Шаблон не отображается в Django (NoReverseMatch)

Я не совсем уверен, в чем проблема, но у меня в проекте есть код, который при выборе даты выводит таблицу с именами студентов в классе, но Django продолжает говорить мне, что нет NoReverseMatch. Я дважды проверил и все в порядке, но не уверен, почему он не работает.

ПОКАЗАНА ОШИБКА
