Way to optimize ORM queries to the database with get_queryset()

[zobweyt]

Using Django Debug Toolbar I noticed that the NotificationViewList that displays the list of all notifications loads Django ORM very much and creates a lot of queries to the database.

How can this be optimized? I think it's possible using get_queryset(), but I don't know exactly which object will be displayed in this list and there is no clean way to extend the view, so I can't make select_related() for all situations. Most likely it needs to be executed for GenericForeignKey.

Here is my template override file

<!-- BASE_DIR/templates/notifications/list.html -->
{% extends 'base.html' %}

{% block content %}
<ul class="notifications">
  {% for notice in notifications %}
    {% include 'notifications/notice.html' %}
  {% endfor %}
</ul>
{% endblock content %}

How can I reduce the load on the database and reduce queries?
