[英]Error testing dates in Django models
我正在努力測試一些Django模型,您可以在此處查看相關代碼:
楷模:
class Check(models.Model):
date = models.DateTimeField(auto_now_add=True)
...
正在測試的功能:
def get_today_records(model):
today = datetime.today()
today_records = model.objects.filter(
date__year=today.year,
date__month=today.month,
date__day=today.day)
return today_records
測試文件:
def setUp(self):
self.today_check = models.Check.objects.create(
...
date=datetime.today())
def test_get_today_records(self):
past_check = self.today_check
past_check.date = datetime(2012, 1, 1)
past_check.save()
today_records = get_today_records(models.Check)
self.assertTrue(self.today_check in today_records,
'get_today_records not returning today records')
self.assertTrue(past_check not in today_records,
'get_today_records returnig older records')
錯誤:
======================================================================
Traceback (most recent call last):

我在外殼上進行了一些手動測試,並應用了相同的過濾條件,它返回了我兩分鍾前剛剛創建的記錄。 我肯定還有另一件事想念。
注意:我進行這項測試的日期是2013/06/1
提前致謝
在測試函數中, past_check = self.today_check
不會像您期望的那樣創建新記錄,而是修改數據庫中的現有記錄。
當執行past_check.save()
,它將使用過去的更新日期來更新數據庫中的單個記錄。
您可能在測試中想要這樣的東西:
past_check = models.Check.objects.create(date=datetime(2012, 1, 1))
代替:
past_check = self.today_check
past_check.date = datetime(2012, 1, 1)
past_check.save()
