Route.PHP

Route::get('setting',function(){
    return \App\User::first()->skills();
});

user.PHP的

protected $casts = [
    'skills' => 'json'
];

public function skills(){
    return new Skills($this,$this->skills);
}

Skills.PHP

namespace App;
use App\User;
use Mockery\Exception;

class Skills
{
    protected $user;
    protected $skills = [];

    public function __construct(User $user,array $skills){

        $this->user=$user;
        $this->skills=$skills;
    }
}

我想进入/设置页面我有“响应内容必须是实现__toString()的字符串或对象,”对象“给出.”错误.

我尝试在路由中添加dd()函数的返回,我看到所有JSON数据但是$skills-> get(),$skill-> set()当时没有工作.
