EDIT: cleaned up the code for easier reading.

I'm trying to make a set of pages that contain multiple slideshows.

It's supposed to look basically like this...Images have a many to one relationship with a slideshow and a slideshow has a many to many relationship across several pages/types.

I've set up a templateless class to house my slideshows, but I'm missing how exactly to access these slideshows and display them on their related template. It would seem I have the relationships correct as I can create a slideshow in teh holder and from the pages that I want the slideshow to appear on, I can select that slideshow in the cms. See screenshots. I'm just not sure how to display them.

Thanks a ton, to anyone that can take a look at this!

Here is the code for the Images and Slideshow:

/mysite/code/SlideImage.php

class SlideImage extends DataObject {
	static $db = array(
		'Label' => 'Text',
		'SlideOrder' => 'Text'
	);
	static $has_one = array('Image' => 'Image');
	static $belongs_many_many = array('SlideshowBuckets' => 'SlideshowBucket');
	function getCMSFields_forPopup() {
		$fields = new FieldSet();
		$fields->push( new TextField('Label'));
		$fields->push( new TextField('SlideOrder'));
		$fields->push( new ImageField('Image'));
		return $fields;
	}
}

/mysite/code/SlideshowBucket.php

class SlideshowBucket extends Page {
	static $allowed_children = array();
	static $db = array(
		'Headline' => 'Text',
		'Copy' => 'Text',
		'Link' => 'Text'
	);
	static $many_many = array('SlideImages' => 'SlideImage');
	static $belongs_many_many = array(
		'WorkContentDetailPages' => 'WorkContentDetailPage',
		'WorkHomePages' => 'WorkHomePage'
	);
	function getCMSFields() {
		$fields = parent::getCMSFields();
		$fields->addFieldToTab('Root.Content.Main', new TextField('Headline'));
		$fields->addFieldToTab('Root.Content.Main', new TextareaField('Copy'));
		$fields->addFieldToTab('Root.Content.Main', new TextField('Link'));
		$fields->removeFieldFromTab('Root.Content.Main','Content');
		$modulesTablefield = new ManyManyComplexTableField(
			$this,
			'SlideImages',
			'SlideImage',
			array(
				'Label' => 'Image Label',
				'SlideOrder' => 'Image Order',
				'Image' => 'Image Preview'
			),
			'getCMSFields_forPopup'
		);
		$modulesTablefield->setAddTitle( 'An Image' );
		$fields->addFieldToTab('Root.Content.SlideImage',$modulesTablefield);
		return $fields;
	}
}

And finally, this is the pages that I want my slideshows to appear on:

/mysite/code/WorkContentDetailPage

class WorkContentDetailPage extends Page {
	static $allowed_children = array('SlideshowBucket');
	static $many_many = array('SlideshowBuckets' => 'SlideshowBucket');
	function getCMSFields() {
		$fields = parent::getCMSFields();
		$modulesTablefield = new ManyManyComplexTableField(
			$this,
			'SlideshowBuckets',
			'SlideshowBucket',
			array(
				'Title' => 'Title',
				'Headline' => 'Headline'
			),
			'getCMSFields_forPopup'
		);
		$modulesTablefield->setAddTitle( 'A Slideshow Module' );
		$fields->addFieldToTab('Root.Content.SlideshowBucket',$modulesTablefield);
		return $fields;
	}
}
class WorkContentDetailPage_Controller extends Page_Controller {}

So...

Adding a function to the page controller to actually call the dataobject was helpful:

	function workSlidesBucket() {
		return DataObject::get("SlideshowBucket", "xxxxx", "xxxxx");
	}

EDIT:
Additionally, I was using <% control children %> instead of using <% control SlideshowBuckets %> in my template file. Hope this helps someone.
