我有以下循环设置,但需要删除最后一项的逗号(它是为cycle2复制一个JSON数组)

{% for product_in_series in series.get_products %}{%spaceless%}
    {% with product_in_series.product as product %}
    {%if not forloop.first%}
            "<img src='{% version product.get_overview 'page_image' %}'>",
    {%endif%}
    {% endwith %}
{%endspaceless%}{% endfor %}

干杯,R
