Django xadmin 如何删除models.OneToOn

场景描述

采用OneToOneField 生成Users对象，当我们需要删除Users对象时，我希望联动删除User账户。

解决方案

class Users(models.Model):
    user = models.OneToOneField(User,verbose_name=u'用户名',on_delete=models.DO_NOTHING)
    user_name=models.CharField(_(u'人员姓名'),max_length=30)
    user_type=models.ManyToManyField(UsersType,verbose_name=u'人员类型')
    user_department=models.ForeignKey(Department, verbose_name=u'单位信息',on_delete=models.DO_NOTHING)
    user_mobilephone=models.CharField(_(u'手机号码'), max_length=25,null=True,blank=True)

删除

    def delete_models(self, queryset):
        userList=[]
        for obj in queryset:
            UserWidget.objects.filter(user=obj.user).delete()
            UserSettings.objects.filter(user=obj.user).delete()
            userList.append(obj.user)
            

        super(UsersAdmin, self).delete_models(queryset)
        for item in userList:
            item.delete()
