一、创建设置

修改 app/User.php

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

public function setting()
{
    return new Setting($this);
}

新建文件：app/Setting.php

namespace App;

class Setting
{
    protected $allowed = ['city','bio'];

    protected $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    public function merge(array $attribute)
    {
        $setting = array_merge($this->user->setting, array_only($attribute,$this->allowed));
        return $this->user->update(['setting'=>$setting]);
    }
}

二、创建控制器

创建设置控制器

php artisan make:controller SettingController

修改 app/Http/Controllers/SettingController.php

namespace App\Http\Controllers;

class SettingController extends Controller
{
    public function index()
    {
        return view('users.setting');
    }

    public function store()
    {
        user()->setting()->merge(request()->all());
        return back();
    }
}

注册路由

Route::get('setting', 'SettingController@index');
Route::post('setting', 'SettingController@store');

三、创建视图

创建文件：resources/views/users/setting.blade.php

访问：http://127.0.0.1:8000/setting 进行测试
