kohana property error

i have a kohana module, describing a table that has a reference to another table. So i declare in the 'Sale' module:

protected $_belongs_to = array(
    'image'     => array('foreign_key' => 'sale_picture_header'),
);

and then, in a get method, i say:

 public function __get($property)
{
blah blah
     .......
     if ($property == 'image')
    {
        ret开发者_高级运维urn $this->image; 
    }

and then i call in a view

                <? $image = $sale->image->find(); ?>

but i get a weird error :

Notice: Undefined property: Model_Sale::$image in ...

(in the model) where i declare $this-> image (so it doesn't actually recognise this property an i wonder why)

why is that? the property is defined. am i missing something?

thank you!

Assuming your question is about ORM models

There is no need to modify __get() method, because ORM will automatically return table columns and relations by their names. Just use $sale->image (without ->find()) and you get a related model.
