Question

我正在使用laravel制作社交网络，我想要展示＆＃34; ＆＃39;后＆＃39; ＆＃39;意见＆＃39; ＆＃39; comment_by＆＃39;具有嵌套关系的单个数组中的用户信息

这是我的类和数据库结构

表名和字段

成员

         ID => primary key,
         name,
         email

帖子

         ID => primary key,
         postText
         fromUserId => foreign key (Members-id)

评论

         commentText ,
         onPostId = > foreign key (Post-id)
         fromUserId = > foreign key (Members-id)

雄辩的模特

Member.php

类成员扩展了Model { // }
post.php中

类post扩展Model {     //     public $ timestamps = true;

function getUserDetails（） {     返回$ this-＆gt; belongsTo（＆＃39; App \ Member＆＃39;，＆＃39; fromUserId＆＃39;，＆＃39; id＆＃39;）; }

function getCommentDetails（） {     返回$ this-＆gt; hasMany（＆＃39; App \ comment＆＃39;，＆＃39; onPostId＆＃39;，＆＃39; id＆＃39;）; }

}

3.Comment.php

class comment extends Model
  {


  }

要求获取数组

 $posts=post::with('getUserDetails','getCommentDetails')->get();

Answer 1

根据您的评论，只需将commentedBy关系添加到您的Member模型并急切加载即可。

在评论模型中。

public function commentedBy()
{
    return $this->belongsTo('App\Member', 'fromUserId', 'id');
}

然后急切加载关系。

$posts = post::with('getUserDetails','getCommentDetails.commentedBy')->get();
