Laravel中的填充方法不起作用? [英] Fill method in Laravel not working?

问题描述

我正在学习如何使用Laravel框架，但是在填充模型时遇到了麻烦.这是我的代码:

I am learning how to use Laravel framework but I am having troubles with filling a Model. Here is my code:

模型Event:

<?php
class Event extends Eloquent {
  //Some functions not used yet
}

这是控制器中的代码:

$event = new Event();
$event->fill(array('foo', 'bar'));
print_r($event->attributes);

那么，为什么print_r显示一个空数组?

So, why the print_r is displaying an empty array?

推荐答案

属性是受保护的财产.使用 $ obj-> getAttributes()方法.

The attributes is a protected property. Use $obj->getAttributes() method.

实际上.首先，您应该将模型名称从Event更改为其他名称，Laravel的Facade类为Illuminate\Support\Facades\Event，因此可能是一个问题.

Actually. at first you should change the model name from Event to something else, Laravel has a Facade class as Illuminate\Support\Facades\Event so it could be a problem.

关于fill方法，您应该将关联数组传递给fill方法，例如:

Regarding the fill method, you should pass an associative array to fill method like:

$obj = new MyModel;
$obj->fill(array('fieldname1' => 'value', 'fieldname2' => 'value'));

还要确保您声明了protected $fillable(检查质量分配)属性在Model中使用允许填充的属性名称.初始化Model时，您也可以做同样的事情:

Also make sure you have a protected $fillable (check mass assignment) property declared in your Model with property names that are allowed to be filled. You may also do the same thing when initializing the Model:

$properties = array('fieldname1' => 'value', 'fieldname2' => 'value');
$obj = new ModelName($properties);

最后，致电:

// Instead of attributes
dd($obj->getAttributes());

因为attributes是受保护的属性.
