Question

我有Team有口才，有TeamObserver。 TeamObserver有deleting event，如果我打电话给TeamDeletingEvent。 TeamDeletingEvent分派TeamDeletingListener。如果TeamDeletingLister返回false会停止团队删除功能吗？

TeamObserver

class TeamObserver
{
    /**
     * Handle the team "deleting" event.
     *
     * @param  Team  $team
     * @return void
     */
    public function deleting(Team $team)
    {
        event(new TeamDeletingEvent($team));
    }
}

TeamDeletingEvent

class TeamDeletingEvent
{
    use SerializesModels;

    /**
     * @var Team
     */
    public $team;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct(Team $team)
    {
        $this->team = $team;
    }
}

TeamDeletingListener

class TeamDeletingListener
{
    /**
     * Handle the event.
     *
     * @param  TeamDeletingEvent  $event
     * @return bool
     */
    public function handle(TeamDeletingEvent $event)
    {
        $teamUser = Team::where('id', $event->team->id)->users()->first();
        if(is_null($teamUser)){
           return true;
        }
        return false;
    }
}

除了TeamObserver和AppServiceProvider Event and Listener中注册的EventServiceProvider

侦听器返回false不会停止删除功能。它将停止事件的连续侦听器调用。但是，雄辩的事件返回false将停止删除功能。（模型实例值已更新，但数据库中未更新）。更多信息Detail Answer
