Multiply in django template

Question

I am looping through cart-items, and want to multiply quantity with unit-price like this:

{% for cart_item in cart.cartitem_set.all %}
{{cart_item.quantity}}         


        

Answer 1

You can use widthratio builtin filter for multiplication and division.

To compute A*B: {% widthratio A 1 B %}

To compute A/B: {% widthratio A B 1 %}
