问题描述:

Is it possible to access the forloop.counter for the outermost for loop in the following template in Django:

{% for outerItem in outerItems %}

{% for item in items%}

<div>{{ forloop.counter }}.&nbsp;{{ item }}</div>

{% endfor %}

{% endfor %}

forloop.counter returns the innermost for loop's counter in the above example

网友答案:

You can use forloop.parentloop to get to the outer forloop, so in your case {{forloop.parentloop.counter}}.

网友答案:

you can also use with

Caches a complex variable under a simpler name. This is useful when accessing an “expensive” method (e.g., one that hits the database) multiple times.

{% for outerItem in outerItems %}
  {% with forloop.counter as outer_counter %}
    {% for item in items%}
        <div>{{ outer_counter }}.&nbsp;{{ item }}</div>
    {% endfor %}
  {% endwith %}
{% endfor %}

if using high version of Django you could use

{% with outer_counter = forloop.counter %}

I've checked, Django 1.4.x - Django 1.9.x support the two methods.

this is more clear when have many for loops
