I would like to suggest installing django-mathfilters.
Then you can simply use the abs filter like this:
{% for balance in balances %}
{{ balance.amount|abs }}
{% endfor %}

If you don’t want/can’t install django-mathfilters
You can make a custom filter quite easily:
from django import template
register = template.Library()
@register.filter(name='abs')
def abs_filter(value):
return abs(value)

This works without adding django-mathfilters but it’s not a very good practice.
{% if balance.amount < 0 %}
{% widthratio balance.amount 1 -1 %}
{% else %}
{{ balance.amount }}
{% endif %}
Widthratio is meant for creating bar charts but can be used for multiplication
- I get an error when return a queryset objects: Cannot resolve expression type, unknown output_field
- Django- getting a list of foreign key objects
