Question

我正在尝试获取所有包含报告的帖子，然后急于加载报告。

关系

//Post.php

public function reports()
{
    return $this->morphMany('App\Report', 'reportable');
}

//Report.php

public function reportable()
{
    return $this->morphTo();
}

报表控制器

public function postReportsIndex()
{
    $posts = Post::whereHas('reports')
                    ->with('reports.creator', 'comments')
                    ->latest()
                    ->paginate();

    //return view('channels.reports.post-reports', compact('posts'));

    return $posts;
 }

JSON输出

当我return $post;并获取JSON输出时，一切正常，帖子reports: []就在那里。

刀片模板

<h1>Reports For Posts</h1>
<hr>
@foreach($posts as $post)
    <ul>
        <li>
            <h4><a href=" forums/{{$post->slug}} ">{{ $post->title }}</a></h4>
            <span class="social-share-title pull-left text-capitalize">
                By <a href="#">{{ $post->creator->username }}</a> 
                {{$post->created_at->format('F d, Y') }}
            </span>
            </br></br>
            <ul>
                {{$post->reports}}
            </ul>
        </li>
    </ul>
    <hr>
@endforeach

问题

由于某种原因，当我尝试使用刀片获取帖子报告时，我在屏幕上看到的都是“ 0”

当我尝试遍历报告时，出现错误：

<ul>
    @foreach($post->reports as $report)
        <li>
            {{ $report->content }} <i> By {{ $report->user }}</i>
            <p>{{$report->created_at}}</p>
        </li>
    @endforeach
</ul>

为foreach（）提供的参数无效（查看：/Applications/MAMP/htdocs/community/resources/views/channels/reports/post-reports.blade.php）

刀片模板中的多态关系返回0，但在json输出中正常显示
