Re: Total in a django template

[Gath]

Try using custom tags

Create a folder called "templatetags" in your application folder, in
there create two files
 __init__.py
 customtags.py# this will have your custom tags/filters, please
note it can be any name.

Open your customtags.py file and drop the following lines and save.

from django.template import Library

register = Library()

@register.filter
def running_total(fine_list):
return sum(d.get('fine_sum') for d in fine_list

In your template call the customtags file like this

{% load customtags %}

i guess by this time you have a list of dict that you passed from your
view lets say its called "fines"

{% for fine in fines %}
  Display your fine items inside this loop
{% endfor %}

outside the loop call the customtag like this

 {{ fines.list|running_total }} 

It works for me.

Re: Total in a django template

[Knut Ivar Nesheim]

You need to sum the fines before you enter the templates.

This can be done either in your view like this:
total_fines = sum([item.fine for item in items])

Or you can do it in the db using the 'Sum' aggregate, see
http://docs.djangoproject.com/en/dev/ref/models/querysets/#sum

Re: Total in a django template

Hello, 
    I am not sure if this is what you are looking for but you can use a 
forloop.counter (index to 1) or a forloop.counter0 (index at 0) from within the 
template {% for loop %}

Hi,
In a django template I have a for loop that display (item, fine). I
would like to compute the total fine value at the end of the for loop.
Is it possible to compute the total in the template? How can I do it
