Config Loading Issue: ‘connection on null’ Error in Laravel

[sajadsdi]

Laravel Version

10.37.1

PHP Version

8.1.13

Database Driver & Version

MySQL 5.7

Description

This error occurs because all configs are loaded at the start of Laravel’s boot process, which creates a limitation for using the configs in Laravel. I have resolved this issue in a pull request at the link below, but I think I did not communicate my point well and it got rejected.

pull requests : #49313

Please advise if you have a better solution to this problem!

Please don’t close this issue quickly; let’s discuss it further as it is very important to me.

Steps To Reproduce

Installation of the laravel-setting-pro package.

I wrote this package myself and am completely confident in it!
GitHub package link: https://github.com/sajadsdi/laravel-setting-pro

Before installation, we deactivate optimization!

php artisan optimize:clear

• Now we install the package!

composer require sajadsdi/laravel-setting-pro
php artisan setting:publish
php artisan setting:install

• After installation, we test the package by executing these commands in a test controller:

<?php

namespace App\Http\Controllers;

class TestController extends Controller
{
    public function test()
    {
        dd(setting('test','welcome'), setting('test','version'));
    }
}

• After creating a test route (e.g., http://127.0.0.1:8000/test), we boot up the server.

php artisan serve

• We bring up the test route in the browser, and the result we receive is:

"welcome to Laravel Setting Pro" // app\Http\Controllers\TestController.php:10
"1.0.0" // app\Http\Controllers\TestController.php:10

• So far everything goes very well, then we close the server!

Ctrl + C on terminal

• We boot it up again.

php artisan serve

• We see everything is normal! We close the server again.

Ctrl + C on terminal

• Now we create a config file named custom.php and save it as follows:

<?php

return [
    "massage" => setting('welcome'),
    "version" => setting('test', 'version')
];

• We serve Laravel.

php artisan serve

And we encounter this error!

In Model.php line 1819:

Call to a member function connection() on null

And here is the laravel.log file
