twig - 替换for循环中的动态变量

Question

我试图弄清楚如何检索计数并替换下面循环中的“0”

{% for product in products %}

  {{ loop.index0 }} <--- This count too replace "0" designer.0.images
  
  {% for key,value in designer.0.images %}
     <div class="imageprodalign">{{ value }}<br>{{ key }}</div>              
  {% endfor %}

{% endfor %}
