实现Laravel Eloquent模型事件-检查触发的事件

我遵循这个答案：

Laravel模型事件

我正在尝试实现标记答案的代码。

我认为每一个想法都是一样的"回答"；但它似乎并没有引爆这些事件。

如何检查事件是否正在启动？

这是我的型号：

<?php
namespace App;
use App'Traits'ModelEventThrower;
use Carbon'Carbon;
use Illuminate'Database'Eloquent'Model;
class Cuotas extends Model
{
    use ModelEventThrower;

    protected $fillable = [ 'apartamento_id','fecha_cuota','fecha_vencimiento', 'tipo_cuota_id', 'monto', 'descripcion_cuota','saldo'  ];
    protected $dates = ['created_at', 'updated_at', 'deleted_at','fecha_vencimiento','fecha_cuota'];
    protected $appends = ['tipo_cuota'];
    //protected static $othersEvents = ['saving'];

    function getTipoCuotaAttribute(){
        $id = $this->attributes['tipo_cuota_id'];
        $tipoCuota = TipoCuota::lists('descripcion_cuota','id')->toArray();
        return $tipoCuota[$id];
    }

    function getFechaVencimientoAttribute($value){
        return Carbon::parse($value)->format('d-m-Y');
    }
    function setFechaVencimientoAttribute($value){
        $this->attributes['fecha_vencimiento'] = Carbon::createFromFormat('d-m-Y', $value);
    }
    function getFechaCuotaAttribute($value){
        return Carbon::parse($value)->format('d-m-Y');
    }
    function setFechaCuotaAttribute($value){
        $this->attributes['fecha_cuota'] = Carbon::createFromFormat('d-m-Y', $value);
    }
    function apartamento()
    {
        return $this->belongsTo('App'Apartamentos', 'apartamento_id');
    }
    public function pagos(){
        return $this->hasMany('App'Pagos','cuota_id', 'id');
    }
}

这是我的特点：

<?php
namespace App'Traits;
use Illuminate'Database'Eloquent'Model;
use Illuminate'Support'Facades'Event;
/**
 * Class ModelEventThrower
 * @package App'Traits
 *
 *  Automatically throw Add, Update, Delete events of Model.
 */
trait ModelEventThrower {
    /**
     * Automatically boot with Model, and register Events handler.
     */
    protected static function bootModelEventThrower()
    {
        foreach (static::getModelEvents() as $eventName) {
            static::$eventName(function (Model $model) use ($eventName) {
                try {
                    $reflect = new 'ReflectionClass($model);
                    Event::fire(strtolower($reflect->getShortName()).'.'.$eventName, $model);
                } catch ('Exception $e) {
                    return true;
                }
            });
        }
    }
    /**
     * Set the default events to be recorded if the $recordEvents
     * property does not exist on the model.
     *
     * @return array
     */
    protected static function getModelEvents()
    {
        if (isset(static::$othersEvents)) {
            return static::$othersEvents;
        }
        return [
            'created',
            'updated',
            'deleted',
        ];
    }
} 

我的EventServiceProvider:

<?php
namespace App'Providers;
use Illuminate'Contracts'Events'Dispatcher as DispatcherContract;
use Illuminate'Foundation'Support'Providers'EventServiceProvider as ServiceProvider;
class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        'App'Events'SomeEvent' => [ 'App'Listeners'EventListener', ],
    ];
    /**
     * Register any other events for your application.
     *
     * @param  'Illuminate'Contracts'Events'Dispatcher  $events
     * @return void
     */
    public function boot(DispatcherContract $events)
    {
        parent::boot($events);
        $events->subscribe('App'Handlers'Events'CuotasEventHandler');
    }
}

我的事件处理程序：

<?php
namespace App'Handlers'Events;
use App'Cuotas;
class CuotasEventHandler{
    /**
     * Create the event handler.
     *
     * @return 'App'Handlers'Events'CuotasEventHandler
     */
    public function __construct()
    {
        //
    }
    /**
     * Handle cuotas.created event
     */
    public function created(Cuotas $cuotas)
    {
       dd('created');
    }
    /**
     * Handle cuotas.updated event
     */
    public function updated(Cuotas $cuotas)
    {
        //Implement logic
        dd('updated');
    }
    /**
     * Handle cuotas.deleted event
     */
    public function deleted(Cuotas $cuotas)
    {
        //Implement logic
        dd('deleted');
    }
    /**
     * @param $events
     */
    public function subscribe($events)
    {
        $events->listen('cuotas.created','App'Handlers'Events'CuotasEventHandler@created');
        $events->listen('cuotas.updated','App'Handlers'Events'CuotasEventHandler@updated');
        $events->listen('cuotas.deleted','App'Handlers'Events'CuotasEventHandler@deleted');
    }
}

当我在$Cuotas模型中更新、删除或创建新记录时，我看不出事件是否被触发。

我的意图是更新"；saldo"；（余额）列，使用在另一个称为"余额"的模型中已经完成的付款；帕戈斯"；。
