Beego orm - 关系不起作用

Question

在以下模型中：

package models

import "github.com/astaxie/beego/orm"

type Movie struct {
    Id      int    `orm:"pk; auto; column(id)"; form: "-"`
    Title   string `orm:"unique; column(title)"; form: "title, text, title:`
    Plot    string `orm:"column(plot)"; form: "plot, text, plot:"`
    ImdbID  string `orm:"column(imdb_id)"; form: "imdb_id, text, imdb_id:"`
    Actors  string `orm:"column(actors)"; form: "actors, text, actors:"`
    Runtime string `orm:"column(runtime)"; form: "runtime, text, runtime:"`
    Year    string `orm:"column(year)"; form: "year, text, year:"`
    Genre   *Genre `orm:"rel(fk); on_delete(do_nothing)"`
    Cover   string `orm:"column(cover)"; form: "cover, text, cover:"`
    Status  int    `orm:"column(status)"; form: "status, int, status:"`
}

func (a *Movie) TableName() string {
    return "app_movie"
}

func init() {
    orm.RegisterModel(new(Movie))
}

我想参考：流派模型，它看起来像：

package models

import "github.com/astaxie/beego/orm"

type Genre struct {
    Id     int    `orm:"pk; auto; column(id)"; form: "-"`
    Title  string `orm:"unique; column(title)"; form: "title, text, title:`
    Status int    `orm:"column(status)"; form: "status, int, status:"`
}

func (a *Genre) TableName() string {
    return "app_genre"
}

func init() {
    orm.RegisterModel(new(Genre))
}

有关信息，它转到带有数据的 sqlite 数据库（首先是数据库）。

在控制器中，我遍历电影列表并打印出：movie.Genre.Title 但它是空的。如果我在 movie.Genre 上观看，我会得到：{3 0}

如何获得标题和ID？或者。我做错了什么？

感谢您的帮助！

Answer 1

num, err := qs
    .Limit(4)
    .Filter("status", true)
    .RelatedSel()
    .Exclude("useritem__userid", 1)
    .OrderBy("-id")
    .All(&movies)

all works fine. :) .RelatedSel()
