Fill method in Laravel not working?
提问by marc_aragones
I am learning how to use Laravel framework but I am having troubles with filling a Model. Here is my code:
我正在学习如何使用 Laravel 框架，但在填充模型时遇到了麻烦。这是我的代码：
The model Event:
型号Event：
<?php
class Event extends Eloquent {
//Some functions not used yet
}
And here is the code in the controller:
这是控制器中的代码：
$event = new Event();
$event->fill(array('foo', 'bar'));
print_r($event->attributes);
So, why the print_ris displaying an empty array?
那么，为什么print_r显示一个空数组呢？

The attributesis a protected property. Use $obj->getAttributes()method.
该属性是受保护的财产。使用$obj->getAttributes()方法。
Actually. at first you should change the model name from Eventto something else, Laravelhas a Facadeclass as Illuminate\Support\Facades\Eventso it could be a problem.
实际上。首先，您应该将模型名称从Event其他名称更改为其他名称，因为它Laravel有一个Facade类，Illuminate\Support\Facades\Event所以这可能是一个问题。
Regarding the fillmethod, you should pass an associative array to fillmethod like:
关于该fill方法，您应该将关联数组传递给fill方法，例如：
$obj = new MyModel;
$obj->fill(array('fieldname1' => 'value', 'fieldname2' => 'value'));
Also make sure you have a protected $fillable(check mass assignment) property declared in your Modelwith property names that are allowed to be filled. You may also do the same thing when initializing the Model:
还要确保您在您的属性中声明了一个protected $fillable（检查质量分配）属性Model，并使用允许填充的属性名称。你也可以在初始化时做同样的事情Model：
$properties = array('fieldname1' => 'value', 'fieldname2' => 'value');
$obj = new ModelName($properties);
Finally, call:
最后，调用：
// Instead of attributes
dd($obj->getAttributes());
Because attributesis a protected property.
因为attributes是受保护的财产。

Also make sure that the $fillable property is defined in your model class. For example, in your new renamed model:
还要确保在模型类中定义了 $fillable 属性。例如，在您的新重命名模型中：
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = ['field1', 'field2'];
If you do not have either $fillable or $guarded defined on your Model, fill() won't set any values. This is to prevent the model from mass assignment. See "Mass Assignment" on the Laravel Eloquent docs: http://laravel.com/docs/5.1/eloquent.
如果您没有在模型上定义 $fillable 或 $guarded，fill() 将不会设置任何值。这是为了防止模型进行质量分配。请参阅 Laravel Eloquent 文档中的“批量分配”：http://laravel.com/docs/5.1/eloquent 。
When filling the attributes, make sure to use an associative array:
填充属性时，请确保使用关联数组：
$event->fill(array('field1' => 'val1', 'field2' => 'val2'));
A useful way to debug and check all your values:
调试和检查所有值的有用方法：
//This will var_dump the variable's data and exit the function so no other code is executed
dd($event);
Hope this helps!
希望这可以帮助！

Use a key/value array in fill:
使用键/值数组填充：
An example:
一个例子：
$book->fill(array(
'title' => 'A title',
'author' => 'An author'
));
回答by Chando
In your model you need to have protected $fillable = ['foo','bar'];
在你的模型中，你需要有protected $fillable = ['foo','bar']；
Then you can do:
然后你可以这样做：
$event = new Event(array('foo' => "foo", "bar" => "bar"));
$event->save(); // Save to database and return back the event
dd($event);
The array key needs to be on the $fillable, as Laravel will effectively call:
数组键需要在 上$fillable，因为 Laravel 会有效地调用：
foreach ($array as $key => $value){
$event->$key = $value;
}
Alternatively, you can write directly to a column name:
或者，您可以直接写入列名：
$event = new Event();
$event->foo = "foo";
$event->bar = "bar";
$event->save();
dd($event);
