Laravel中的自定义设置器和获取器

Question

Here's a tricky question.

I am building a framework in Laravel and I want my objects to interact with Rackspace in a transparent way. From now on I made it possible to upload/delete objects without having in mind Rackspace

$model->file = Input::file('thing'); // and it uploads to Rackspace.

The next step I want to achieve is to get the route using my config file. The behaviour would be something like $route = $file->source (with source with hello.jpg in the database for instance) and get $route as rackspace.com/WHATEVER/hello.jpg. The part rackspace.com/WHATEVER is in my config file, so the only thing I need is how to make this behaviour.

I have been searching extensively and I only found the __call() method to do so. The fields I want to behave like this are dynamic and are setted from an array such as:

public static $rackspaceable = array('source' => 'images-demo');

Where images-demo is a Rackspace container.

Does anyone knows to achieve that and if it is even possible?

This might be what you are looking for:

class Model extends Eloquent {

    public static $rackspaceable = array('source' => 'images-demo');

    public function __get($key)
    {
        if (isset(static::$rackspaceable[$key]))
        {
            return static::$rackspaceable[$key];
        }

        return parent::__get($key);
    }

    public function __set($key, $value)
    {
        if (isset(static::$rackspaceable[$key]))
        {
            static::$rackspaceable[$key] = $value;
        }
        else
        {
            parent::__set($key, $value);
        }
    }
}

To use it:

$model = new Model;

var_dump( $model->source );

$model->source = 'new value';

var_dump( $model->source );
