Php Laravel 4雄辩模型观察者事件的顺序

根据，创建新项时将触发以下事件。创建，然后创建，然后保存，然后保存

然而，当我调用一个模型类时，事件是以相反的方式触发的。在创建之前调用保存

我的代码：

class TBone extends Eloquent {

    protected $table = 'bone';

    protected $primaryKey = 'id';

    protected $guarded = array('id');

}

class ObserverLeBone{

    public function creating($bone)
    {
        echo "creating\r\n";
    }

    public function saving($bone) 
    {
        echo "saving\r\n";
    }

    public function updating($bone) 
    {
        echo "updating\r\n";
    }
}

class EloquentTest extends TestCase {

    public function testObserver()
    {
       TBone::observe(new ObserverLeBone());
       $attributes = array('appreciatedAs' => 'Steak'); 
       TBone::create($attributes);
    }

}

saving
creating

观察者类：

class TBone extends Eloquent {

    protected $table = 'bone';

    protected $primaryKey = 'id';

    protected $guarded = array('id');

}

class ObserverLeBone{

    public function creating($bone)
    {
        echo "creating\r\n";
    }

    public function saving($bone) 
    {
        echo "saving\r\n";
    }

    public function updating($bone) 
    {
        echo "updating\r\n";
    }
}

class EloquentTest extends TestCase {

    public function testObserver()
    {
       TBone::observe(new ObserverLeBone());
       $attributes = array('appreciatedAs' => 'Steak'); 
       TBone::create($attributes);
    }

}

saving
creating

测试：

class TBone extends Eloquent {

    protected $table = 'bone';

    protected $primaryKey = 'id';

    protected $guarded = array('id');

}

class ObserverLeBone{

    public function creating($bone)
    {
        echo "creating\r\n";
    }

    public function saving($bone) 
    {
        echo "saving\r\n";
    }

    public function updating($bone) 
    {
        echo "updating\r\n";
    }
}

class EloquentTest extends TestCase {

    public function testObserver()
    {
       TBone::observe(new ObserverLeBone());
       $attributes = array('appreciatedAs' => 'Steak'); 
       TBone::create($attributes);
    }

}

saving
creating

运行测试用例时的输出：

class TBone extends Eloquent {

    protected $table = 'bone';

    protected $primaryKey = 'id';

    protected $guarded = array('id');

}

class ObserverLeBone{

    public function creating($bone)
    {
        echo "creating\r\n";
    }

    public function saving($bone) 
    {
        echo "saving\r\n";
    }

    public function updating($bone) 
    {
        echo "updating\r\n";
    }
}

class EloquentTest extends TestCase {

    public function testObserver()
    {
       TBone::observe(new ObserverLeBone());
       $attributes = array('appreciatedAs' => 'Steak'); 
       TBone::create($attributes);
    }

}

saving
creating

所以我只是想知道为什么在创建事件之前触发saving事件？

---

还是我遗漏了什么？

不确定这是错误还是功能，但根据代码，create调用save，您是对的：

public static function create(array $attributes)
{
    $model = new static($attributes);

    $model->save();

    return $model;
}

然后保存触发事件：

public function save(array $options = array())
{
    $query = $this->newQueryWithDeleted();

    // If the "saving" event returns false we'll bail out of the save and return
    // false, indicating that the save failed. This gives an opportunities to
    // listeners to cancel save operations if validations fail or whatever.
    if ($this->fireModelEvent('saving') === false)
    {
        return false;
    }

            ....

执行之前，插入（创建）：

触发创建事件

if ($this->fireModelEvent('creating') === false) return false;

是的，这更像是一个术语集群。我猜想。创建意味着在内存中创建一些东西。保存意味着在数据库中插入一些内容。而laravel似乎使用术语create作为“插入”。但是“更新”毫无意义。现在，我必须将逻辑放入保存事件处理程序中，以确定对象是否已被持久化，我认为这是不必要的，因为我有一个正在创建的事件。。。所以是的，没有虫子只是一种解释。。。
