在它变得非常混乱之后，我决定从头开始重新启动我的数据库。所以我删除了数据库，现在尝试用syncdb重新创建它。正如您在下面看到的那样，它正在创建表 wood_management，因为它在木材管理中找不到 wood_uuid，所以它在该表中翻倒了。但是，它还没有进行木材管理，所以我很困惑。

姜戈模型：

class TimberMeasurement(models.Model):
    uuid              = UUIDField(primary_key=True)
    timber            = models.ForeignKey(Timber, db_column='timber_uuid',null=True, blank=True, editable=False)
    measurement_value = models.FloatField(null=True, blank=True)
    measurement_type  = models.IntegerField(null=True, blank=True, choices=MEASUREMENT_TYPE, editable=False)

    class Meta:
        app_label = 'boughtin'
        db_table = 'timber_measurement'
        unique_together = ('timber', 'measurement_value', 'measurement_type')

在运行新的同步数据库之前，似乎需要执行以下操作

#unique_together = ('timber', 'measurement_value', 'measurement_type')
