无法为用户分配角色

Question

我试图在我的 Laravel 应用程序上使用 spatie(laravel-permission)，但我无法为用户分配角色。我面临的错误是

调用未定义的方法 Illuminate\Database\Query\Builder::assignRole()

管理员控制器.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
use Spatie\Permission\Models\Role;
use Spatie\Permission\Models\Permission;
use Spatie\Permission\Traits\HasRoles;
class AdminsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $users = User::all();

        return view('admin.dashboard', compact('users'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        $user = User::whereId($id)->firstOrFail();
        // $user->hasAllRoles(Role::all());
        return view('admin.show', compact('user'));
    }

    public function assignRole($id){
        $user = User::whereId($id)->firstOrFail()->assignRole('Staff');
        redirect('/dashboard');

    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
         $user = User::whereId($id)->firstOrFail();
         $user->destroy();

         redirect('/dashboard');
    }
}

Answer 1

use HasRoles;在您的用户模型中添加特征。

将其导入use Spatie\Permission\Traits\HasRoles;模型文件的顶部。

Answer 2

将 Spatie\\Permission\\Traits\\HasRoles 特征添加到您的 User 模型中：

\n

<?php\n    namespace App\\Models;\n    use Illuminate\\Foundation\\Auth\\User as Authenticatable;\n    use Spatie\\Permission\\Traits\\HasRoles;\n\n    class User extends Authenticatable\n    {\n        use HasRoles;\n        // \xe2\x80\xa6\n    }\n

\n

这是Spatie 权限的完整示例
