Model定义：
class Test(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=128, unique=True, db_index=True) #create_time = models.DateTimeField(auto_now_add=True, db_index=True) #update_time = models.DateTimeField(auto_now=True, db_index=True) create_time = models.DateTimeField(default=timezone.now, db_index=True) update_time = models.DateTimeField(default=timezone.now) description = models.TextField(null=False, blank=True)
datetime转化为时间戳：
from datetime import datetime from django.utils import timezone from django.utils.timezone import utc time.mktime(timezone.now().timetuple())
时间戳转化为datetime：
datetime.utcfromtimestamp(1476321626.0).replace(tzinfo=utc)
