一个可能的解决方案是在后端获取每个服务的映像路径，并以某种方式将其添加到上下文中。
例如，在views.py:

images_path = os.path.join(STATIC_URL, 'webapp', 'img')

# ... get services from somewhere

# add the image_paths as an attribute to each service
for service in services:
    image_paths = os.listdir(os.path.join(images_path, service.id))
    setattr(service, 'image_paths', image_paths)

return render(request, 'webapp/index.html', {
    'services': services,
})

然后在index.html中：

# code
{% for service in services %}
    # code
    <div id="imagesCarousel" class="carousel slide" data-bs-ride="carousel">
        <div class="carousel-inner"> 
        {% for image_path in image_paths %}
        <!-- whatever goes here, e.g. <img src="{{image_path}}"> -->
        {% endfor %}
        </div>
    </div>
{% endfor %}
