Re: template tag help please?

Hi,

You don't need the {{}} when sending a variable to the template tag - try removing them.

I am so rusty I'm having trouble writing a simple_tag

 

In the template

 

{% for b in list %}

{% load get_cost %}{% do_cost {{ b.name }} avn avd %}

 

Also tried (per docs) {% do_cost name={{ b.name }} avn=avn avd=avd %}

I definitely have values in the template passed from the view for avn and avd and of course b.name

 

Tag

from django import template

from django.conf import settings

from django.utils.html import escape

from band.models import Data

 

register = template.Library()

 

@register.simple_tag

def do_cost( name, avn, avd, *args, **kwargs ):

    avn = kwargs['avn']

    avd = kwargs['avd']

    name = kwargs['name']

 

    val = Data.objects.filter(property=name).filter(date_period=date)

    return val

 

I just keep getting do_cost takes 3 arguments

*** I know I want it to take 3 arguments!!!!***

Is it telling me that I can't use {{ b.name }} as an arg?
