如何在职业解决方案表中从用户那里获取角色？

Question

我想角色（role_users从每用户表）career_solutionstable.I'm尝试添加一些图标供用户使用，但我只是做图标过滤一个大的疑难问题events，opinion以及news，但Career solution没有工作。

对于events，opinion和news我用：

$temp['role'] = $events->user->role;

$temp['role'] = $opinion->user->role;

$temp['role'] = $news->user->role;

现在我正在尝试获得相同的值，$career_solution但$career_solution->user->role似乎不再起作用了......

这是我的职业解决方案.php：

 <?php

namespace App;

use Illuminate\Database\Eloquent\Model;

use Illuminate\Pagination\LengthAwarePaginator;

use Illuminate\Support\Collection;

class CareerSolution extends Model

{

    protected $table = 'career_solutions';

    public $timestamps = false;

    protected $fillable = [

        'user_id', 'subject','topic_category_id','topic_subcategory_id','quantity','expires_at','public','location','date','added','views','on_offer','optional','city','employment_type','estimated_salary','url','type','job_id','company','modified_date','city','indeedApply'

    ];

    public function user()

    {

        return $this->belongsTo('App\User','user_id','id');

    }

    public function country()

    {

        return $this->belongsTo('App\Country','location','id');

    }

    public function category()

    {

        return $this->belongsTo('App\Category','topic_category_id','id');

    }

    public function sub_category()

    {

        return $this->belongsTo('App\CareerSolutionCategory','topic_subcategory_id','id');

    }

}
