Question

我有三个关系模型：

课程评论

class Comment extends Eloquente {

  use UserTrait, RemindableTrait;

  protected $table = 'comments';


  public function user()
  {
    return $this->belongsTo ('User');
  }

  public function post()
  {
    return $this->belongsTo('Post');
  }
}

类用户

class User extends Eloquent  {
  use UserTrait, RemindableTrait;

  /**
  * The database table used by the model.
  *
  * @var string
  */
  protected $table = 'users';

  /**
  * The attributes excluded from the model's JSON form.
  *
  * @var array
  */
  protected $hidden = array('password', 'remember_token');

  public function post()
  {
    return $this->hasMany('Post');
  }

  public function comment()
  {
    return $this->hasMany('Comment');
  }
}

课程

class Post extends Eloquent {
  use UserTrait, RemindableTrait;

  /**
   * The database table used by the model.
   *
   * @var string
   */
  protected $table = 'posts';

  /**
   * The attributes excluded from the model's JSON form.
   *
   * @var array
  */
  protected $hidden = array('password', 'remember_token');


  public function comment()
  {
    return $this->hasMany('Comment');
  }
  public function user()
  {
    return $this->belongsTo('User');
  }
}

在控制器中简单

return View::make('viewfile',['feed'=> Post::all()]);

查看文件：

@foreach($feed as $post)

     @foreach($post->comment as $comment)
        {{$comment->user->username}}
     @endforeach
@endforeach

在视图文件中，它返回未定义的属性 if var_dump() ;仅返回true 但是如果我把这个foreach循环放在控制器函数中返回值$comment->user->username，返回用户名所以我的问题是我该怎么做才能使用这个属性在视图文件

控制器

<?php

class BoardController extends \BaseController {

    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        if(Auth::check())
        {
            $followers_count = sizeof(unserialize(Auth::user()->Followers));
            $following_count = sizeof(unserialize(Auth::user()->Following));
            $following_groups_count = sizeof(unserialize(Auth::user()->GroupsFollowing));
            $feed = Post::all();

            foreach ($feed as $post) {

                foreach($post->comment as $comment)
                {
                    return $comment->user->username;
                }
            }


             /*

            return View::make('board.index',[
                    'FollowersCount' => $followers_count,
                    'FollowingCount' => $following_count,
                    'FollowingGroupsCount' => $following_groups_count,
                    'feed' => $feed,
                    'nick' => Auth::user()->username
                ]);
            */
        }
        else
        {
            Redirect::to('/login');
        }
    }




}

Answer 1

尝试使用函数collect（$ yourArray）创建dataCollection，然后使用＆＃34;发送到带有＆＃34;的视图。功能

我没有使用hasOne或其他任何东西，我使用model :: find（$ id）来搜索相同的id

例如： $ dataCollection = collect（$ array1）;

该函数用于匹配laravel的默认格式

顺便说一句，我正在使用laravel 5.4

laravel Eloquent Relations无法访问Property
