beego 多对多查询报错

本人最近在学习beego框架，正用一个博客练手，文章这部分遇到了一些问题，我google了半天，发现我的语法好像没什么问题，但是就是报错，希望各位大佬给看一看多谢!

一篇文章可以有多个label,而一个label也可以被多篇文章使用，所以使用了多对多的模型关系
下面是文章Article模型

type Article struct {

    Id          int       `form:"-"`
    //这个是标签
    Label       []*Label  `orm:"rel(m2m);rel_through(blog/models.Articlelabel)"`

}

这个是标签Label模型

type Label struct {
    Id int `form:"-"`
    Title string `form:"title"`
    //这个是文章关联
    Article []*Article `orm:"reverse(many)"`
}

这个是关联模型Articlelabel

type Articlelabel struct {
    Id int 
    Article_id *Article `orm:"rel(fk)"`
    Label_id *Label `orm:"rel(fk)"`
}

查询的代码

var list []Article

    o := orm.NewOrm()
    _, err := o.QueryTable("article").RelatedSel().Limit(10).All(&list)
    if err != nil {
        return []Article{}, err
    }

    for _,v := range list {
        //这里打印 V是可以打印出来的
        //加上这句就报错
        o.LoadRelated(v, "Label")
    }
    return list, nil

加上这句o.LoadRelated(v, "Label")就报错,不知道是我哪里出了问题
报错如下

查询了网上的文章大多是一个文章各种抄，没办法只能来提问了。提前感谢
