我想了解如何从DateTimeField
中提取年、月、日、小时和分钟。
我想要提取信息的DateTimeField名为'redemption_date',模型的代码如下:
from django.db import models
from datetime import datetime, timedelta
class Code(models.Model):
id = models.AutoField(primary_key=True)
code_key = models.CharField(max_length=20,unique=True)
redemption_date = models.DateTimeField(null=True, blank=True)
user = models.ForeignKey(User, blank=True, null=True)
# ...
def is_expired(self):
expired_date = datetime.now() - timedelta( days=2 )
my_redemtion_date = self.redemption_date
if self.redemption_date is None:
return False
if my_redemtion_date < expired_date:
return True
else:
return False
