I was wondering how to get the Filename of the attached file. My DataObject Video with $has_one = array('Attachment' => 'FLV').
On my ManyManyFileDataObjectManager I have
$filelist = array('Name' => 'Name')
but that doesn't work because Video doesn't have a Name Column in the database. I thought that putting a function on Video like this
function Name() {return $this->Attachment()->Name;} would do it but it doesn't
