laravel - Laravel 5.6 - 类名必须是有效的对象或字符串

问题描述

我的 Laravel 应用程序抛出下一个错误：

(1/1) Error

Class name must be a valid object or a string
in HasRelationships.php line 656

我不得不说，现在这个项目是在一个共享主机中，但这是唯一根本不起作用的部分。这是 HTML 文件：

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-10">
            <div class="card">
                <div class="card-header text-uppercase text-center"><b>Dashboard administrativo</b></div>
                <div class="card-body">

                  <div class="card mb-3">
                    <div class="card-header">

                        <thead>
                          <tr>
                            <th class="text-center">#</th>
                            <th>Nombre</th>
                            <th>Correo</th>

                          </tr>
                        </thead>
                        <tbody>
                          @foreach ($users as $user)
                            <tr>
                              <td class="text-center">{{ $user->id }}</td>
                              <td>{{ $user->name }}</td>
                              <td>{{ $user->email }}</td>
                              <td>
                                <div class="btn-group fullwidth" role="group">
                                  <a href="{{ route('user.show', $user->id) }}" class="btn btn-primary" role="button">Ver</a>
                                  <a href="{{ route('user.edit', $user->id) }}" class="btn btn-success" role="button">Editar</a>
                                </div>
                              </td>
                            </tr>
                          @endforeach
                        </tbody>
                      </table>
                      {{ $users->links() }}
                    </div>
                  </div>

                </div>
            </div>
        </div>
    </div>
</div>
@endsection

这是我的控制器：

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Auth;

use App\Role;
use App\Permission;
use App\User;
use App\Share;

class AdminController extends Controller
{
    public function dashboard()
    {

      $users = new User();
      $queries = [];

      $columns = [
          'gender',
      ];

      foreach ($columns as $column) {

          if(request()->has($column)) {
              $users = $users->where($column, request($column));
              $queries[$column] = request($column);
          } // if

      } // foreach

      if(request()->has('sort')) {
          $users = $users->orderBy('name', request('sort'));
          $queries['sort'] = request('sort');
      } // if

      $users = $users->paginate(10)->appends($queries);

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

    } // dashboard
}

为什么我的代码在我的机器上开发时可以完美运行，但在托管时却不能？我在网上寻找解决方案，但我得到的一切都与Entrust我根本没有使用的有关。任何想法？

编辑：App\User

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Spatie\Permission\Traits\HasRoles;

class User extends Authenticatable
{
    use Notifiable, HasRoles;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password', 'gender', 'identification', 'phone', 'country', 'city', 'provider', 'provider_id', 'birthday', 'referred_by', 'affiliate_id',
    ];

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

    public function shares()
    {
      return $this->hasMany('App\Share');
    }

    public function storeProvider()
    {
      return $this->hasOne('App\Provider');
    }

    public function messages()
    {
      return $this->hasMany('App\Message');
    }
}

这是整个错误：

解决方案

正如@erubiel 和@farid-silva 所指出的，您可能需要解决生产环境中的PHP 版本。

但是，最接近的问题是Spatie\Permission\Traits\HasRoles::roles调用Illuminate\Database\Eloquent\Concerns\HasRelationships::morphToMany：

  • related
  • table， 和
  • foreignKeyPivot

全部设置为null。

如果你看一下代码，这些值来自 Laravel 配置，即：

  • permission.models.role
  • permission.table_names.model_has_roles， 和
  • permission.column_names.model_morph_key

所以可能值得检查您的配置，即permission值集，以检查这些是否在生产中正确定义。
