详解Django将秒转换为xx天xx时xx分

Django将秒转换为xx天xx时xx分，具体代码如下所示：

from django.utils.translation import ngettext_lazy as _n

def humanize_seconds(secs):
  a_day = 86400
  an_hour = 3600
  a_minute = 60
  timetot = ''
  total_secs = secs
  if secs > a_day: # 60sec * 60min * 24hrs
    days = int(secs // a_day)
    # timetot += "{} {}".format(int(days),_('days'))
    timetot += _n('%(num)s day','%(num)s days',days) % {'num': days}
    secs = secs - days * a_day

  if secs > an_hour:
    hrs = int(secs // an_hour)
    # timetot += " {} {}".format(int(hrs),_('hours'))
    timetot += ' '
    timetot += _n('%(num)s hour','%(num)s hours',hrs) % {'num': hrs}
    secs = secs - hrs * an_hour

  if secs > a_minute and total_secs < a_day:
    mins = int(secs // a_minute)
    timetot += ' '
    timetot += _n('%(num)s minute','%(num)s minutes',mins) % {'num': mins}
    secs = secs - mins * a_minute

  if secs > 0 and total_secs < an_hour:
    secs = int(secs)
    timetot += ' '
    timetot += _n('%(num)s second','%(num)s seconds',secs) % {'num': secs}
  return timetot

if __name__ == "__main__":
  print(humanize_seconds(360200))

知识点扩展：django 将model转换为字典

from django.forms.models import model_to_dict
from projects.models import ProjectInformation

site = ProjectInformation.objects.get(id=6)
dict = model_to_dict(site)
dict
{'CRFmethod': '','EDCprovider': '','acceptancenum': '','add_time': datetime.datetime(2017,4,20,8,42,751202,tzinfo=<UTC>),'begindate': None,'clinicalassis': '','clinicalnum': '','created_by': '','created_date': None,'enddate': None,'ethicsreviewdate': None,'ethicsreviewpers': '','ethicsreviewres': '','ethicsreviewunit': '','id': 6,'isimport': None,'leaderunit': None,'localcases': None,'medicalequipment': '','mequipmenttype': '','multicenter': '','plannum': '','proenname': '爱上地方','proname': '打士大夫','prostatus': '','prosummary': '','protype': '打是否','regstudy': '是','reportdate': None,'reportnum': '','reportversion': '','researchdesign': '','researchtype': '','responsible': '','studytype': '器械类','telephonenum': None,'totalcases': None,'treatmenttype': None,'unitnum': None}
