Laravel-创建模型启动不触发

Question

我希望在$protected $foo事件中为'foo'分配static::creating，但是当我输出最终对象时，该属性为null。该事件似乎没有触发:

namespace App;

use Illuminate\Database\Eloquent\Model;

class Item extends Model {

    protected $foo;

    public static function boot() {
        parent::boot();
        static::creating(function (Item $item) {
            echo "successfully fired";   //this does not get echoed
            $item->foo = 'foo';
        });
    }
}

我究竟做错了什么？

您的代码运行正常，我以此方式进行了最终测试

在模型中

protected $foo;

public static function boot() {
    parent::boot();

    //while creating/inserting item into db  
    static::creating(function (AccountCreation $item) {
        echo "successfully fired";   
        $item->foo = 'fooasdfasdfad'; //assigning value
    });

    //once created/inserted successfully this method fired, so I tested foo 
    static::created(function (AccountCreation $item) {
        echo "<br /> {$item->foo} ===== <br /> successfully fired created";   
    });
}

Controller 中的

AccountCreation::create(['by'=>'as','to'=>'fff','hash'=>'aasss']);

浏览器中的，收到此响应

successfully fired
fooasdfasdfad =====
successfully fired created
