Migrating from Has-many File Manager to DataObject Manager

Hi all,

I'm considering replacing the Has-many File Manager module on my site with the DataObject Manager. Has anyone else done this?

On [url=]my company site[/url] I am currently displaying images using this code:

<% if AttachedFiles(MyImages) %>
<div id="imgGallery">
<% control AttachedFiles(MyImages) %>
<% if First %><a href="$URL" title="$Title" rel="lightbox" class="storbild">$SetWidth(370)</a><% end_if %>
<a href="$URL" title="$Title" class="miniatyr">$SetWidth(80)</a>
<% end_control %>
<% end_if %>

This shows the first image attached to the page as a large preview, and the following images as miniatures beneath it.

How would one accomplish the same thing using the DataObject Manager?

DOM is not a frontend tool -- it's used in the backend to manage your data relationships, so the only difference is that you would have a more robust interface for uploading/managing your file objects in the CMS.

So the code can stay exactly the same? Excellent!

Is DOM fully compatible with SS 2.4.0? I thought I'd upgrade while I'm at it.

No, totally different code. The big difference between FileDOM and HasManyDOM, from a code standpoint, is that HasManyDOM requires you to decorate your File object for custom fields, while a FileDOM manages DataObjects that contain files, e.g.

MyUploadable extends DataObject
static $db = array (
'CustomField' => 'Text',
'AnotherCustomField' => 'Varchar'

static $has_one = array (
'File' = 'File'

public function getCMSFields() {
// etc..

Sorry for digging out an old thread. I stumbled across this and thought I might add a link to a solution on how to migrate Has-many File Manager to DOM:

Just in case anybody else finds this thread.
