Question

我在模板中使用{{ prospect.date_1 }} - ({{ prospect.date_1|timesince }} ago)以获取自该日期起的时间。

关键是，date_1是date而不是datetime，所以当我应用过滤器时，它告诉我像

July 18, 2014 - (11 hours, 39 minutes ago)

预期产出

July 18, 2014 - (0 days ago)

Answer 1

@register.filter(expects_localtime=True)
def days_since(value, arg=None):
    try:
        tzinfo = getattr(value, 'tzinfo', None)
        value = date(value.year, value.month, value.day)
    except AttributeError:
        # Passed value wasn't a date object
        return value
    except ValueError:
        # Date arguments out of range
        return value
    today = datetime.now(tzinfo).date()
    delta = value - today
    if abs(delta.days) == 1:
        day_str = _("day")
    else:
        day_str = _("days")

    if delta.days < 1:
        fa_str = _("ago")
    else:
        fa_str = _("from now")

    return "%s %s %s" % (abs(delta.days), day_str, fa_str)

结果

>>> days_since(datetime.now())
'0 days ago'
>>> days_since(date(2013, 5, 12))
'432 days ago'
>>> days_since(date(2014, 12, 12))
'147 days from now'
>>> days_since(date(2014, 7, 19))
'1 day from now'

Answer 2

@Jack，你有没有尝试使用内置的python：

访问：https://docs.python.org/2/library/datetime.html#datetime.datetime.day

如果这可能会有所帮助：

https://docs.djangoproject.com/en/1.6/ref/contrib/humanize/#naturaltime

编辑：

from datetime import date
from datetime import datetime
d = date.today()
datetime.combine(d, datetime.min.time())

Django内置的timesince过滤器只显示Days
