Event Calendar + File Download

Hi All,

I have the event calendar module installed, I like it very much and I would like to extend it a bit so that I can allow a file download associated with a calendar event (eg. Download a registration form). I have made the following changes and I need some help figuring out why they didn't work:


    static $has_many = array (
        'Resources' => 'Resource'

My resource class is exactly as found at (excepting I included different categories).
    public function getCMSFields()
        $f = parent::getCMSFields();
        $manager = new FileDataObjectManager(
                'Name' => 'Name', 
                'Description' => 'Description', 
                'Category' => 'Category'
        return $f;


When I log onto the CMS the extra 'Files' tab is there for a calendar event as expected, I can go about choosing a file to upload and in list or grid view I can see the file once it's uploaded. The problem I have is (and this might be related to why I cant get the file to show up on the website) when I click on the file a new popup-type window shows with the darkened background but it displays a Silverstripe error:

[User Error] Couldn't run query: SELECT "Resource"."ClassName", "Resource"."Created", "Resource"."LastEdited", "Resource"."Name", "Resource"."Description", "Resource"."Category", "Resource"."AttachmentID", "Resource"."ResourcePageID", "Resource"."ID", CASE WHEN "Resource"."ClassName" IS NOT NULL THEN "Resource"."ClassName" ELSE 'Resource' END AS "RecordClassName" FROM "Resource" WHERE ("ParentID" = '97') Unknown column 'ParentID' in 'where clause'

It's got me buggered.
I'm hoping I can display the file download on the website by modifying with:

    <% if Resources %>
        <% control Resources %>
            <li>$Name</li>  // Need to know how to hyperlink here.  $Attachment.URL ??
        <% end_control %>
    <% else %>
        <p>This calendar event has no attachments.</p>
    <% end_if %>

I'm new at php and not entirely sure if that's the correct usage of a control block. I'm wondering,
<% control Resources %>
should fetch me an array of Resource objects? How can I find out what member attributes of Resource I can access?

That's a rather long-winded description of the problem, I hope it's clear. Help at this stage would be much appreciated.
