Теперь я вижу, что вы передаете значение pk, используя {% url 'view_profile_with_pk' pk=user.pk %}

На основе ошибки:

 Exception Value: Reverse for 'view_profile_with_pk' with keyword arguments '{'pk': ''}' not found.
  

Значение pk не передается. Я вижу, что вы используете этот URL-адрес в двух местах вашего home.html файла.

Это наводит меня на мысль user , что либо friend объект or не существует в вашем цикле. Проверьте views.py файл, в котором указан ваш домашний маршрут. Убедитесь, что вы отправляете допустимые переменные для обоих users и friends . Убедитесь, что вы используете users , а не user

Редактировать:

В том views.py , который содержит ваш домашний маршрут, вы создаете переменную, вызываемую friends , если пользователь аутентифицирован, friends содержит всех друзей, принадлежащих пользователю. Однако, если пользователь не прошел проверку подлинности, вы присваиваете friends кортежу friends=(1,) . Этот кортеж не будет иметь значения первичного ключа.

Когда URL пытается передать значение pk, оно будет пустым. Попробуйте изменить значение friends на None , если пользователь не аутентифицирован.
