In the FILTERS section of the utility_tags.py template library in the utils app, let's add the humanize_url filter and register it, as shown in the following code:

# utils/templatetags/utility_tags.py
import re

from django import template

register = template.Library()


"""FILTERS"""

@register.filter
def humanize_url(url, letter_count):
    """
    Returns a shortened human-readable URL
    """
    letter_count = int(letter_count)
    re_start = re.compile(r"^https?://")
    re_end = re.compile(r"/$")
    url = re_end.sub("", re_start.sub("", url))
    if len(url) > letter_count:
        url = f"{url[:letter_count - 1]}..."
    return url
