Django как изменить базу данных с помощью кнопки на новом окне и закрыть, обновить главную страницу?

Я создал страницу "Список оповещений". (alert_list.html)

и когда я нажимаю на кнопку, он отображает детальную страницу использует пк в новом окне. (alert_detail.html)

Но у меня есть некоторые проблемы с этим.

То, что я хочу сделать...

1. change Event.event_status value to 0.
2. close new window(detail page)
3. refresh main page(alert list page)

<alert_list.html>

{% for event_alert in event_list %}
                {% if event_alert.event_status == 1 %}
                <div class="col-1 red">
                    <div class="p-3 rounded-2" id="dash_board_patient_alert">
                        <a href="{% url 'Alert Detail' event_alert.event_id %}">{{event_alert.member_id}} {{event_alert.event_type}}</a>
                    </div>
                </div>
                
                {% endif %}
                {% endfor %}
                {{event_alert_activate_count}}
                {{pink_block}}
                {% for _ in pink_block %}
                <div class="col-1 pink">
                    <div class="p-3 rounded-2" id="dash_board_patient_alert">
                        <a href="#"></a>
                    </div>
                </div>
                {% endfor %}

            {% for event_alert in event_list %}
            <form method="POST" class="post-form" action ="{% url 'Alert Update' event_alert.pk %}">
            {% csrf_token %}
