循环通过关系Laravel

Question

堆栈溢出,

我想要完成的事情:

我想循环通过数据库找到所有(英雄)与他们的相关(访谈).我还希望每次采访都与它相关(故事)和(图像).到目前为止,我可以dd($英雄),我可以看到阵列正确地抓住每个英雄的面试,每次采访都有相关的图像和故事.如何正确循环？

错误

Invalid argument supplied for foreach() (View: /Users/plastics1509moore/Desktop/elephant_gin/resources/views/administration/index.blade.php)

这就是我所做的:

控制器:

$heroes = Hero::with('Interview', 'Interview.stories', 'Interview.images')->orderBy('position', 'asc')->get();

模型关系:

英雄:

public function Interview()
{
    return $this->hasOne('App\Interview', 'heroInt_id');
}

专访:

    public function relationships()
{
    return $this->belongsTo('App\Hero');
}
public function stories()
{
    return $this->hasMany('App\InterviewStory');
}
public function images()
{
    return $this->hasMany('App\InterviewImage');
}

InterviewImage:

 public function relationships()
{
    return $this->belongsTo('App\Interview');
}

InterviewStory

public function relationships()
{
    return $this->belongsTo('App\Interview');
}

HTML:

环:

    @foreach($heroes as $hero)
       @foreach($hero->Interview as $story)
         <div>{{$story->id}}</div>
        @endforeach    
    @endforeach

Answer 1

你不能循环采访,因为这是一种hasOne关系.你可能想做的是

@foreach($heroes as $hero)
   @foreach($hero->interview->stories as $story)
     <div>{{$story->id}}</div>
    @endforeach    
@endforeach
