multiplication in django template without using manually created template tag

Question

I want to achieve multiplication operation in django template. For example I have the values, price=10.50 quantity=3

With the help of this link

Answer 1

There are 2 approaches:

• Computing the values inside the view and pass them to the template (recommended in my opinion)
• Using template filters

In the manner of the add filter, you could always create your own multiply filter, creating your own custom filter:

from django import template

register = template.Library()

@register.filter
def multiply(value, arg):
    return value * arg

Then in your template, something like that should work.

{{ quantity | multiply:price }}

This is not tested, and I never did this as - again - I find neater to compute datas inside the views and render only with the templates.
