檢查用戶是否是laravel中的管理員

Question

我想檢查用戶是否爲admin。

User table

id | role_id | name 
1 | 3  | test 

Role table

id | role  
1 | user  
2 | employee 
3 | admin  

User model

class User extends Authenticatable 
{ 
use Notifiable; 

protected $fillable = [ 
    'name', 'email', 'gender', 'password', 
]; 

protected $hidden = [ 
    'password', 'remember_token', 
]; 

public function roles() 
{ 
    return $this->belongsToMany('App\Role'); 
} 

public function isAdmin() { 
    return $this->roles()->where('role', 'user')->exists(); 
} 

}

Role model

class Role extends Model 
{ 
// 
} 

Blade template

@if(Auth::user()->isAdmin()) 
    user is admin 
@endif 

我無法找到答案我有什麼在function isAdmin沒有增加任何新的作品。現在我得到錯誤基表或視圖找不到。

試試這個

class User extends Authenticatable 
{ 
use Notifiable; 

protected $fillable = [ 
    'name', 'email', 'gender', 'password', 
]; 

protected $hidden = [ 
    'password', 'remember_token', 
]; 

public function role() 
{ 
    return $this->belongsTo('App\Role'); 
} 

public function isAdmin() { 
    if($this->role->name == 'admin'){ 
     return true; 
    } 
    return false; 
}
