Hi,

I've created a DataObject called ClinicalCenter, then created a ModelAdmin for it, added couple of Clinical Centers, and everything seams to work perfectly. Then created a PageHolder called ClinicalCentersPage to fetch and list all these centers, but nothing appears on the front end.

Appreciate your help guys.

Here is my codes

ClinicalCenter.php

class ClinicalCenter extends DataObject {

	private static $db = array(
		'Title' => 'Varchar',
		'Description' => 'HTMLText',
		'Active' => 'Boolean'
	);


	private static $has_one = array(
		'FeaturedImage' => 'Image',
		'ClinicalCentersPage' => 'ClinicalCentersPage'
	);

	
	private static $summary_fields = array(
		// summary fields goes here ...
	);



	public function getCMSFields() {
		
		$fields = FieldList::create(TabSet::create('Root'));
		
		$fields->addFieldsToTab('Root.Main', array(
			
			TextField::create('Title', 'Clinical Center Name'),
			HtmlEditorField::create('Description', 'Describe this Clinical Center'),
			CheckboxField::create('Active', 'Is the Center Active?'),
			$upload = UploadField::create('FeaturedImage', 'Featured Image')
		
		));
		
		$upload->getValidator()->setAllowedExtensions(array(
			'png', 'jpg', 'jpeg', 'gif'
		));
		
		$upload->setFolderName('clinical-images');

		return $fields;
	}
}

ClinicalCentersAdmin.php

class ClinicalCentersAdmin extends ModelAdmin {
	
	private static $menu_title = 'Clinical Centers';
	
	private static $url_segment = 'clinical-centers';
	
	private static $managed_models = array(
		'ClinicalCenter'
	);

	private static $menu_icon = 'mysite/icons/medical-icon.png';
}

ClinicalCentersPage.php

class ClinicalCentersPage extends Page {

    private static $has_many = array(
        'ClinicalCenters' => 'ClinicalCenter'
    );

}

class ClinicalCentersPage_Controller extends Page_Controller {
}

ClinicalCentersPage.ss

<div class="row">

<% loop $ClinicalCenters %>

	<div class="col-lg-3">
		<div class="box">
			<div class="box-gray aligncenter">
				<h4>$Title</h4>
				<div class="icon">
					$FeaturedImage.CroppedImage(242,156)
				</div>
				<p>
				 $Description.FirstSentence
				</p>
			</div>
			<div class="box-bottom">
				<a href="$Link">View</a>
			</div>
		</div>
	</div>

<% end_loop %>

</div>

Please help guys, where I'm going wrong?

Though you created the data-relation on ClinicalCenter with ClinicalCentersPage, they are not shown in cms section via getCMSFields, so i would recommend you add the below mentioned code to link the ClinicalCenter with ClinicalCentersPage,

$page = DropdownField::create('ClinicalCentersPageID', 'ClinicalCentersPage', ClinicalCentersPage::get()->map('ID', 'Title'))

class ClinicalCenter extends DataObject {

	private static $db = array(
		'Title' => 'Varchar',
		'Description' => 'HTMLText',
		'Active' => 'Boolean'
	);


	private static $has_one = array(
		'FeaturedImage' => 'Image',
		'ClinicalCentersPage' => 'ClinicalCentersPage'
	);

	
	private static $summary_fields = array(
		// summary fields goes here ...
	);



	public function getCMSFields() {
		
		$fields = FieldList::create(TabSet::create('Root'));
		
		$fields->addFieldsToTab('Root.Main', array(
			
			TextField::create('Title', 'Clinical Center Name'),
			HtmlEditorField::create('Description', 'Describe this Clinical Center'),
			CheckboxField::create('Active', 'Is the Center Active?'),
			$upload = UploadField::create('FeaturedImage', 'Featured Image'),
		        $page = DropdownField::create('ClinicalCentersPageID', 'ClinicalCentersPage', ClinicalCentersPage::get()->map('ID', 'Title'))              
		));
		
		$upload->getValidator()->setAllowedExtensions(array(
			'png', 'jpg', 'jpeg', 'gif'
		));
		
		$upload->setFolderName('clinical-images');

		return $fields;
	}
}
