Customizing Django Templates conjugate_is templatetag

Not sure what is wrong

code_challenges/templatetags/fairy_extras.py 
from django import template

register = template.Library()

@register.simple_tag
def conjugate_is(num):
    if num == 1:
        return 'is'
    else:
        return 'are'
code_challenges/templates/code_challenges/list.html 
{% load fairy_extras %}

 There {{ conjugate_is num=num_elf }} {{ num_elf }} el{{ num_elf|pluralize:"f,ves" }}.

conjugate_is is a tag so it needs to be called with {% and %}. The {{ represents when you want to print out a value, not use a tag.

Thank you :) Do you know if there will ever be a course on payments with Django?

I'm not currently planning a "Payments in Django" course but you're not the first to ask about it so maybe I should! If so, it'll be after the new year.

I think it would be a very useful course that would interest a lot of people, so hopefully there will be one :)
