golang该如何循环 多层结构体

一：首先贴代码（你们大概看看就行，在看看后面的前端页面展示数据 你们就能理解 结构体嵌套的案例）

package model

import (
	"fmt"
	"time"
)

type Find struct {
	Article       []Article
	SelectArticle []SelectArticle
	RecoArticle   []SelectArticle
	SelectLabel   []SelectLabel
	IndexAbout    SiteInfo
	IndexContact  SiteInfo
}

type Article struct {
	Id          int       `gorm:"column:id"`
	Title       string    `gorm:"column:title"`
	Auth        string    `gorm:"column:auth"`
	Image       string    `gorm:"column:image"`
	Info        string    `gorm:"column:info"`
	Label       string    `gorm:"column:label"`
	Content     string    `gorm:"column:content"`
	Category_id int       `gorm:"column:category_id"`
	Create_at   time.Time `gorm:"column:create_at"`
}

type SelectArticle struct {
	Id    int    `gorm:"column:id"`
	Title string `gorm:"column:title"`
}

type SelectLabel struct {
	Id         int    `gorm:"column:id"`
	Label_name string `gorm:"column:label_name"`
}

type SiteInfo struct {
	Personal_introduction string `gorm:"column:personal_introduction"`
	Contact               string `gorm:"column:contact"`
	About                 string `gorm:"column:about"`
}

//返回首页数据
//article:文章主体数据、 selectArticle:文章精选、 recoArticle:文章推荐、selectLabel文章标签、indexAbout:关于、indexContact：联系
func IndexArticle() (result Find) {
	var (
		article       []Article
		selectArticle []SelectArticle
		recoArticle   []SelectArticle
		selectLabel   []SelectLabel
		indexAbout    SiteInfo
		indexContact  SiteInfo
	)
	article = make([]Article, 100)
	selectArticle = make([]SelectArticle, 100)
	recoArticle = make([]SelectArticle, 100)
	selectLabel = make([]SelectLabel, 100)

	G_db.Debug().Table("article").Select("id,title,auth,image,info").Where("article_status = '1'").Limit(3).Order("create_at desc").Scan(&article)
	G_db.Debug().Table("article").Select("id,title").Where("selected_articles_status = '1' and article_status = '1'").Limit(6).Order("create_at desc").Scan(&selectArticle)

	G_db.Debug().Table("article").Select("id,title").Where("selected_articles_status = '1' and article_status = '1'").Limit(6).Order("create_at desc").Scan(&recoArticle)
	G_db.Debug().Table("article_label").Select("id,label_name").Order("id desc").Scan(&selectLabel)

	G_db.Debug().Table("users").Select("about").Scan(&indexAbout)
	G_db.Debug().Table("users").Select("contact").Scan(&indexContact)
	result = Find{
		Article:       article,
		SelectArticle: selectArticle,
		RecoArticle:   recoArticle,
		SelectLabel:   selectLabel,
		IndexAbout:    indexAbout,
		IndexContact:  indexContact,
	}
	for _, v := range result.Article {
		fmt.Printf("%v,%v\n", v.Id, v.Title)
	}

	for _, v := range result.SelectArticle {
		fmt.Printf("%v,%v\n", v.Id, v.Title)
	}

	return
}

三：展示前端页面 你们就能理解：
