在livewire中单击时刷新组件失败

Question

尝试了所有可能的解决方案来刷新组件，但失败了。有没有任何选项可以不推送新的注释并刷新$comments变量(无论它包含什么(？

想要在点击发送按钮时刷新$comments及其与刀片中回复的关系

在发送按钮上调用$refresh操作，但似乎不起作用。甚至尝试使用$this->重新渲染组件；render((。这也失败了。

<div>
@foreach($comments as $item)
<div class="row" @if($item->reply_id != null) style="margin-left:40px;" @endif>
<div class="col-md-12">
<div class="py-md-4 py-3 border_bottom" >
<div class="row">
<div class="col-md-1 col-sm-1 col-1">

由于没有更新任何属性，livewire聊天组件将不会刷新。

可能的解决方案不是将列表作为参数传递，而是在聊天组件中获取它。使用事件触发刷新：

@click="$emit('discussion.chat.{{ $id }}.refresh')"

frontend.discussion-chat内部有

public function listeners(): array
{
return [
"discussion.chat.$this->id.refresh" => "reload"
];
}
public function reload(): void
{
// E.g.
$this->comments->fresh();
}
