我下面这样的回答：实施Laravel雄辩模型事件 - 检查引发的事件
而且我想实现显着的答案代码。
我认为everythink就像“答案”一样，但它似乎并没有触发事件。
如何检查事件是否正在发射？
这是我的模型：
<?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');
}
}
这是我的特质：
<?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\[email protected]');
$events->listen('cuotas.updated','App\Handlers\Events\[email protected]');
$events->listen('cuotas.deleted','App\Handlers\Events\[email protected]');
}
}
当我更新，删除或在模型$ Cuotas中创建一条新记录，我不能看到事件是否被解雇。
我的意图是更新模型的“saldo”（余额）列，使用已在其他模型中完成的付款，名为“pagos”。
