Laravel 5 with entrust - hasRole not working
提问by Dylan Glockler
I have a logged in user and the code here works:
我有一个登录用户，这里的代码有效：
@if( Auth::check() )
Logged in as: {{ Auth::user()->firstname }} {{ Auth::user()->lastname }}
@endif
I'm using zizaco/entrust and it's all working. I've created roles and permissions and given my user the admin role which has administrative permission.
我正在使用 zizaco/entrust 并且一切正常。我已经创建了角色和权限，并为我的用户授予了具有管理权限的 admin 角色。
So why doesn't this work:
那么为什么这不起作用：
$user = Auth::user();
print_r($user->hasRole('admin'));
If I print_r the $user I can see that the Auth user is loaded, but hasRole is not working. I was just testing this within the blade template at the moment but tried it in the Controller with the same result. My error is:
如果我 print_r $user 我可以看到 Auth 用户已加载，但 hasRole 不起作用。我当时只是在刀片模板中测试它，但在控制器中尝试它并得到相同的结果。我的错误是：
BadMethodCallException in Builder.php line 1992:
Call to undefined method Illuminate\Database\Query\Builder::hasRole()
My user model:
我的用户模型：
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Zizaco\Entrust\Traits\EntrustUserTrait;
class User extends Model {
use EntrustUserTrait;
protected $table = 'users';
public $timestamps = true;
use SoftDeletes;
protected $dates = ['deleted_at'];
}
UPDATE
更新
I realized hasRole works for me when I look up the user this way (returns App\Models\User Object):
当我以这种方式查找用户时，我意识到 hasRole 对我有用（返回 App\Models\User Object）：
$user = \App\Models\User::find( \Auth::user()->id );
but NOT when I find the user this way (returns App\User Object ):
但不是当我以这种方式找到用户时（返回 App\User Object ）：
$user = \Auth::user();
I rather would have thought it would work the other way, when I pull up the App\User I'd have access to hasRole but not necessarily when I search for a user. I thought hasRole would work right from the Auth::user() without having to lookup the user with the user model...???
我宁愿认为它会以另一种方式工作，当我拉起 App\User 时，我可以访问 hasRole 但不一定在我搜索用户时。我认为 hasRole 可以直接从 Auth::user() 工作，而不必使用用户模型查找用户......？？？

Thanks for you update, it was a problem for me as well. And I used your advice and I put in my HomeController
感谢您的更新，这对我来说也是一个问题。我使用了你的建议并放入了我的 HomeController
public function index()
{
$user = User::find( \Auth::user()->id );
return view('home', compact('user'));
}
and then in my Home View
然后在我的主页视图中
@if ($user->hasRole('Admin'))
<li><a href="/users/create">Create User</a></li>
@endif
<li><a href="/users">User List</a></li>
<li><a href="">Create Client</a></li>
<li><a href="">Create Payment</a></li>
and everything works perfect...
一切都很完美......
