import datatime date = datetime.datetime.now()

当天：

newdate = datetime.datetime.now() condtions = {‘datadate’: newdate}

昨天：

newdate = date + datetime.timedelta(days=-1) condtions = {‘datadate’: newdate}

本周初：

newdate = now - datetime.timedelta(days=now.weekday()) condtions = {‘datadate’: newdate}

本周末：

newdate = now + datetime.timedelta(days=6 - now.weekday()) condtions = {‘datadate’: newdate}

上周初：

newdate = now - datetime.timedelta(days=now.weekday() + 7) condtions = {‘datadate’: newdate}

上周末：

newdate = now - datetime.timedelta(days=now.weekday() + 1) condtions = {‘datadate’: newdate}

月初：

newdate = date.replace(day=1) condtions = {‘datadate’: newdate}

月末：

year = date.year month = date.month a, b = calendar.monthrange(year, month) 　　　　　　　　　　# a,b——weekday的第一天是星期几（0-6对应星期一到星期天）和这个月的所有天数 newdate = datetime.datetime(year=year, month=month, day=b) # 构造本月月末datetime condtions = {‘datadate’: newdate}

上月初：

date_now = date.replace(day=1) date_now = date_now + datetime.timedelta(days=-1) newdate = datetime.datetime(date_now.year, date_now.month, 1) condtions = {‘datadate’: newdate}

上月末：

date_now = date.replace(day=1) newdate = date_now + datetime.timedelta(days=-1) condtions = {‘datadate’: newdate}

年初：

newdate = date.replace(month=1, day=1) condtions = {‘datadate’: newdate}

年末：

newdate = date.replace(month=12, day=31) condtions = {‘datadate’: newdate}

去年初：

newdate = date.replace(month=1, day=1) newdate = newdate + datetime.timedelta(days=-1) newdate = datetime.datetime(newdate.year, 1, 1) condtions = {‘datadate’: newdate}

去年末：

newdate = date.replace(month=1, day=1) newdate = newdate + datetime.timedelta(days=-1) condtions = {‘datadate’: newdate}

季初：

month = (date.month - 1) - (date.month - 1) % 3 + 1 newdate = datetime.datetime(date.year, month, 1) condtions = {‘datadate’: newdate}

季末：

month = (date.month - 1) - (date.month - 1) % 3 + 1 if month == 10: 　　newdate = datetime.datetime(date.year + 1, 1, 1) + datetime.timedelta(days=-1) else: 　　newdate = datetime.datetime(date.year, month + 3, 1) + datetime.timedelta(days=-1) condtions = {‘datadate’: newdate}

上季初：

month = (date.month - 1) - (date.month - 1) % 3 + 1 newdate = datetime.datetime(date.year, month, 1) newdate = newdate + datetime.timedelta(days=-1) newdate = datetime.datetime(newdate.year, newdate.month - 2, 1) condtions = {‘datadate’: newdate}

上季末：

month = (date.month - 1) - (date.month - 1) % 3 + 1 # 10 newdate = datetime.datetime(date.year, month, 1) newdate = newdate + datetime.timedelta(days=-1) condtions = {‘datadate’: newdate}

半年初：

month = (date.month - 1) - (date.month - 1) % 6 + 1 newdate = datetime.datetime(date.year, month, 1) condtions = {‘datadate’: newdate}

半年末：

month = (date.month - 1) - (date.month - 1) % 6 + 1 if month == 7: 　　newdate = datetime.datetime(date.year + 1, 1, 1) + datetime.timedelta(days=-1) else: 　　newdate = datetime.datetime(date.year, month + 6, 1) + datetime.timedelta(days=-1) condtions = {‘datadate’: newdate}

上个半年初：

month = (date.month - 1) - (date.month - 1) % 6 + 1 newdate = datetime.datetime(date.year, month, 1) newdate = newdate + datetime.timedelta(days=-1) newdate = datetime.datetime(newdate.year, newdate.month - 5, 1) condtions = {‘datadate’: newdate}

上个半年末：

month = (date.month - 1) - (date.month - 1) % 6 + 1 newdate = datetime.datetime(date.year, month, 1) newdate = newdate + datetime.timedelta(days=-1) condtions = {‘datadate’: newdate}

月平均值：

ms_newdate = date.replace(day=1) me_newdate = date new_date = (ms_newdate, me_newdate)

季平均值：

month = (date.month - 1) - (date.month - 1) % 3 + 1 ss_newdate = datetime.datetime(date.year, month, 1) se_newdate = date new_date = (ss_newdate, se_newdate)

半年平均值：

month = (date.month - 1) - (date.month - 1) % 6 + 1 hs_newdate = datetime.datetime(date.year, month, 1) he_newdate = date new_date = (hs_newdate, he_newdate)

年均值：

ys_newdate = date.replace(month=1, day=1) ye_newdate = date new_date = (ys_newdate, ye_newdate)

if condtions: 　　query_res = Entry.objects.filter(**condtions).filter().exclude() if new_date: 　　query_res = Entry.objects.filter(datadate__range=new_date).filter().exclude()
