Hi there,

is it possible to have a dataobject inside a dataobject?

My first dataobject is for products and i want to include another for tier prices inside the first.

Can someone tell me how to do this?!

Thx in advance.

Hi cSGermany,

It is possible to nest Dataobjects inside of dataobjects. You can do this just like you would add a dataobject to your Page. For example

Product.php class

class Products extends DataObject {

public static $has_many=array(
'TierPrices'=>'TierPrice'
);

public function getCMSFields(){
return new FieldList(
new GridField('TierPrices','Tier Price', $this->TierPrices(), GridFieldConfig_RecordEditor::Create())
);

}

}

TierList.php class

class TierList extends DataObject {

public static $db=array(
'Price'=>'Int'
);

public static $has_one=array(
'Parent'=>'Product'
);

public function getCMSFields(){
return new FieldList(
new TextField('Price')
);

}

}

Hope that helps.

Hi IOTI,

thank you it works. But the grid shows only "ID".

I usually call my Grid fields like this

$fields->addFieldToTab('Root.Auftraege', GridFieldBase::getGridField('Auftraege', _t('Dict.ORDERS', 'Auftraege'), $this->Orders()));

GridFieldBase.php

<?php

class GridFieldBase {
    
    static public function getGridField($__name, $__label, $__storage, $__numItemsPerPage = 32, $__sortID = true) {
        
        $gridFieldConfig = GridFieldConfig::create();
        $gridFieldConfig->addComponents(
            new GridFieldToolbarHeader(),
            new GridFieldAddNewButton('toolbar-header-right'),
            new GridFieldSortableHeader(),
            new GridFieldDataColumns(),
            new GridFieldPaginator($__numItemsPerPage),
            new GridFieldEditButton(),
            new GridFieldDeleteAction(),
            new GridFieldDetailForm()
        );
        
        if($__sortID) {
            
            $gridFieldConfig->addComponents(
                new GridFieldSortableRows('SortID')
            );
            
        }
        
        return new GridField($__name, $__label, $__storage, $gridFieldConfig);
        
    }
    
}

How can I use this for the actual case?

Thx in advance

If you want to control which fields appear in the grid you should use the static $summary_fields array on your dataobject. For example

class Product extends DataObject {
public static $db=array(
'Title'=>'Text',
'Category'=>'Text',
'Size'=>'Text'
);

public static $summary_fields=array(
'Title'=>'Title',
'Category'=>'Product Category'
);
}

Oh damn it, such a stupid mistake from me :D

Thanks :)
