Laravel Livewire 模型属性绑定

Question

这是我的 Livewire 组件

<?php

namespace App\Http\Livewire\Dashboard;

use App\Models\Post;
use Livewire\Component;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

class EditPost extends Component
{
    use AuthorizesRequests;

    public ?Post $postSingle = null;

    protected $rules = [
        'postSingle.priority' => 'digits_between:1,5',
    ];

    public function setPriority(Post $postSingle, $priority)
    {
        $this->authorize('update', $postSingle);
        $this->postSingle->priority = $priority;
    }

}

在我的刀片视图中，我有 <button wire:click="setPriority({{ $postSingle->id }}, 4)"></button>

在其他地方我用{{ $postSingle->priority }}显示优先级

我不直接用wire:model="postSingle.priority"做模型属性绑定的原因是我想跑$this->authorize('update', $postSingle);。

下面的代码发生的情况是，如果我单击按钮，刀片视图中的$postSingle->priority 会更新，但我的数据库中的 Post 记录不会更新。我错过了什么？

您似乎忽略了实际保存记录。

public function setPriority(Post $postSingle, $priority)
{
    $this->authorize('update', $postSingle);
    $this->postSingle->priority = $priority;

    // save the record
    $this->postSingle->save();
}
