Non-static wrapper for Magento's Mage class
Testing is fun, but not when static classes are everywhere in your code! Use Mage Wrapper as a replacement for Mage static calls.
class Foo_Bar_Model_Baz extends Mage_Core_Model_Abstract
{
// ...
public function getSomeProduct($id)
{
return $this->mage->getModel('catalog/product')->load($id);
}
// ...
}You must ensure that $this->mage resolves to an instance of Mage_Wrapper yourself. The simplest solution is to implement _construct and set it there:
class Foo_Bar_Model_Baz extends Mage_Core_Model_Abstract
{
// ...
protected function _construct()
{
$this->mage = new Mage_Wrapper();
parent::_construct();
}
// ...
}However, such techniques mean that your Mage_Wrapper dependency cannot be mocked, so the author recommends a setter:
class Foo_Bar_Model_Baz extends Mage_Core_Model_Abstract
{
protected $mage;
// ...
protected function _construct()
{
$this->setMage(new Mage_Wrapper());
parent::_construct();
}
public function setMage(Mage_Wrapper $mage)
{
$this->mage = $mage;
}
// ...
}Have fun!
