重新装载模型在laravel [英] Reloading model in laravel

问题描述

在我的一些测试中，我有一个我创建的用户模型，我运行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 ，这将重新填充数据库中的属性。

是有一个方法在laravel做到这一点？我读过api，找不到一个方法： http://laravel.com /api/4.1/Illuminate/Database/Eloquent/Model.html 有关正确方式的任何想法？

解决方案

我也看不到。看起来你必须：

  $ model = $ model-> find（$ model-> id）; 
  

您还可以自己创建一个：

  public function reload（）
 {
 $ instance = new static; 
 
 $ instance = $ instance-> newQuery（） - > find（$ this-> {$ this-> primaryKey}）; 
 
 $ this-> attributes = $ instance->属性; 
 
 $ this-> original = $ instance-> original; 
} 
  

只是在这里测试它，它看起来很有效，不知道这是多远但是，Eloquen是一个很大的班级。

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.

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?

解决方案

I can't see it either. Looks like you'll have to:

$model = $model->find($model->id);

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;
}

Just tested it here and it looks it works, not sure how far this goes, though, Eloquen is a pretty big class.
