Humanizing the time difference ( in django )

django.contrib.humanize is a set of Django template filters that adds human touch to data. It provides naturalday filter that formats date to ‘yesterday’, ‘today’ or ‘tomorrow’ when applicable.

A similar requirement which the humanize pacakge does not address is to display time difference with this human touch. so here is a snippet that does so.

from django import template register = template.Library() MOMENT = 120 # duration in seconds within which the time difference # will be rendered as 'a moment ago' @register.filter def naturalTimeDifference(value): """ Finds the difference between the datetime value given and now() and returns appropriate humanize form """ from datetime import datetime if isinstance(value, datetime): delta = datetime.now() - value if delta.days > 6: return value.strftime("%b %d") # May 15 if delta.days > 1: return value.strftime("%A") # Wednesday elif delta.days == 1: return 'yesterday' # yesterday elif delta.seconds > 3600: return str(delta.seconds / 3600 ) + ' hours ago' # 3 hours ago elif delta.seconds > MOMENT: return str(delta.seconds/60) + ' minutes ago' # 29 minutes ago else: return 'a moment ago' # a moment ago return defaultfilters.date(value) else: return str(value)
