hello
I got few guestions about gridfield and creating new dataobject there

I want create photogallery for article pages so I got this code

class ArticlePhoto extends DataObject
{
	public static $singular_name = 'Obrázok k článku';
	
	public static $db = array (
		'Title' => 'text'
	);
	
	public static $has_one = array (
		'Image' => 'Image',
		'Page' => 'Page',
		);
}

class Article extends Page
{

	public static $has_many = array(
		'ArticlePhotos' => 'ArticlePhoto'
	);
	
	public function getCMSFields()
	{
		$f = parent::getCMSFields();
		
		$dl = DataList::create('ArticlePhoto')
			->where('PageID ='.$this->ID);
		
		$config = new GridFieldConfig_RelationEditor();
				
		$gridField = new GridField('ArticlePhotos','ArticlePhotoGallert', $dl,$config);
				
		$f -> addFieldToTab('Root.PhotoGallery', $gridField);
		return $f;
	}
}

I want use this DataObject for more page subclasses so for that is is in has_one Page class

it looks like really simple code but my probles is how to set automatically dataobject has_one page

when I create new dataobject this is not automatically set and I am redirected to page with ID = 1
when I delete filter '->where('PageID ='.$this->ID);' everything works fine but I still have to set this relation

I want just create DataObject and then upload Image without set this relation
any suggestions???

Noticed a typo in your code, ArticlePhotoGallert - should this be ArticlePhotoGallery?

This is a problem I have too. There doesn't seem to be any solution for adding/editing/deleting objects that are attached through a has_one.

Sorry I can't help, I'm looking into a way to do this.

thanks for help
i started using multiple upload field for this

For anyone still interested in implementing the ability to edit a `has_one` to another `DataObject` inline, they might find this particular extension helpful:
