I’m upgrading a site from SS2 to SS3 and there are a number of Images which are managed by ImageDOM which I am trying to move to Gridfield.

Usually I will have this:

class CustomImage extends DataObject {

   public static $has_one = array (
      'MyImage' => 'Image',
   );
	
   static $summary_fields = array(
      'Thumbnail' => 'Thumbnail'
   ); 

   public function getThumbnail() { 
      return $this->MyImage()->CMSThumbnail();
   }
}

Then if I create a gridfield Record Editor on a page this automatically gives me a thumbnail.


class Page extends SiteTree {

...

   public static $has_many = array(
      'CustomImages' => 'CustomImage',
   );

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

      $conf=GridFieldConfig_RecordEditor::create(10);
      $fields->addFieldToTab("Root.CustomImages", new GridField('CustomImages','', $this->CustomImages(), $conf));

      return $fields;
   }

...
}

Is it possible to adapt this to work on the basic Image class? So far I have tried this, wihch I feel may be close, but I can’t work out how to get it to work.


class Page extends SiteTree {

...

   $has_many = array(
      'MyImages' => 'Image'
   )

...

   public function getThumbnail() { 
      return $this->Image()->CMSThumbnail();
   }	

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

      $conf=GridFieldConfig_RecordEditor::create(10);
      $conf->getComponentByType('GridFieldDataColumns')
            ->setDisplayFields(array(
                  'Thumbnail' => 'Thumbnail'		
                  'Title' => 'Title'
               )) ;				
      $fields->addFieldToTab("Root.MyImages", new GridField('MyImages','', $this->MyImages(), $conf));
      return $fields;
}

Is it possible to display a thumbnail, or should I just re-organise the site structure?

After getting away from the screen for a few minutes and coming back I solved it almost straight away:


	public function getThumbnail() { 
	     return $Image()->CMSThumbnail();
	}	

...

	->setDisplayFields(array(
		'Image' => 'CMSThumbnail',			
		'Title' => 'Title'
	)) 		
	;
