I have similar issue.

I have News Holder and News Post. But I Have extended Blog Holder and Blog Entry respectively.
Can I change this to DataObject while inheriting from Blog Entry?

I am a designer who can manage to code with little help :)

Current Code for NewsPost is

class NewsPost extends BlogEntry {
   static $db = array (
'GalleryImageWidth' => 'Int',
'Featured' => 'Boolean',
'UserPost' => 'Boolean',
   static $default_parent = 'NewsHolder';
   static $can_be_root = false;
   static $has_one = array(
      'Photo' => 'Image'

      //'Gallery' => 'ImageGalleryPage'
      //'GalleryImages' => 'GalleryImage'
   static $has_many = array (
'GalleryImages' => 'GalleryImage'

public function init() {

// Note: you should use SS template require tags inside your templates
// instead of putting Requirements calls here. However these are
// included so that our older themes still work


   function getCMSFields() {
   $fields = parent::getCMSFields();
$fields->addFieldsToTab("Root.Content.Main", new CheckboxField('UserPost', "Post by a Member"));
   $fields->addFieldToTab("Root.Content.Main", new CheckboxField('Featured', "Featured Post"));
   $fields->addFieldToTab("Root.Content.Images", $leadImage= new ImageField('Photo', "Upload your lead image here"));
      $leadImage->setFolderName('Uploads/' .date("Y").'/' .date("m"));
   $fields->addFieldToTab("Root.Content.Configuration", $myField= new NumericField('GalleryImageWidth', 'Image Width'));
      /*$fields-> addFieldToTab ("Root.Content.Gallery", new DropdownField("GalleryID", "Gallery",
         DataObject::get("ImageGalleryPage")->toDropdownMap(), 'Content'));*/
      $manager = new ImageDataObjectManager(
$this, // Controller
'GalleryImages', // Source name
'GalleryImage', // Source class
'MyGalleryImage', // File name on DataObject
'GalleryImageTitle' => 'GalleryImageTitle'
), // Headings
'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
// Filter clause
// Sort clause
// Join clause
$fields->addFieldToTab('Root.Content.GalleryImage', $manager);
return $fields;

// Function for SideBar
function GetSidebarContent($num=3) {

//$randomNumber =
$sidebarContent = DataObject::get_one("SidebarContent");

return false;

$contents = array();

$contents[] = DBField::create('Varchar', $sidebarContent->Content1);
$contents[] = DBField::create('Varchar', $sidebarContent->Content2);
$contents[] = DBField::create('Varchar', $sidebarContent->Content3);
$contents[] = DBField::create('Varchar', $sidebarContent->Content4);
$contents[] = DBField::create('Varchar', $sidebarContent->Content5);


//return new DataObjectSet(array_rand($contents, $num));
return new DataObjectSet(array_slice($contents, 0, $num));
//return new DataObjectSet($contents);


class NewsPost_Controller extends BlogEntry_Controller{


* Replaces Images to a predefined max width and adds a nyroModal class to the image
* In template use : $Content.Parse(ArticleImageParser)

class ArticleImageParser extends TextParser{
   public function parse() {
      // match image src
      $pattern = '/<img[^>]+src[\\s=\'"]';
      $pattern .= '+([^"\'>\\s]+)/is';
         $i = 0;
         foreach ($match[0] as $m){   
            //var_dump($m); //"<img class="right" src="assets/Articles/installingsilverstripe/wampserver.jpg"
            // get original image url
            $href = preg_replace('/_resampled\/resizedimage[0-9]*-/', '', $match[1][$i]);
            // add a tag with original image url
            $this->content   = str_replace ($m,'<a class="popImage" rel="grp-all" href="'.$href.'">'.$match[0][$i],$this->content);
         // add missing </a> tag after each image
         $this->content = preg_replace('/<img[^>]+>/', '${0}</a>', $this->content);
      return $this->content;
