python django查询一周内的数据，一月内的数据，一年内的数据

cur_time= datetime.datetime.now() # 如果数据库保存的是UTC时间,程序不会蹦但是会提示你这不是本地时间  

now_time_utc = datetime.datetime.utcnow()

# 当前天 显示当前日期是本周第几天
day_num = cur_time.isoweekday()
# 计算当前日期所在周一
monday = (cur_time - datetime.timedelta(days=day_num))
# 查询一周内的数据
all_datas = YourModel.objects.filter(time__range=(now_time, monday))

all_datas = YourModel.objects.filter(time__month=now_time.month)

all_datas = YourModel.objects.filter(timeyear=now_time.year)

# 1、gt：大于某个时间
now = datetime.datetime.now()
#前一天
start = now – datetime.timedelta(hours=23, minutes=59, seconds=59)
a=yourobject.objects .filter(youdatetimcolumngt=start)**

# 2、gte：大于等于某个时间：
a=yourobject.objects .filter(youdatetimcolumn__gte=start)

# 3、lt：小于
a=yourobject.objects .filter(youdatetimcolumn__lt=start)

# 4、lte：小于等于
a=yourobject.objects .filter(youdatetimcolumn__lte=start)

# 5、range：查询时间段
start_date = datetime.date(2005, 1, 1)
end_date = datetime.date(2005, 3, 31)
Entry.objects.filter(pub_date__range=(start_date, end_date))

# 6、year：查询某年
Entry.objects.filter(pub_date__year=2005)

# 7、month：查询某月
Entry.objects.filter(pub_date__month=12)

# 8、day：某天
Entry.objects.filter(pub_date__day=3)

# 9、week_day：星期几
Entry.objects.filter(pub_date__week_day=2)

# 10、获取今天的日期，日期格式为yyyy-MM-dd

from django.utils.timezone import now, timedelta
date = now().date() + timedelta(days=-1) # 昨天
date = now().date() + timedelta(days=0) # 今天
date = now().date() + timedelta(days=1) # 明天
