Laravel - Eager loaded model function

Question

I am trying to build some chat system using Laravel and i have these 2 models: User and Thread

The User model has Messagable Trait where you can get all the threads with

$user->threads();

I am trying to eager load additional data to the threads array using the following:

$threads = Auth::user()->threads()->with(['participants.user'])->get();

What i am struggling is the Threads model has function to get the latest message from it:

$thread->getLatestMessage();

My question is how can i append this latest message to the upper query i am doing. I was trying something like this but its not ok... I guess im doing something stupid here...

$threads = Auth::user()->threads()->with([
        'participants.user',
        'latestMessage' => function ($query) {
            return $query->getLatestMessageAttribute();
        }])->get();

or

$threads = Auth::user()->threads()->with(['participants.user','getLatestMessageAttribute'])->get();

I hope i clarified this ok because i am using a 3rd party package for this system which has these Traits and Thread classes i am using.

SOLUTION

Looks like i had to add append('accessor_name') at the end when getting the collection.

$collection = Auth::user()->relationship()->get()->append('accessor_name');

Answer 1

You can override class .Create new model and extend package model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;


class Thread extends \Lexx\ChatMessenger\Models\Thread
{
    use HasFactory;

    protected $appends=['latest_message'];
    

}

Publish config:

php artisan vendor:publish --provider="Lexx\ChatMessenger\ChatMessengerServiceProvider" --tag="config"

in config/chatmessenger.php

'thread_model' => \App\Models\Thread::class,

Updated If anyone still not getting get attribute data then dont forget to clear cache

php artisan cache:clear

php artisan optimize

php artisan config:clear

php artisan clear
