我有多个字段的django模型,它被映射到MySQL数据库,现在模型中有一个日期时间字段,我想在其中设置分区.

该模型如下所示:

class Packet(models.Model):
    device = models.ForeignKey(Device)
    packet_time = models.DateTimeField(default=timezone.now())
    # Location Details
    signal = models.CharField(max_length=2, default='A')
    lat = models.FloatField(default=None, null=True)
    lat_indicator = models.CharField(max_length=1, default='')
    lng = models.FloatField(default=None, null=True)
    lng_indicator = models.CharField(max_length=1, default='')
    address = models.CharField(max_length=64, default='NA')
    speed = models.FloatField(default=None, null=True)
    orientation = models.FloatField(default=None, null=True)
    #House Keeping Items
    dor = models.DateTimeField(default=timezone.now()) # <= Want to partition this for weekly basis. 
    dirty = models.BooleanField(default=False)

请告诉我如何实现这一目标.
