获取元素迭代thgrough多种选择领域的Django的指数为环

Question

我MultipleChoiceFieldfield

OPTIONS = (
     ("AUT", "Austria"), 
     ("DEU", "Germany"), 
     ("NLD", "Neitherlands"), 
    ) 

    countries = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(attrs={"name": "select_0","class": "fff"}), 
              choices=OPTIONS) 

我建立我自己的HTML结构这一领域，这被简化代码：

{% for value, text in simple_search_form.countries.field.choices %} 
    {{value}} 
    {{text}} 
{% endfor %} 

怎么办我在这里得到每个元素的索引？ 我需要有

{{value}} 
{text}} 
{{index}} 

Answer 1

如果它在一个for循环，您可以使用

{{ forloop.counter0 }}
