Laravel 错误：尝试获取非对象的属性

我有table

Authors

和table

Uploads

，我只是试图通过

Uploads

表中的

author\u id

获取某个作者的所有上传

为此，我的控制器中有一个如下所示的方法：

public function author_works()
    {

        $uploads= Upload::where('author_id', 3)->first();

        return view('author-works')->with('uploads',$uploads);
    }

我的看法是：

  @extends('layouts.app')
@section('content')
    <h1>Uploads</h1>
    @if(count($uploads)>0)
        @foreach($uploads as $upload)
            <div class="well">
                <h3><a href="/uploads/{{$upload->id}}">{{$upload->name}}</a> </h3>
                <small>Written on {{$upload->created_at}}</small>

            </div>
        @endforeach
      {{--  {{$uploads->links()}}--}}
    @else
        <p>No uploads found</p>
    @endif

@endsection

有人能解释我为什么会出错吗？

当您使用

first（）

方法时。使用

get（）

：

---

first

将只提供一条记录，因此您不能在一条记录中使用循环，而是使用

get（）

函数谢谢您的回答和指向另一条记录的链接。这有助于：）

 #attributes: array:9 [▼
    "id" => 7
    "name" => "Fsdf"
    "description" => "fsdfsdffds"
    "created_at" => "2017-12-07 21:29:53"
    "updated_at" => "2017-12-07 21:29:53"
    "user_id" => 1
    "avtor_id" => 3
  ]
  #original: array:9 [▼
    "id" => 7
    "name" => "Fsdf"
    "description" => "fsdfsdffds"
    "created_at" => "2017-12-07 21:29:53"
    "updated_at" => "2017-12-07 21:29:53"
    "user_id" => 1
    "avtor_id" => 3
  ]

$uploads = Upload::where('author_id', 3)->get();
