Laravel - Model boot creating not firing
提问by bsapaka
I would like $protected $footo be assigned 'foo'in the static::creatingevent, but when I output the final object, the property is null. The event does not seem to fire:
我想在事件中$protected $foo赋值，但是当我输出最终对象时，该属性为空。该事件似乎没有触发：'foo'static::creating
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';
});
}
}
What am I doing wrong?
我究竟做错了什么？

Your code is working fine, I tested at my end in this way
您的代码运行良好，我以这种方式在最后进行了测试
In Model
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";
});
}
in Controller
在控制器中
AccountCreation::create(['by'=>'as','to'=>'fff','hash'=>'aasss']);
in browser, got this response
在浏览器中，得到这个响应
successfully fired
fooasdfasdfad =====
successfully fired created
