Laravel 5.2 Eloquent 关系 return 多维数组

Question

这是可能的路线代码

Route::get('/dashboard',['middleware' => 'auth', function () {

    $links = App\Website_links::where('website_id',1)->get();
    return view('user.dashboard',['links_data'=>$links]);

}]);

和website_link型号代码是

class Website_links extends Model
{
   public $timestamps = false;
   protected $table = 'website_links';

    public function project()
    {
        return $this->belongsTo('App\Website','website_id')
                    ->select('project_name','project_status');
    }
 }

并查看代码

@foreach($links_data as $links)
         <tr>
         <td><a href="">{{$links['page_url']}}</a></td>
         <td>{{$links['project']}}</td>// here i want to display project_name from website table
         </tr>
    @endforeach

数据库模式：

  website : id,project_name,project_status
  website_links: id, page_url, website_id   //here website_id is forign key.

现在可以正确显示 page_url 但

{{$links['project']}} display {"project_name":"Project1","id":45}

我想显示 project_name 值，如 project1 而不是整个数组

  {"project_name":"Project1","id":45}

Answer 1

改变

$links['project'] to $link->project->project_name

@foreach($links_data as $links) 
     <tr>
         <td>
             <a href="">{{$links['page_url']}}</a>
         </td> 
        <td>
             {{$links->project->project_name}}
        </td>// here i want to display project_name from website table
     </tr> 
@endforeach

并将您的查询更改为以下内容以防止 N+1 查询问题

$links = App\Website_links::with('project')->where('website_id',1)->get();
