第一次求教，关联查询问题。

啊 重新便编辑把. 关于 关联查询的问题,几个小时还没解决,硬是不知道哪里有问题..
News表里有一个avatars_id的字段关联到了avatar表里的id

News.php

class news extends Model {

    public function avatar()
    {
        return $this -> belongsTo('App\Avatar');
    }
}```

Avatar.php

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Avatar extends Model {

public function news()
{
    return $this -> hasMany('App\News');
}```

NewsController.php

    public function index()
    {
        $articles = News::with('avatar')->latest()->paginate(8);
        return view('NewHome', compact('articles'));
    }

NewHome.blade.php

            @foreach ($articles as $page)
            <div class="col-md-3">
                <div class="panel panel-default">
                    <div class="panel-heading" style="white-space:nowrap;overflow:hidden;text-overflow:clip;">
                        <a title="{{ $page->title }}" href="{{ URL('news/'.$page->id) }}"> <h4>{{ $page->title }}</h4></a>
                    </div>
                    <div class="panel-body">
                        <a title="{{ $page->title }}" href="{{ URL('news/'.$page->id) }}"><img src="{{$page->avatars_id->url}}" alt="" width="180px"></a>
                    </div>
                </div>
            </div>
            @endforeach
