Ok.. So I built the pagetype ProjectHOlder who is supposed to have many projects and under the Project Page a lot of images( different for each project).
The problem is that when I go to the CMS it shows up the images from my slideshow on the homepage. I copied and pasted the code from my slideshow and renamed the classes to ProjectPage

<?php

// /mysite/code/GalleryPage.php

class ProjectPage extends Page

{

    static $has_many = array (

        'Images' => 'ImageResource'

    );

    public static $db = array(
	'YoutubeURL'=>'Text'

    );

    public static $has_one =  array('Before'=>'Image', 'Design'=>'Image');

 

    public function getCMSFields()

    {

        $f = parent::getCMSFields();


        $manager = new ImageDataObjectManager(

            $this, // Controller

            'Images', // Source name

            'ImageResource', // Source class

            'Attachment', // File name on DataObject

            array(

                'Caption' => 'Caption', 

                'Link' => 'Link'

            ), // Headings 

            'getCMSFields_forPopup' // Detail fields

            // Filter clause

            // Sort clause

            // Join clause

        );
	$f->addFieldToTab('Root.Content.Main', new TextField($name='YoutubeURL',$title="YouTube Video ID: /watch?v=XXXXX&"), 'Content');
  	$f->addFieldToTab("Root.Content.BeforeAndDesign", new ImageField('Before'));
	$f->addFieldToTab("Root.Content.BeforeAndDesign", new ImageField('Design'));


        $f->addFieldToTab("Root.Content.Gallery",$manager);
	

        return $f;

    }

}

 

class ProjectPage_Controller extends Page_Controller {

}

ProjectHolder.php

<?php
/**
 * Defines the ProjectHolder page type
 */
class ProjectHolder extends Page {
   static $db = array(
   );
   static $has_one = array(
   );
 
   static $allowed_children = array('ProjectPage');
}
 
class ProjectHolder_Controller extends Page_Controller {
 
}
 
?>

ImageResource.php
<?php 



class ImageResource extends DataObject

{

    static $db = array (

        

        'Caption' => 'Text',

		'Link' => 'Text'

    );

 

    static $has_one = array (

        'Attachment' => 'Image',

        'GalleryPage' => 'GalleryPage'
 /* This is where i think i should put something, gallerypage is my slideshow-- i need project page  */
    );

 

    public function getCMSFields_forPopup()

    {

        return new FieldSet(

            new TextField('Caption'),

            new TextField('Link'),

            new FileIFrameField('Attachment')

        );

    }

}

I am assuming it has something to do with the has one has many so it can link the attachments to just one gallery, I just don't know it.
Help Please :)

Shouldn't that be a $has_one ProjectPage? What is GalleryPage?

GalleryPage is the other gallery I have on my site. Its a slideshow manager.

class GalleryPage extends Page

{

    static $has_many = array (

        'Images' => 'ImageResource'

    );

    public static $db = array(

    );

    public static $has_one = array(

    );

 

    public function getCMSFields()

    {

        $f = parent::getCMSFields();

        $manager = new ImageDataObjectManager(

            $this, // Controller

            'Images', // Source name

            'ImageResource', // Source class

            'Attachment', // File name on DataObject

            array(

                'Caption' => 'Caption', 

                'Link' => 'Link'

            ), // Headings 

            'getCMSFields_forPopup' // Detail fields

            // Filter clause

            // Sort clause

            // Join clause

        );

        $f->addFieldToTab("Root.Content.Gallery",$manager);

        return $f;

    }

}

 

class GalleryPage_Controller extends Page_Controller {

}

Hi,

I once had the same problem and solved it with a custom filter and a new database-entry in the class that extends Dataobject, this would be ImageResource in your case.
I described the steps here: http://www.silverstripe.org/dataobjectmanager-module-forum/show/14434#post293616

I think in your case, you just have to use the filter on your ImageDataObjectManger and you should be fine, the additional steps with onAfterWrite() won't be required, I think...

Best regards,
