# 级联删除，如果部门删除了 该条记录同时删除
# department = models.ForeignKey(to="Department",to_field="id",on_delete=models.CASCADE,verbose_name='部门id')
# to：与某个表关联 to_field：与表中那一列又关联 如果部门删除 部门ID 制空
department = models.ForeignKey(to="Department", to_field="id", null=True, blank=True, on_delete=models.SET_NULL,
verbose_name='部门id')
