has_many Example
=================
Please note this example is written with 3.0.x in mind, if you are using 3.1.x make sure you scope all static properties to private not public.
```php
/*** TestPage.php ***/
class TestPage extends Page {
public static $has_many=array(
'TestObjects'=>'TestObject'
);
public function getCMSFields() {
$fields=parent::getCMSFields();
$conf=GridFieldConfig_RelationEditor::create(10);
$conf->addComponent(new GridFieldSortableRows('SortOrder'));
$fields->addFieldToTab('Root.TestObjects', new GridField('TestObjects', 'TestObjects', $this->TestObjects(), $conf));
return $fields;
}
}
/*** TestObject.php ***/
class TestObject extends DataObject {
public static $db=array(
'Title'=>'Text',
'SortOrder'=>'Int'
);
public static $default_sort='SortOrder';
}
```
