Django循环–删除最后一个逗号 [英] Django loop – remove last comma

问题描述

我设置了以下循环，但是需要删除最后一项的逗号(这是为cycle2复制JSON数组)

I have the following loop set up, but need to remove the comma on the last item (it's to replicate a JSON array for cycle2)

{% 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

推荐答案

这怎么办?

{% 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' %}'>"
        {%if not forloop.last%},{%endif%}
    {%endif%}
    {% endwith %}
{%endspaceless%}{% endfor %}
