我想要判断某个评论的user_id是不是这篇文章的user_id，“文章”及“评论”的模型和控制文件应该如何修改？

想要的效果：

我想要在一个“评论”的视图文件中，判断某个评论的user_id是不是这篇文章的user_id，但我自己无论怎么尝试，都无法获取$article->user_id的数据，诚心请教各位：“文章”及“评论”的模型和控制文件应该如何修改？

1. “评论”的视图文件：item.blade.php

<div class="media-heading">
    <a href="{{ route('auth.space.index',['user_id'=>$comment->user->id]) }}" target="_blank">{{ $comment->user->name }} @if($comment->user->authentication && $comment->user->authentication->status === 1)<span class="text-yellow"><i class="iconfont icon-vip-o" aria-hidden="true" data-toggle="tooltip" data-placement="right" title="" data-original-title="已通过达人认证"></i></span>@endif</a>

    @foreach($articles as $article)
        @if($source_type === 'article' && $comment->user_id === $article->user_id)
            <span class="label-xs label-success">作者</span>
        @endif
    @endforeach

    @if($comment->to_user_id)
        <span class="text-muted"> • 回复 • </span>
        <a href="{{ route('auth.space.index',['user_id'=>$comment->to_user_id]) }}" target="_blank">{{ $comment->toUser->name }} @if($comment->toUser->authentication && $comment->toUser->authentication->status === 1)<span class="text-yellow"><i class="iconfont icon-vip-o" aria-hidden="true" data-toggle="tooltip" data-placement="right" title="" data-original-title="已通过达人认证"></i></span>@endif</a>
    @endif
</div>

2. 模型文件：

1). “评论”的模型文件：Comment.php

<?php

    public static function boot()
    {
        parent::boot();

        /*监听创建*/
        static::creating(function($comment){
            /*开启状态检查*/
            if(Setting()->get('verify_comment')==1){
                $comment->status = 0;
            }
        });

        /*监听删除事件*/
        static::deleting(function($comment){
            /*问题、回答、文章评论数 -1*/
            $comment->source()->where("comments",">",0)->decrement('comments');
        });
    }

    public function source()
    {
