问题描述
在我的一些测试中，我创建了一个用户模型，并运行了一些需要保存某些属性的方法.在 Rails 中，我通常会调用诸如 user.reload 之类的东西，它会重新填充数据库中的属性.
In some of my tests, I have a user model I have created and I run some methods that need to save certain attributes. In rails, I would typically call something like user.reload which would repopulate the attributes from the database.
laravel 有没有办法做到这一点?我通读了 api 并找不到它的方法:http://laravel.com/api/4.1/Illuminate/Database/Eloquent/Model.html 任何关于正确"方法的想法?
Is there a way in laravel to do that? I read through the api and couldn't find a method for it: http://laravel.com/api/4.1/Illuminate/Database/Eloquent/Model.html Any ideas on the "right" way to do this?
推荐答案
我也看不到.看起来你必须:
I can't see it either. Looks like you'll have to:
$model = $model->find($model->id);
您也可以自己创建一个:
You can also create one yourself:
public function reload()
{
$instance = new static;
$instance = $instance->newQuery()->find($this->{$this->primaryKey});
$this->attributes = $instance->attributes;
$this->original = $instance->original;
}
刚刚在这里测试了它，它看起来有效，但不确定这能走多远，Eloquen 是一个相当大的类.
Just tested it here and it looks it works, not sure how far this goes, though, Eloquen is a pretty big class.
