我在显示使用 spatie 媒体库和灯丝管理面板上传的图像时遇到问题。

用于澄清的图像

这是表单架构的代码：

SpatieMediaLibraryFileUpload::make('thumbnail')->collection('posts')

这是表列的代码

SpatieMediaLibraryImageColumn::make('thumbnail')->collection('posts')

谢谢。

我有一个 Laravel 9 项目，我在其中使用 UUID。我刚刚安装了 Spatie Permissions 包，并按照说明将其与 UUID 一起使用...但是当我尝试这样做时，assignRole出现以下错误；

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`project`.`model_has_roles`, CONSTRAINT `model_has_roles_role_id_foreign` FOREIGN KEY (`role_id`) REFERENCES `roles` (`id`) ON DELETE CASCADE) (SQL: insert into `model_has_roles` (`model_id`, `model_type`, `role_id`) values (1d6535d1-01f0-43b4-8701-4e3c76ad1587, App\Models\User, 0))

我认为这可能与软件包附带的 Spatie 迁移有关。我已经按照https://spatie.be/docs/laravel-permission/v5/advanced-usage/uuid#content-migrations..更新了它，如下所示；

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`project`.`model_has_roles`, CONSTRAINT `model_has_roles_role_id_foreign` FOREIGN KEY (`role_id`) …

当我尝试登录或注册或尝试访问受限制的页面时，会显示此错误。如何解决这个错误？

Declaration of App\Http\Middleware\Authenticate::handle($request, Closure $next) must be compatible with Illuminate\Auth\Middleware\Authenticate::handle($request, Closure $next, ...$guards)

这是 /app/Http/Middleware/Authenticate.php 代码：

<?php

namespace App\Http\Middleware;

use Illuminate\Auth\Middleware\Authenticate as Middleware;
use Closure;
use Auth;
class Authenticate extends  Middleware
{
    public function handle($request, Closure $next)
    {
        if (Auth::check()) {
            return $next($request);
        }
        return redirect()->route('user.login');
    }

}

我在这个变量中有一个日期

$start_date = '2021-03-04';

我想检查这个日期是否比当前日期早三个月我如何检查

if($start_date < 3 months ???)
{

}

我尝试运行npm run dev并收到此错误：

我试过了：

• composer update
• rm -rf node_modules
• npm cache clean
• npm install
• npm outdated
• npm install
• npm run dev

但还是没用。有人能帮我吗？

我想添加一些数据，但出现 BadMethodCallException Call to undefined method App\Models\BatterFirst::index() 错误，其中我的模型 BatterFirst.php 是

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class BatterFirst extends Model
{
    use HasFactory;

    protected $fillable = [
        'name', 'runs', 'balls', 'sixs', 'fours'
    ];
}

这是我的控制器 BatterFirstController.php

<?php

namespace App\Http\Controllers;

use App\Models\BatterFirst;
use Illuminate\Http\Request;

class BatterFirstController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $data = BatterFirst::latest()->paginate(5);

        return view('BatterFirst.index',compact('data'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }

在 Macos上将 PHP 升级到 8.0 后，我尝试升级 Laravel brew，但出现以下错误。我应该如何修复它？
