How can I create custom template filters in Django?

To create a custom template filter in Django, you need to define a function and register it using the @register.filter decorator.

Can you show me an example of a custom filter?

Sure! Here's a simple example:

from django import template

register = template.Library()

@register.filter
def add_suffix(value, suffix):
    return f'{value}{suffix}'

How do I use this filter in my template?

You can use the filter in your template like this:

{{ my_variable|add_suffix:"_suffix" }}

What if I want to pass multiple arguments to the filter?

You can use a single argument and split it inside the filter function. For example, you can pass a string with a delimiter.
