I solved according Maciej Rogosz recommended: Custom Template Tag

First: I created the folder templatetags inside of my app, after that create a empty ini.py and finally created my custom_tag.py:

from django import template
register = template.Library()

@register.filter(name='split1')
def split1(value, key):
  return value.split(key)[1]

@register.filter(name='split2')
def split2(value, key):
  return value.split(key)[0]

In my tamplate I have to load the template tags

{% load custom_tags %}

And call my custom_tags: split1, split2

{{ instance.mat_code|split1:"|" }}
{{ instance.mat_code|split2:"|" }}

That is it, python + django = Magic

Tks to everyone for your help

Create a custom template tag. They are basically python code which you can execute from inside the html templates (when using defult Django templating engine).

You can read more about them here:
