如何从 Laravel 的数据库中重新加载/刷新模型?

How to reload/refresh model from database in Laravel?(如何从 Laravel 的数据库中重新加载/刷新模型?)

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，我通常会调用类似 user.reload 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关于正确"方法的任何想法?

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;
}

刚刚在这里测试过，看起来可以，但不确定这能走多远，不过，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.
