I am having an issue that despite having all the files showing up with in the back end, I can't get them to render on the front end...

This is my code

class Download extends DataObject {
static $db = array(
'date' => 'Text',
'description' => 'Text'
static $has_one = array(
'TheDownload' => 'File'

static $belongs_many_many = array (
'Download' => 'Downloads'

function getCMSFields_forPopup() {
$fields = new FieldSet();
$fields->push(new TextField('date','Date Created'));
$fields->push(new TextField('description','Description of file'));
$fields->push(new FileIFrameField('TheDownload'));
return $fields;

class Downloads extends Page {
static $db = array(

static $has_one = array(


static $many_many = array(
'TheDownloads' => 'Download'


function getCMSFields() {

$fields = parent::getCMSFields();

$manager = new FileDataObjectManager(
$this, // Controller
'TheDownloads', // Source name
'Download', // Source class
'TheDownload', // File name on DataObject
'Date' => 'Date',
'Description' => 'Description',
), // Headings
'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
// Filter clause
// Sort clause
// Join clause
return $fields;


<table class="downloads">
<% control TheDownloads %>
<td><a href="$TheDownload.URL" target="_new"><img src="/themes/howell/images/icons/page_white_acrobat.png" alt="Download "/></a></td>
<% end_control %>

Any ideas as to what I am doing? It just outputs the table headers and nothing else ->

The biggest issue you have is that you're using a FileDOM to manage a many_many relationship, when you should be using a MMFileDOM.

The other thing is that your naming conventions are extremely confusing and redundant. I wouldn't be surprised if that's tripping up the ORM. You have two fields named "TheDownload".. "Download" is a belongs_many_many field and it's also a class. I don't know how you keep track of all that!
