Template Tag with Arguments - Practical Implementation

# templatetags/custom_tags.py
from django import template
register = template.Library()

@register.simple_tag
def format_currency(amount, currency='USD'):
    return f'{currency} {amount:.2f}'

# template.html
{% load custom_tags %}
{% format_currency 99.5 %}
{% format_currency 150.75 'INR' %}

  1. Simple tags can only accept the value being processed, not additional arguments.

  2. Simple tags accept multiple arguments separated by spaces and support default parameter values.

  3. Arguments must be quoted strings; numeric values are not supported in template tags.

  4. The output of a simple tag must be assigned to a variable using {% as variable_name %} syntax.

Show answer & explanation

Correct answer

Simple tags accept multiple arguments separated by spaces and support default parameter values.

Explanation

Simple tags using @register.simple_tag can accept multiple arguments and are called with space-separated values. Arguments can have default values. The output is inserted directly into the template where the tag is used.
