Livewire Error: public property [message] must be of type: [numeric, string, array, null, or boolean]

Question

我遇到了这个问题，但我不明白我做错了什么，因为我对这个网站上的另一个组件采用了同样的方法，并且工作得很好....

ViewMessages.php

public $messages;

public function mount($messages)
    {
        $this->messages = $messages;
    }

查看-messages.blade.php

<div class="flex flex-col">
        @foreach ($messages as $message)
                {{$message->content}}
        @endforeach
</div>

一切正常，并正确输出所有消息。

当我尝试将 livewire 组件传入 for each 时，它给出了该错误。

@foreach ($messages as $message)
       @livewire('chat.show-message', ['message'=>$message], key('show-message-'.$message->id))
@endforeach

// ShowMessage.php
public $user;
    public $message;
    public $user_id;
    public $content;
  

    public function mount($message)
    {
        $this->message = $message;
    }

老实说，我对自己做错了什么感到困惑，因为我复制了完全相同的代码并更改了我之前使用的变量。当我做嵌套组件时，它现在可以在网站上运行。

<div class="flex flex-col space-y-4 py-4 overflow-y-auto">
     @foreach ($chats as $chat)
          @livewire('kanbans.show-sidebar-chat-message', ['chat'=>$chat], key('chat-'.$chat->id))
     @endforeach
</div>

我已经重写了这个组件两次，没有发现任何语法问题或拼写错误。 =/

问题出在 DB Facade 查询上

$messages = DB::select('SELECT * FROM chat_messages 
         WHERE (receiver_id = :auth_id and user_id = :user) OR (receiver_id = :user2 AND user_id = :auth_id2)',
   ['auth_id' => $auth_id, 'user' => $user->id, 'auth_id2' => $auth_id, 'user2' => $user->id]);

虽然还不确定如何传入 $user->id 但是当我将用户 ID 设置为 #2 时，livewire 组件会按预期工作。

public function view($user)
    {
        $user=User::where('id',$user)->firstOrFail();

        $messages = ChatMessage::where(function ($query){
                                $query->where('user_id', '=', auth()->id() )
                                        ->where('receiver_id', '=', 2 );
                                })->orWhere(function ($query){
                                    $query->where('user_id', '=', 2)
                                        ->where('receiver_id', '=', auth()->id() );
                                    })->get();
        
        return view('backend.chat.view-contact-chat',compact('user','messages'));
    }
