关于数据库的切换问题（新手求指教）

models.go中（由默认库切换到Logdb库)

func GiftList(params *GiftQueryParam) ([]*Gift, int64) {
    o := orm.NewOrm()
    o.Using("Logdb")
    query := o.QueryTable(GiftTBName())
    data := make([]*Gift, 0)
    //默认排序
    sortorder := "ID"
    switch params.Sort {
    case "ID":
        sortorder = "ID"
    }
    if params.Order == "desc" {
        sortorder = "-" + sortorder
    }
    query = query.Filter("creatname__istartswith", params.CreatNameLike)
    total, _ := query.Count()
    query.OrderBy(sortorder).Limit(params.Limit, params.Offset).All(&data)
    return data, total
}

在initDatabases里边也配置了Logdb：

    case "mysql":
        dbCharset := beego.AppConfig.String(dbType + "::db_charset")
        orm.RegisterDataBase(dbAlias, dbType, dbUser+":"+dbPwd+"@tcp("+dbHost+":"+
            dbPort+")/"+dbName+"?charset="+dbCharset, 30)
        orm.RegisterDataBase("Logdb", "mysql", beego.AppConfig.String(dbType+"::Logdb"))
    }

当我执行是出现：

user: table name: gift_score_log not exists

还是使用的我的default库 如何才能切换过去,跪谢各位大神给个栗子
