Livewire：添加新记录后无法更新子组件

Question

我有一个问题无法解决。我已经将组件结构设置为：

Post -> 评论 -> 评论回复

CommentReply 发出由 Post 捕获的事件。 Post 更新评论集合。

评论（模特）有自我关系作为回应。

现在如果评论是顶级的，视图就会更新。但是，如果响应关系已更新，则视图不会显示更新。如果我发出映射到 Comment（组件）中的 $refresh 的刷新事件，组件将抛出错误：

Uncaught (in promise) TypeError: Cannot read property 'fingerprint' of null

更新

CommentReply.php

public function post_reply () {
     ...
    $new_comment = $this->comment->response()->create($c);
    $this->is_replying = false;
    $this->emit('content:comments:replied', $new_comment);
}

Comment.php（组件）

    public $listeners = [
        'content:comments:replied' => 'replied'
    ];

   public function replied($comment) {
        /*
           received as array because type hinting
           created error of array to string conversion
       */
        $c = new CommentModel($comment); 
        $this->comment->responses->prepend($c);
    }

comment.blade.php

<div>
@foreach($comment->responses as $response)
<div>
     <div>
         {{ $response->comment }}
     </div>

     <livewire:comment-reply :comment="$comment" :key="'comment-' . $response->id" />
</div>
@endforeach
</div>

comment-reply.blade.php

<div x-data="{ replying: @entangle('is_replying') }">
    <button @click="replying = true;" x-show="!replying">Reply</button>
   <div x-show="replying">
       <textarea wire:model.defer="c.comment"></textarea>
       <button wire:click="post_reply">Post</button>
    </div>
</div>

Answer 1

这就是我的处理方式...

创建了一个组件CommentView并将评论显示逻辑移至该组件 comment-view.blade.php

<div>
     <div>
         {{ $comment->comment }}
     </div>

     <livewire:comment-reply :comment="$comment" />
</div>

Comment 组件现在有两个变量，$comment 和 $responses，每次 CommentReply 发出 content:comments:replied 和 $responses变量被刷新。

Comment.php

    public $listeners = [
        'content:comments:replied' => 'replied'
    ];

   public function replied() {
        $this->responses = $this->comment->responses()->orderBy('created_at', 'desc')->get();
    }

comment.blade.php

<div>
    <livewire:comment-view :comment="$comment" />
    @foreach($responses as $r_comment) 
          <livewire:comment-view :comment="$r_comment" :key="'response-' . $r_comment->id" />
     @endforeach
</div>
