laravel how to call a method when a row inserted in model? - laravel

Question

I have two model (Cart & AcceptedCart) and I want to run this method when a row insrted in AcceptedCart model :
public function dataUpdated()
{
$cart = Cart::where('id' , $this->cart_id)->first();
$sum = 0;
$acceptedCarts = AcceptedCart::where('cart_id' , $this->cart_id)->get();
foreach($acceptedCarts as $acceptedCart){
$sum += $acceptedCart->accepted_count;
}
if ($sum == $cart->product_quantity){
$cart->full_accepted = true;
$cart->save();
}
}
as you see, I change full_accpted = true in the cart model.
the AcceptedCart migration is :
public function up()
{
Schema::create('accepted_carts', function (Blueprint $table) {
$table->id();
$table->unsignedBigInteger('cart_id');
$table->unsignedBigInteger('accepted_by')->nullable();
$table->integer('accepted_count');
$table->timestamps();
$table->foreign('cart_id')->references('id')->on('carts');
});
}
and Cart migration is :
public function up()
{
Schema::create('carts', function (Blueprint $table) {
$table->id();
$table->boolean('full_accepted')->default(false);
$table->text('address');
$table->timestamps();
});
}
how can I call this dataUpdated method every time a row inserted to AcceptedCart model?

Answer 1

You can use the models booted() method to achieve this simple task, also you can use the separate observer class to listen to model events like created/updated/deleted, etc.
E.g. 1. How you can listen to model events in the same model.
class AcceptedCart extends Model
{
/**
* The "booted" method of the model.
*
* #return void
*/
protected static function booted()
{
static::created(function ($acceptedCart) {
$acceptedCart->dataUpdated();
});
// Similarly you can do for updated/deleted events as well
}
}
E.g. 2. You can use Observer class to listen to events
<?php
namespace App\Observers;
use App\Models\AcceptedCart;
class AcceptedCartObserver
{
/**
* Handle the AcceptedCart "created" event.
*
* #param \App\Models\AcceptedCart $acceptedCart
* #return void
*/
public function created(AcceptedCart $acceptedCart)
{
$acceptedCart->dataUpdated();
}
/**
* Handle the AcceptedCart "updated" event.
*
* #param \App\Models\AcceptedCart $acceptedCart
* #return void
*/
public function updated(AcceptedCart $acceptedCart)
{
// Similarly for update
}
}

Answer 2

You might want to consider using Observers.
Events can be fired when a Model is created/updated and so on.
