templatetags Directory

Purpose

This directory contains Django custom template tags and filters that extend Django's template system with application-specific functionality. These custom filters provide specialized data processing and formatting capabilities for the parody news generator templates.

Contents

  • __init__.py: Python package initialization file making this directory a Python package
  • custom_filters.py: Custom Django template filters for field access, text truncation, and dictionary formatting

Usage

Template tags and filters are loaded and used in Django templates:

<!-- Load custom filters in templates -->
{% load custom_filters %}

<!-- Use custom filters -->
{{ instance|get_field_value:"field_name" }}
{{ long_text|truncate_chars:100 }}
{{ dictionary_data|dict_to_text_list }}

Available custom filters: - get_field_value: Dynamically access field values from model instances using field name strings - truncate_chars: Truncate text to specified maximum length with ellipsis - dict_to_text_list: Convert dictionary data to formatted text lists for display

Example usage in templates: 

<!-- Dynamic field access -->
{% for field_name in dynamic_fields %}
    <p>{{ object|get_field_value:field_name }}</p>
{% endfor %}

<!-- Text truncation -->
<p>{{ article.content|truncate_chars:150 }}</p>

<!-- Dictionary formatting -->
<pre>{{ metadata|dict_to_text_list }}</pre>
