Sorting on Extension classes

[silverstripesk]

Hallo,

im trying to sort many_many related data. Your code works great if I add relation to Page.php directly, but not, if i add the relation to Extension class which is extending Page class... :(
I think many_many_extraFields are not found :(

Regards

Pali

This sounds like a deficiency in the core of SilverStripe that said I will test this when I can. Just to be sure ;)

What version of SilverStripe were you using?

Is your extension extending DataExtension? or just Extension? The reason I ask is I just tried a test and it seemed to work as expected for me using the git master of SortableGridField and SS 3.0.3 stable.

This was my setup:

TestPage.php

<?php
class TestPage extends Page {
    public static $many_many=array(
                            'TestObjects'=>'TestObject'
                        );


    public function getCMSFields() {
        $fields=parent::getCMSFields();

        $fields->addFieldToTab('Root.TestObject', $grid=new GridField('TestObjects', 'Test Objects', $this->TestObjects(), GridFieldConfig_RelationEditor::create(10)));
        $grid->getConfig()->addComponent(new GridFieldSortableRows('SortOrder'));

        return $fields;
    }

    public function TestObjects() {
        return $this->getManyManyComponents('TestObjects')->sort('SortOrder');
    }
}
class TestPage_Controller extends Page_Controller {}
?>

TestObject.php

<?php
class TestObject extends Dataobject {
    public static $db=array(
                    'Title'=>'Varchar'
                );

    public static $belongs_many_many=array(
                                    'TestPages'=>'TestPage'
                                );

    public function getCMSFields() {
        return new FieldList(
                        new TextField('Title', 'Title')
                    );
    }
}
?>

TestPageExtension.php

<?php
class TestPageExtension extends DataExtension {
    public static $many_many_extraFields=array(
                                    'TestObjects'=>array(
                                                    'SortOrder'=>'Int'
                                                )
                                );
}
?>

_config.php

Object::add_extension('TestPage', 'TestPageExtension');

hi, im defining relation in DataExtension too... I tested your example in my situation and it works well!

Thanks Ed!

<?php
class TestPageExtension extends DataExtension {
    public static $many_many_extraFields=array(
        'TestObjects'=>array(
            'SortOrder'=>'Int'
        )
    );


    public static $many_many=array(
        'TestObjects'=>'TestObject'
    );


    public function updateCMSFields(FieldList $fields) {

        $fields->addFieldToTab('Root.TestObject', $grid=new GridField('TestObjects', 'Test Objects', $this->owner->TestObjects(), GridFieldConfig_RelationEditor::create(10)));
        $grid->getConfig()->addComponent(new GridFieldSortableRows('SortOrder'));

    }

    public function TestObjects() {
        return $this->owner->getManyManyComponents('TestObjects')->sort('SortOrder');
    }
}
?>
