant_complaint_list / (? P [0-9] +) / $']

Я пытаюсь предоставить список жалоб, опубликованных конкретным пользователем, на основе пользователявошел в систему, но возникли проблемы с предоставлением первичного ключа. PS Я новичок в django
