Laravel Livewire 分页

Question

Laravel - 8.6.0 (Jetstream), Livewire - 2.2.7

除其他内容外，我有两个简单的 tables，其中包含使用 Livewire 呈现的搜索输入。两个 Livewire 组件具有几乎相同的逻辑，主要区别在于数据库查询格式。在第一个 table（搜索、分页）中，一切都运行良好，但在第二个 table 中，分页出现问题。

怎么了？ 当我点击分页 link（例如从 first-page 转到第（2）页）时，请求被发送，浏览器中的 URL 变为正确的查询字符串，一个收到响应，但响应中没有 HTML 部分，DOM 没有变化，分页显示第一页处于活动状态。如果我手动刷新页面，table 显示第 2 页的数据，之后，我什至可以获得下一页或上一页的新数据，但只能在初始页面刷新后获得一次。如果我再次单击分页 links，没有 HTML 数据响应，没有 DOM 变化 ...

我尝试了什么？

我已经阅读了 Livewire 文档，尝试了“疑难解答”部分建议的所有解决方案。
我检查了我的代码多次，比较了 Livewire 组件和 Blade 视图，没能找到一些明显的错误。
在过去的 10 天里，我一直在 SO、Livewire 论坛、Laracast 论坛上寻找答案...找到了一些很好的建议，尝试了大部分，但是 none 解决了我的问题。
消除了数据库查询逻辑导致某些问题的可能性，即使我不使用复杂的记录过滤（例如，如果我只是对所有记录进行分页 - Model::all()->paginate( 10)).
有问题 table 通过单选按钮进行了一些额外的记录过滤，我暂时删除了它，但问题仍然存在。

工作 Livewire 组件和 Blade 视图的代码：

<?php

namespace App\Models;

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

class Extension extends Model
{
    use HasFactory;
    protected $guarded = [];

    public function user()
    {
        return $this->belongsTo('App\Models\User', 'directory', 'ext');
    }

    public static function search($query)
    {
        return empty($query) ? static::query()
            : static::where('directory', 'like', '%' . $query . '%')
            ->orWhere('mobile', 'like', '%' . $query . '%')
            ->orWhere('department', 'ilike', '%' . $query . '%')
            ->orWhere('name1', 'ilike', '%' . $query . '%')
            ->orWhere('name2', 'ilike', '%' . $query . '%');
    }
}

在等待任何建议的同时，我将再尝试一次干净的 Laravel/Jetstream/Livewire 安装。提前致谢，非常感谢任何帮助！

Answer 1

通过再次查看我的代码，我注意到模型 classes 中有一些“剩余”。在模型 class 中不应该有 "use WithPagination;" Livewire 特征！当我删除“使用”状态网并清除视图缓存时，一切正常！
