[Fixed]-Register custom filter in django

24👍

✅

First of all, you haven’t defined register:

To be a valid tag library, the module must contain a module-level
variable named register that is a template.Library instance, in which
all the tags and filters are registered.

Also, I usually decorate the function with register.filter:

from django import template

register = template.Library()

@register.filter
def intcomma(value):
    return value + 1
