here is my filter:
from django import template
import datetime
register = template.Library()
@register.filter
def mytimeiff(timestamp = None):
"""
Returns a humanized string representing time difference
between now() and the input timestamp.
The output rounds up to days, hours, minutes, or seconds.
4 days 5 hours returns '4 days'
0 days 4 hours 3 minutes returns '4 hours', etc...
"""
timeDiff = datetime.datetime.now() - timestamp
days = timeDiff.days
hours = timeDiff.seconds/3600
minutes = timeDiff.seconds%3600/60
seconds = timeDiff.seconds%3600%60
str = ""
tStr = ""
if days > 0:
if days == 1: tStr = "day"
else: tStr = "days"
str = str + "%s %s" %(days, tStr)
return str
elif hours > 0:
if hours == 1: tStr = "hour"
else: tStr = "hours"
str = str + "%s %s" %(hours, tStr)
return str
elif minutes > 0:
if minutes == 1:tStr = "分钟"
else: tStr = "分钟"
str = str + "%s %s" %(minutes, tStr)
return str
elif seconds > 0:
if seconds == 1:tStr = "秒"
else: tStr = "秒"
str = str + "%s %s" %(seconds, tStr)
return str
else:
return None
