Create new for loop from for loop in Django

If you look at the piece of code below, you will understand exactly what I want. Enough even if I only get the number of cars that comply with this condition. Or it would be great if we could create a new loop from cars that comply with this condition.

{% for car in cars %}
    {% if car.color == 'white' %}
            create new for loop from white cars
            or
            give me the numbers of white cars
    {% endif %}
{% endfor %}

You can use regroup template tag to group the list of cars by the color and then select the list of cars with white color to iterate over.

{% regroup cars by color as cars_grouped_by_color %}



{% for cars in cars_grouped_by_color %}
  {% if cars.grouper == 'white' %}
    {% for car in cars.list %}
      ...
    {% endfor %}
  {% endif %}
{% endfor %}

Refer regroup documentation for more details.

It is not possible to do it in a template. Modify your ORM query statement.

white_cars = Car.objects.filter(color='white')

And use it in your template with single loop.

{% for car in white_cars %}
    // Your code
{% endfor %}
