Есть ли способ использовать условные операторы IF в тегах сжатия Django Compressor?

Есть ли способ использовать условный оператор из тегов {% compress %} в шаблоне Django, который использует Django Компрессор?

Я пробовал, но выдает ошибку. Вот пример того, что я устал:

{% compress js %}
    <script src="{{ STATIC_URL }}js/example-1.js"></script>
    <script src="{{ STATIC_URL }}js/example-2.js"></script>
    {% if settings.EXAMPLE %}
    <script src="{{ STATIC_URL }}js/example-3.js"></script>
    {% endif %}
{% endcompress %}

И это ошибка, которую я получаю:

Обратите внимание, что я использую Django Compressor версии 1.4.

Ни один из примеров использования в документации не содержит условных выражений, а < a href="https://github.com/django-compressor/django-compressor/blob/develop/compressor/templatetags/compress.py" rel="nofollow">обзор кода для тега шаблона compress предполагает, что это потому, что это, вероятно, невозможно.

Вместо этого рассмотрите возможность использования двух отдельных блоков compress:

{% compress js %}
    <script src="{{ STATIC_URL }}js/example-1.js"></script>
    <script src="{{ STATIC_URL }}js/example-2.js"></script>
{% endcompress %}
{% if settings.EXAMPLE %}
    {% compress js %}
        <script src="{{ STATIC_URL }}js/example-3.js"></script>
    {% endcompress %}
{% endif %}
