Реверс для 'update' с ключевыми аргументами '{'id': ''}'' не найден. Проверен 1 шаблон(ы): ['update/(?P<id>[0-9]+)/\\Z']

Я пытаюсь обновить модель ActiveMember, которая имеет поле OneToOneField с членами. Я сталкиваюсь с этой ошибкой.

Reverse for 'update' with keyword arguments '{'id': ''}' not found. 1 pattern(s) tried: ['update/(?P<id>[0-9]+)/\\Z']

Я новичок в django и не уверен, как решить эту проблему.

Кроме того, я пытаюсь сделать систему управления тренажерным залом, где я могу добавлять новых членов и активировать их членство, а также просматривать активных и неактивных членов (см. фото ниже для того, что у меня есть сейчас). Мне бы хотелось получить некоторые рекомендации, если я двигаюсь в правильном направлении. После этого я смогу решить свою текущую проблему. Я хотел бы преодолеть большое препятствие. Я бы хотел, чтобы после истечения срока членства статус членов менялся на неактивный (автоматически), чтобы я мог видеть их в разделе неактивных членов.

def update(request, id):
    member = ActiveMember.objects.get(pk=id)

    if request.method == 'POST':
        form = ActiveMemberForm(request.POST, instance=member)
        if form.is_valid():
            # update the existing `Band` in the database
            form.save()
            # redirect to the detail page of the `Band` we just updated
            return render(request, 'members/update.html', {
                'form': form,
                'success': True,
            })
    else:
        form = ActiveMemberForm(instance=member)

    return render(request, 'members/update.html', {
        'form': form, 
        'member': member,
        })
