Hi experts,
I'm extending a product page via DataExtension

class ProductPropertiesExtension extends DataExtension {
private static $has_many = array(
'Accessories' => 'ProductAccessory'

with Accessory.php

class ProductAccessory extends DataObject {
private static $db = array(
'ProductID' => 'Int'
private static $has_one = array(
'Product' => 'Product'

The table ProductAccessory is created.

Then I try to add a grid field in my extension class with:
(the GridField is not yet configured correctly, it's just a test)

public function updateCMSFields(FieldList $fields) {
      // Create a default configuration for the new GridField, allowing record editing
$config = GridFieldConfig_RelationEditor::create();
// Set the names and data for our gridfield columns
'Title' => 'Title'
// Create a gridfield to hold the accessory relationship
$accessoriesField = new GridField(
'Accessories', // Field name
'Product', // Field title
$this->Accessories(), // List of all related accessories
// Create a tab named "Accessories" and add our field to it
$fields->addFieldToTab('Root.Accessories', $accessoriesField);

But then I get the error:
Call to undefined method ProductPropertiesExtension::Accessories() in /Applications/XAMPP/xamppfiles/htdocs/swipestripe-funds/code/Product.php on line 352

What am I doing wrong?

TIA Stephan

Try $this->owner->Accessories() rather than $this->Accessories()
