Laravel 7.x Observer not saving, created_by updated_by user - laravel

Question

I have a Model named "Resource".
by using this command
php artisan make:observer ResourceObserver --model=Resource
this command create a new file, i update created, updated functions and update constructor
<?php
namespace App\Observers;
use App\Resource;
class ResourceObserver
{
protected $userID;
public function __construct()
{
$this->userID = auth()->user()->id;
}
/**
* Handle the resource "created" event.
*
* #param \App\Resource $resource
* #return void
*/
public function created(Resource $resource)
{
$resource->created_by = $this->userID;
}
/**
* Handle the resource "updated" event.
*
* #param \App\Resource $resource
* #return void
*/
public function updated(Resource $resource)
{
$resource->updated_by = $this->userID;
}
/**
* Handle the resource "deleted" event.
*
* #param \App\Resource $resource
* #return void
*/
public function deleted(Resource $resource)
{
//
}
/**
* Handle the resource "restored" event.
*
* #param \App\Resource $resource
* #return void
*/
public function restored(Resource $resource)
{
//
}
/**
* Handle the resource "force deleted" event.
*
* #param \App\Resource $resource
* #return void
*/
public function forceDeleted(Resource $resource)
{
//
}
}
this is my migration:
public function up()
{
Schema::create('resources', function (Blueprint $table) {
$table->id();
// some fields here
$table->foreignId('created_by')->nullable()->default(null)->constrained('users')->onDelete('set null');
$table->foreignId('updated_by')->nullable()->default(null)->constrained('users')->onDelete('set null');
$table->timestamps();
});
}
then you should register the observer in AppServiceProvider like this:
use App\Observers\ResourceObserver;
use App\Resource;
public function boot()
{
Schema::defaultStringLength(191);
Resource::observe(ResourceObserver::class);
}
Now the problem appears when update any record it is not save the user_id
to update i use update function in ResourceController
public function update(Request $request, Resource $resource)
{
$validations = [
// some validations
];
$request->validate($validations);
try {
if (!empty($resource)) {
$resource->field_a = $request->field_a;
$resource->field_b = $request->field_b;
$resource->field_c = $request->field_c;
$resource->save();
return 'done messge';
} else {
return 'error message';
}
} catch (\Exception $e) {
return 'bug message';
}
}
Any help please?!

Answer 1

When issuing a mass update or delete via Eloquent, the saved, updated, deleting, and deleted model events will not be fired for the affected models. This is because the models are never actually retrieved when issuing a mass update or delete.
So, In ResourceObserver i just changed from method from updated to updating,
and created to creating
