laravel 有一个无法得到结果

laravel hasone not able to get the result

我正在尝试获取用户的角色,无论是管理员还是具有 hasOne 关系的客户端,但是当我尝试获取详细信息并执行 dd 时,我将 exists 设置为 false 任何人都可以帮助我吗

this is the result when im using dd in controller

//migration for user
public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('email')->unique();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
}

//角色迁移

public function up()
{
    Schema::create('roles', function (Blueprint $table) {
        $table->increments('id');
        $table->unsignedInteger('user_id');
        $table->enum('role',['Club Manager','Admin','Mc']);
        $table->foreign('user_id')->references('id')->on('users');            
        $table->timestamps();
    });
}

//用户模型

<?php

 namespace App;

 use Illuminate\Notifications\Notifiable;
 use Illuminate\Foundation\Auth\User as Authenticatable;
 use \App\Role;

 class User extends Authenticatable
 {
 use Notifiable;


/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = [
    'name', 'email', 'password',
];

/**
 * The attributes that should be hidden for arrays.
 *
 * @var array
 */
protected $hidden = [
    'password', 'remember_token',
];

public function Role(){
    return null;
}
public function getrole(){
    $role=$this->hasMany('App\Role');

    return $role;
}
public function getuserRole(){
    return Role::where('user_id',$this->id)->first();
}
} 
//Controller
public function getrole(){
dd(Auth::user()->getrole());
 }

您必须以 属性 而非方法的形式访问关系:

Auth::user()->getrole;
