Time模塊 - strptime Django的驗證錯誤

Question

我寫了一個函數返回當前財年的日期：在我的代碼

def get_fiscal_year(start_month=7): 
    now = datetime.datetime.now() 
    if now.month >= start_month: 
     return [time.strptime(str(now.year) + '-07-01', '%Y-%m-%d'), time.strptime(str(now.year + 1) + '-06-30', '%Y-%m-%d')] 
    return [time.strptime(str(now.year - 1) + '-07-01', '%Y-%m-%d'), time.strptime(str(now.year) + '-06-30', '%Y-%m-%d')] 

然後我使用它，如下所示：

dates = get_fiscal_year() 
    start_date = dates[0] 
    end_date = dates[1] 
    model = DevelopmentAssessment.objects.filter(status_id__in=[8, 7, 10], decision_date__range=[start_date, end_date]) 

然而，它拋出的錯誤：

[u"'time.struct_time(tm_year=2012, tm_mon=7, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=6, tm_yday=183, tm_isdst=-1)' value has an invalid date format. It must be in YYYY-MM-DD format."] 

據我可以告訴它的格式，任何想法是怎麼回事？

乾杯， 本

從你的函數get_fiscal_year而__range()需要date類型的對象要返回time.struct_time對象的字典。

我建議修改你的函數返回date對象作爲

def get_fiscal_year(start_month=7): 
now = datetime.datetime.now() 
if now.month >= start_month: 
    return [datetime.date(year=now.year, month=7, day=1), 
      datetime.date(year=now.year + 1, month=6, day=30)] 
return [datetime.date(year=now.year-1, month=7, day=1), 
      datetime.date(year=now.year, month=6, day=30)]
