Livewire 挂载突然停止接收参数

Question

我有一个通过路由模型绑定显示模型的 livewire 组件，它工作正常但突然收到以下错误：

Too few arguments to function Livewire\LivewireManager::mount(), 0 passed in

以下是我的代码示例：

路线 web.php

Route::middleware(['auth:sanctum', 'verified'])->group(function() {
    Route::get('/admin/intro-section', \App\Http\Livewire\Admin\AdminIntroSection::class)->name('admin.intro-section.index');
    Route::get('/admin/intro-section/{id}', \App\Http\Livewire\Admin\AdminIntroSectionShow::class)->name('admin.intro-section.show');
});

Livewire\Admin\

中的 Livewire 组件 class

<?php

namespace App\Http\Livewire\Admin;

use Livewire\Component;
use App\Models\IntroSection;
use Illuminate\Support\Collection;
use Livewire\WithFileUploads;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

class AdminIntroSectionShow extends Component
{
    use WithFileUploads;

    public IntroSection $introSection;
    public $photo;

    protected $rules = [
        'introSection.title' => 'string',
        'introSection.description' => 'string',
        'introSection.link' => 'string',
        'introSection.img_link' => 'string',
        'photo' => 'nullable|image|max:2000',
    ];

    public function update(IntroSection $introSection, Request $request)
    {
        $this->validate();
        if ($this->photo) {
            $filename = $this->photo->store('img', 'public');
            $this->introSection->img_link = $filename;
        }
        $this->introSection->save();
    }

    public function mount($id)
    {
        $this->introSection = IntroSection::where('id', $id)->with(['details'])->first();
    }

    public function render()
    {
        return view('livewire.admin.intro-section-show');
    }
}

重现步骤

在 web.php
添加路线
php artisan make:livewire Admin\AdminIntroSectionShow
名为“IntroSection”的模型具有以下属性：

'title' => (字符串), 'description' => (文本), 'link' => (字符串), img_link' => (字符串)

您使用的是最新版本的 Livewire：是

代码最后一次运行是在我完成文件上传部分之前。之后，我测试了有效的文件上传。满意后重新加载了页面，但是现在mount好像不喜欢了

关于如何解决这个问题有什么想法吗？我尝试删除更新功能，将 IntroSection $introsection 传递给 mount 而不是 $id。就我而言，livewire 组件似乎没有什么是微不足道的，但无论如何：

        <h2 class="font-semibold text-xl text-gray-800 leading-tight">
            {{ __('Intro Section') }}
        </h2>
    </x-slot>

还原了添加进度条之前的所有更改。罪魁祸首似乎是我从 Livewire Added File Upload Support:

复制的以下代码块

<div
    x-data="{ progress: 0, uploading: false }"
    @livewire-upload-start="uploading = true"
    @livewire-upload-finish="uploading = false"
    @livewire-upload-error="uploading = false"
    @livewire-upload-progress="progress = $event.detail.progress">
    <input type="file" name="img_link" wire:model="photo" class="block mt-2">
    <progress max="100" x-bind:value="progress" x-show="uploading"></progress>
</div>

我在使用 Alpinejs 但同时使用了 @livewire 指令导致了错误。

我从 https://laravel-livewire.com/docs/2.x/file-uploads#js-hooks:

获得的更新代码

<div
    x-data="{ isUploading: false, progress: 0 }"
    x-on:livewire-upload-start="isUploading = true"
    x-on:livewire-upload-finish="isUploading = false"
    x-on:livewire-upload-error="isUploading = false"
    x-on:livewire-upload-progress="progress = $event.detail.progress"
                        >
    <input type="file" name="img_link" wire:model="photo" class="block mt-2">
    <div x-show="isUploading">
        <progress max="100" x-bind:value="progress"></progress>
    </div>
</div>
