How to display "x days ago" type time using Humanize in Django template?

Django has a built-in template filter timesince that offers the same output you mentioned above. The following filter just strips the second part after the comma:

from datetime import datetime, timedelta
from django import template
from django.utils.timesince import timesince

register = template.Library()

@register.filter
def age(value):
    now = datetime.now()
    try:
        difference = now - value
    except:
        return value

    if difference <= timedelta(minutes=1):
        return 'just now'
    return '%(time)s ago' % {'time': timesince(value).split(', ')[0]}

You should duplicate your django.contrib.humanize.templatetags.humanize.py to myapp.templatetags.myhumanize and modify it to your needs. (I can't find the actual line that returns "x days, y hours ago". Which version of django/humanize are you using?)

There is naturaltime in modern django.

Given now is 17 Feb 2007 16:30:00.

It changes 16 Feb 2007 13:31:29 to 1 day, 2 hours ago.

{# some_template.html #}
{% load humanize %}
{{ past_time | naturaltime }}
