Custom template tags - instance.templatetag

[Jan Gregorczyk]

Hi! How to change my template tag?

from django import template

register = template.Library()

@register.simple_tag

def votes_up_exists(answer, user_id):

pass

how I use it - {% votes_up_exists answer request.user.id %}

how I would like to use it - {% answer.votes_up_exists user_id %}

Hi Jan,

You can't do it like that. A templatetag is a simple function that is handled in a special way by the django templating language.

See here for an explanation:

Sorry - I posted that without a link?

This is by design - and you should always try to simplify what you are doing in django templates.
