多对多创建的时候如何取消掉被关联表的ON DUPLICATE KEY UPDATE ？

[liyuan1125]

Your Question

type (
	Languages struct {
		ID   uint   `json:"id"`
		Name string `json:"name"`
	}

	User struct {
		ID        uint         `json:"id"`
		Name      string       `json:"name"`
		Languages []*Languages `json:"languages"`
	}
)

user := &User{Name: "jinzhu", Languages: []*Languages{
		{ID:1},
		{ID:2},
	}}

	db.Create(user)
	db.Session(&gorm.Session{FullSaveAssociations: false}).Create(user)

以上会多一句：

INSERT INTO `languages ` (`name`,`id`) VALUES ('',1),('',2) ON DUPLICATE KEY UPDATE `id`=`id`

不能跳过吗？
